Toshiba Electronic Devices & Storage Corporation and Toshiba Corporation (Toshiba Group) have developed technology that mitigates the parasitic oscillation that occurs during switching operations by power modules with silicon carbide (SiC) MOSFETs connected in parallel, even with a 60% smaller gate resistance than is typical. The technology reduces power loss in power modules, mitigates oscillation, and realizes highly reliable switching operations.
The drive for carbon neutrality is stimulating demand for technologies that improve energy efficiency in many areas, including renewables, railways, and industrial equipment. In these sectors, the application of power modules built around SiC MOSFETs is seen as a solution that supports high-speed switching at high voltages and large currents—which is particularly important for the miniaturization of power converters, where higher switching frequencies result in higher rates of switching losses against power consumption.
Connecting multiple chips in parallel in power modules can form oscillation circuits, the result of wiring inductance between the chips and their parasitic capacitance. It can reduce module reliability if not countered, which is usually done by increasing gate resistance. However, this approach slows switching speed, resulting in a trade-off with switching losses. For power modules with SiC MOSFETs to perform high-speed switching, another approach is needed.
Toshiba Group used an equivalent circuit model of the power module (Figure 1) to determine the theoretical condition that triggers parasitic oscillation, and developed a wiring layout less likely to cause it. This was done by analyzing simulations of parasitic oscillation occurs when Lg/Ls, the ratio of gate-to-gate inductance Lg and source-to-source inductance Ls of parallel chips, is below a certain value (Figure 2). As increasing Lg/Ls is an effective means of mitigating parasitic oscillation, Toshiba Group fabricated prototype modules with different Lg/Ls and measured switching. This confirmed that increasing Lg/Ls mitigated oscillation, even with a 60% smaller gate resistance than that required by the alternative approach of increasing gate resistance (Figure 3).
Applying this approach to oscillation mitigation in power modules now under development has realized a power module less likely to cause parasitic oscillation, even with minimal gate resistance, that achieves low power loss with mitigated oscillation, and delivers highly reliable switching operation. Toshiba Group will continue to make refine the modules toward an early product launch.
Toshiba Group presented the details of this technology on June 6 at the 36th International Symposium on Power Semiconductor Devices and ICs (ISPSD) 2024, an international power semiconductor conference held in Bremen, Germany from June 2 to 6.

Navitas Semiconductor released its 4.5 kW AI data center power supply reference design, with optimized GaNSafe™ and Gen-3 ‘Fast’ (G3F) SiC power components. The optimized design enables the world’s highest power density with 137 W/in3 and over 97% efficiency.
Next-generation AI GPUs like NVIDIA’s Blackwell B100 and B200 each demand over 1 kW of power for high-power computation, 3x higher than traditional CPUs. These new demands are driving power-per-rack specifications from 30-40 kW up to 100 kW.
Navitas announced its AI Power Roadmap in March 2024, showcasing next-generation data center power solutions for the growing demand in AI and high-performance computing (HPC) systems. The first design was a GaNFast-based 3.2 kW AC-DC converter in the Common Redundant Power Supply (CRPS) form factor, as defined by the hyperscale Open Compute Project. The 3.2 kW CRPS185 (for 185 mm length) enabled a 40% size reduction vs. the equivalent legacy silicon approach and easily exceeded the ‘Titanium Plus’ efficiency benchmark, critical for data center operating models and a requirement for European data center regulations.
Now, the latest 4.5 kW CRPS185 design demonstrates how new GaNSafe™ power ICs and GeneSiC Gen-3 ‘Fast’ (G3F) MOSFETs enables the world’s highest power density and efficiency solution. At the heart of the design is an interleaved CCM totem-pole PFC using SiC with full-bridge LLC topology with GaN, where the fundamental strengths of each semiconductor technology are exploited for the highest frequency, coolest operation, optimized reliability and robustness, and highest power density and efficiency. The 650 V G3F SiC MOSFETs feature ‘trench-assisted planar’ technology which delivers world-leading performance over temperature for the highest system efficiency and reliability in real-world applications.
For the LLC stage, 650 V GaNSafe power ICs are ideal and unique in the industry with integrated power, protection, control, and drive in an easy-to-use, robust, thermally-adept TOLL power package. Additionally, GaNSafe power ICs offer extremely low switching losses, with a transient-voltage capability up to 800 V, and other high-speed advantages such as low gate charge (Qg), output capacitance (COSS), and no reverse-recovery loss (Qrr). High-speed switching reduces the size, weight, and cost of passive components in a power supply, such as transformers, capacitors, and EMI filters. As power density increases, next-gen GaN and SiC enable sustainability benefits, specifically CO2 reductions due to system efficiency increases and ‘dematerialization’.
The 3.2 kW and 4.5 kW platforms have already generated significant market interest with over 30 data center customer projects in development expected to drive millions in GaN and SiC revenue, ramping from 2024 into 2025.
Navitas’ AI data center power supply reference designs dramatically accelerate customer developments, minimize time-to-market, and set new industry benchmarks in energy efficiency, power density and system cost, enabled by GaNFast power ICs and GeneSiC MOSFETs. These system platforms include complete design collateral with fully tested hardware, embedded software, schematics, bills-of-material, layout, simulation, and hardware test results.
“AI is dramatically accelerating power requirements of data centers, processors and anywhere AI is going in the decades to come creating a significant challenge for our industry. Our system design center has stepped up to this challenge delivering a 3x increase in power in less than 18 months”, said Gene Sheridan, CEO of Navitas Semiconductor. “Our latest GaNFast technology, combined with our G3F SiC technology are delivering the highest power density and efficiency the world has ever seen…the perfect solution for the Blackwell AI processors and beyond.”

“The future of electrification is dependent on advanced power semiconductors. Today’s infrastructure cannot keep up with the world’s demands for more intelligence and electrified mobility without significant innovations in power. This is critical to the ability to achieve global electrification and stop climate change,” said Simon Keeton, group president, Power Solutions Group, onsemi. “We are setting the pace for innovation, with plans to significantly increase power density in our silicon carbide technology roadmap through 2030 to be able to meet the growing demands for energy and enable the global transition to electrification.”
The EliteSiC M3e MOSFETs will play a fundamental role in enabling the performance and reliability of next-generation electrical systems at lower cost per kW, thus influencing the adoption and effectiveness of electrification initiatives. With the ability to operate at higher switching frequencies and voltages while minimizing power conversion losses, this platform is essential for a wide range of automotive and industrial applications such as electric vehicle powertrains, DC fast chargers, solar inverters and energy storage solutions.
Additionally, the EliteSiC M3e MOSFETs will enable the transition to more efficient, higher-power data centers to meet the exponentially increasing energy demands that power a sustainable artificial intelligence engine.
Through onsemi’s unique design engineering and manufacturing capabilities, the EliteSiC M3e MOSFETs achieve a significant reduction in both conduction and switching losses on the trusted and field-proven planar architecture. Compared to previous generations, the platform can reduce conduction losses by 30% and turn-off losses by up to 50%.
By extending the life of SiC planar MOSFETs and delivering industry-leading performance with EliteSiC M3e technology, onsemi can ensure the robustness and stability of the platform, making it a preferred choice for critical electrification applications
The EliteSiC M3e MOSFETs also offer the industry’s lowest specific on-resistance (RSP) with short circuit capability which is critical for the traction inverter market that dominates SiC volume. Packaged in onsemi’s state-of-the-art discrete and power modules, the 1200V M3e die delivers substantially more phase current than previous EliteSiC technology, resulting in approximately 20% more output power in the same traction inverter housing. Conversely, a fixed power level can now be designed with 20% less SiC content, saving costs while enabling the design of smaller, lighter and more reliable systems.
Additionally, onsemi provides a broader portfolio of intelligent power technologies including gate drivers, DC-DC converters, e-Fuses and more to pair with the EliteSiC M3e platform. The end-end onsemi combination of optimized, co-engineered power switches, drivers and controllers enable advanced features via integration, lowering overall system cost.
Global energy demands are projected to soar over the next decade, making the need for increased power density in semiconductors paramount. onsemi is leading innovation across its silicon carbide roadmap – from die architectures to novel packaging techniques – that will continue to address the general industry demand for increased power density.
With each new generation of silicon carbide, cell structures will be optimized to efficiently push more current through a smaller area, increasing power density. When coupled with the company’s advanced packaging techniques, onsemi will be able to maximize performance and reduce package size.
By applying the concepts of Moore’s Law to the development of silicon carbide, onsemi can develop multiple generations in parallel and accelerate its roadmap to bring several new EliteSiC products to market at an accelerated pace through 2030.
“We are applying our decades of experience in power semiconductors to push the boundaries of speed and innovation in our engineering and manufacturing capabilities to meet the rising global energy demands,” said Dr. Mrinal Das, senior director of technical marketing, Power Solutions Group, onsemi. “There is a huge technical interdependency between the materials, device and package in silicon carbide. Having full ownership over these key aspects allows us to have control over the design and manufacturing process and bring new generations to market much faster.”

SMC Diode Solutions, an American-led semiconductor design and manufacturing company, celebrated the opening of its second power discrete fab in Nanjing, China. The new facility realized volume production only 21 months after groundbreaking in September of 2022, and will begin shipments to customers in Q4 2024 for high power and high voltage rectifiers and MOSFET 6-inch and 8-inch wafers.
This new fab marks a milestone in SMC’s growth as they further invest in the China market and the growing renewable energy sector. The new 300,000 square foot facility is set to produce 1.2 million silicon wafers and 60,000 silicon carbide wafers per year, increasing SMC’s total production by over four times. SMC’s current fab in Lukou, Nanjing currently produces 300,000 silicon wafers per year. The $3 billion RMB investment in the new fab will allow SMC to handle the end-to-end production of silicon carbide products for the first time and has created three hundred new jobs.
“As the world moves towards using more and more renewable energy, we are thrilled to now be able to participate in the sector and be part of the solution to increase green energy usage and protect our Earth. We are very excited to have our new fab up and running and we look forward to servicing our customers’ needs better with the increased capacity.” – Dr. Yunji Corcoran, SMC chairwoman and chief executive officer.
As Nanjing is also home to SMC’s current fab, the city was an advantageous choice for the new fab location. With their experienced management team, starting up the new fab was a seamless process, allowing production to begin not long after breaking ground. The city is also home to abundant resources and engineering talent, making it an ideal place for SMC to grow and expand.
Power Semiconductors Weekly team had pleasure to interview Dr. Yunji Corcoran on this occasion:
- The company history dates back to 1997. Can you tell us about some of the major milestones and your semiconductor journey so far?
Certainly. In the early stages of our company, from 1997 until about 2014, we focused on the US and South Korean markets. We were growing steadily, but remained focused on the quality of our products. From 2014 to 2019, we began to focus on active growth, but I consider this more of a preparation stage for our company’s expansion. We investigated ways to create better products and put more of our R&D efforts into new silicon and Silicon Carbide (SiC) products. We also began strengthening our salesforce globally. From 2019 on, we started shipping our new products, both silicon and SiC. Now, we have reached our most significant milestone to date: opening our second fab and quadrupling our production capabilities. We are beginning a new phase that will focus on growing our presence in the power semiconductor market.
- Today we see many semiconductor companies investing a lot of energy into the automotive, renewables, and AI applications. With a wide product line and a new wafer fab to support further expansion, what are your major areas of interest and how do you see them evolve in the coming years?
Automotive, renewables, and AI are extremely relevant markets for both our company and the overall semiconductor industry right now. AI requires a lot of power supply, so we plan to grow our power supply products in that area alongside our existing customers. Automotive and renewables are newer segments for us and the semiconductor market, but ones with incredibly high demand right now. The market is growing rapidly, so we are growing with aims to successfully compete in those areas as well.
Our plan is to focus on our growth within the power supply market and naturally expand into the sustainable energy market. As the world continues to prioritize clean energy, the demand for EV and renewable energy products will also grow. Since SiC products in particular meet the specific power needs of those applications, a rise in the use of SiC products seems likely. I suspect the semiconductor industry will play a crucial role in providing more clean energy globally, which we are excited to be a part of.
- With the new fab you plan to address both silicon and silicon carbide markets? What is your view on the growing demand for SiC and how SMC Diode Solutions plan to correspond to it?
Yes, our new fab will produce both silicon and SiC products. Our current fab produces approximately 300,000 silicon wafers per year, but our new fab has the capability to produce a total of 1,260,000 wafers per year – 1,200,000 silicon and 60,000 SiC. We are very much focused on our silicon power products and view our SiC line as a natural extension of that.
The growing demand for SiC products makes perfect sense. SiC is a material with remarkable properties. It is considered a “wide bandgap” material, which means that it requires more energy to excite electrons from the valence band to the conduction band compared to standard silicon semiconductors. As a result, it offers superior performance characteristics including higher reverse voltage capabilities and greater stability at high temperatures.
Overall, SiC-based products offer improved efficiency and reliability compared to traditional silicon counterparts. For a lot of newer applications, particularly in the sustainable energy sector, these capabilities have become more and more necessary. We see our new fab opening as a natural response to this demand, ande are increasing our capabilities to grow alongside the market.
- Today you have four major locations in China, South Korea, Germany and the USA. Do you plan to expand your network further?
Yes, definitely. We consider SMC to be a global company, and have a range of operations throughout the world, including our headquarters in China and other offices in the US, Germany, South Korea, the UK, and India. As we grow and gain customers throughout the world, we will continue to establish more locations, whether they are R&D, manufacturing, packaging, or sales offices.
- Speaking of the network and future growth opportunities. Both of your fabs are located in Nanjing. With many companies in the US already taking advantage of the CHIPS and Science Act, do SMC Diode Solutions have any considerations to join the rest and use this chance to strengthen the US presence?
It is exciting that governments are recognizing the importance of semiconductors through initiatives like the CHIPS and Science Act, and I think this will really bolster the industry as a whole. Right now, we’re focused on our manufacturing efforts in Asia, but are open to the possibility as we continue to grow.
- With the rise of the Chinese semiconductor industry and a very competitive landscape, how do you position your company and differentiate from the growing number of new entrants?
The key thing is our products. Our products stand out for their high quality and outstanding performance. Our team’s commitment to customer service really sets us apart as well.
Our company also approaches the semiconductor market from a unique perspective. As a business with global locations and leadership, we deeply understand the needs of the international market. We prioritize high quality standards that the international market demands while benefiting from relatively low overall production costs, creating an ideal product for our customers.
- We see many companies in China, Europe, the US, shifting to the vertical structure and full integration of all processes – from growing the semiconductor boules to the packaging of the final product. What are your thoughts on such an approach and do you see it applicable for your company in the future as well?
I’ve also noticed this trend in the industry. While I can see the benefits of this approach for some, I would not anticipate applying it within SMC. I believe in focusing our efforts on what we’re able to do best. We have specialized in design and manufacturing for over 25 years and plan to continue that.
We do have an existing silicon module line, so we are considering expanding into SiC modules in the future. However, for our company we believe it’s best to stay focused on the functions we currently have and prioritize delivering the highest quality product.
- And lastly, after the announcement of a new fab opening, many of your partners would be willing to engage in discussions to find out more. What trade shows or conferences in the second half of 2024 can they meet the company at?
We would love to engage in those discussions as well. You can find us with our own booth at Electronica 2024 this September in Munich, Germany and the Anaheim Electronics & Manufacturing Show (AEMS 2024) in Anaheim, California this October. We will also be attending ISCRM 2024 in Raleigh, North Carolina this fall.
More often than not, you will find someone from our company at any major semiconductor event. Feel free to contact us at sales@smc-diodes.com for any questions or check our website updates to see where you can find us next.
