Coupled with its existing GaN manufacturing in Dallas, Texas, TI will now internally manufacture four times more GaN-based power semiconductors, as Aizu ramps to production.
“Building on more than a decade of expertise in GaN chip design and manufacturing, we have successfully qualified our 200mm GaN technology – the most scalable and cost-competitive way to manufacture GaN today – to start mass production in Aizu,” said Mohammad Yunus, TI’s senior vice president of Technology and Manufacturing. “This milestone enables us to manufacture more of our GaN chips internally as we grow our internal manufacturing to more than 95% by 2030, while also sourcing from multiple TI locations, ensuring a reliable supply of our entire GaN portfolio of high-power, energy-efficient semiconductors.”
An alternative to silicon, GaN is a semiconductor material that offers benefits in energy-efficiency, switching speed, power solution size and weight, overall system cost, and performance under high temperatures and high-voltage conditions. GaN chips provide more power density, or power in smaller spaces, enabling applications such as power adapters for laptops and mobile phones, or smaller, more energy-efficient motors for heating and air conditioning systems and home appliances.
Today, TI offers the widest portfolio of integrated GaN-based power semiconductors, ranging from low- to high-voltage, to enable the most energy-efficient, reliable and power-dense electronics.
“With GaN, TI can deliver more power, more efficiently in a compact space, which is the primary market need driving innovation for many of our customers,” said Kannan Soundarapandian, vice president of High-Voltage Power at TI. “As designers of systems such as server power, solar energy generation and AC/DC adapters face challenges to reduce power consumption and enhance energy efficiency, they are increasingly demanding a reliable supply of TI’s high-performance GaN-based chips. TI’s product portfolio of integrated GaN power stages enables customers to achieve higher power density, improved ease of use and lower system cost.”
Further, with the company’s proprietary GaN-on-silicon process, more than 80 million hours of reliability testing, and integrated protection features, TI GaN chips are designed to keep high-voltage systems safe.
Using the most advanced equipment available for GaN chip manufacturing today, TI’s new capacity enables increased product performance and manufacturing process efficiency, as well as a cost advantage. Also, the more advanced, efficient tools used in TI’s expanded GaN manufacturing can produce smaller chips, packing even more power. This design innovation can be manufactured using less water, energy and raw materials, and end products that use GaN chips enjoy these same environmental benefits.
The performance benefits of TI’s added GaN manufacturing also enable the company to scale its GaN chips to higher voltages, starting with 900V and increasing to higher voltages over time, furthering power-efficiency and size innovations for applications like robotics, renewable energy and server power supplies.
In addition, TI’s expanded investment includes a successful pilot earlier this year for development of GaN manufacturing processes on 300mm wafers. Further, TI’s expanded GaN manufacturing processes are fully transferable to 300mm technology, positioning the company to readily scale to customer needs and move to 300mm in the future.
Expanding supply and innovation in GaN technology is the latest example of TI’s commitment to responsible, sustainable manufacturing. TI has committed to use 100% renewable electricity in its U.S. operations by 2027, and worldwide by 2030.

The product family is suitable for applications with DC link voltages up to 1500 VDC and offers current ratings from 10 to 80 A. This makes it ideal for higher DC link voltage applications such as in solar and EV charging applications.
The product family comes in a TO-247PLUS-4-HCC package, with 14 mm creepage and 5.4 mm clearance distance. This, together with a current rating of up to 80 A, enables a significantly higher power density. It allows developers to achieve higher power levels in their applications with only half the component count of 1200 V solutions. This simplifies the overall design and enables a smooth transition from multi-level topologies to 2-level topologies.
In addition, the CoolSiC Schottky diode 2000V G5 utilizes the .XT interconnection technology that leads to significantly lower thermal resistance and impedance, enabling better heat management. Furthermore, the robustness against humidity has been demonstrated in HV-H3TRB reliability tests.

Affordability combined with high performance and efficiency is the key to making electric mobility accessible to a broader market. That’s why Infineon Technologies AG is introducing the HybridPACK™ Drive G2 Fusion, establishing a new power module standard for traction inverters in the e-mobility sector.
The HybridPACK Drive G2 Fusion is the first plug’n’play power module that implements a combination of Infineon’s silicon and silicon carbide (SiC) technologies. This cutting-edge solution provides an ideal balance between performance and cost efficiency, giving more choice in the optimization of inverters.
One of the main differences between silicon and SiC in power modules is that SiC has a higher thermal conductivity, breakdown voltage and switching speed, making it more efficient, but also more expensive than silicon-based power modules. With the new module, the SiC content per vehicle can be reduced, while maintaining vehicle performance and efficiency at a lower system cost. For example, system suppliers can realize nearly the system efficiency of a full SiC solution with only 30 percent SiC and 70 percent silicon area.
“Our new HybridPACK Drive G2 Fusion module underlines Infineon’s innovation leadership in the automotive semiconductor industry,” said Negar Soufi-Amlashi, Senior Vice President & General Manager High Voltage at Infineon’s Automotive division. “Addressing the demand for greater e-mobility range, this technological breakthrough smartly combines silicon carbide and silicon. Integrated in a well-introduced module package footprint it offers compelling cost-performance ratio over pure silicon carbide modules without adding system complexity for automotive system suppliers and vehicle manufacturers.”
HybridPACK Drive G2 Fusion expands Infineon’s HybridPACK Drive power module portfolio and can be quickly and easily integrated in vehicle components or modules without requiring complex adjustments or configurations. The HybridPACK Drive G2 Fusion module features up to 220 kW in the 750 V class. It ensures high reliability over the entire temperature range from -40 °C to +175 °C and improved thermal conductivity.
The unique properties of Infineon’s CoolSiC™ technology and its silicon IGBT EDT3 technology with very fast turn-on enable the use of a single gate driver or dual gate drivers. This allows easy re-design from full silicon or full SiC based inverters to a fusion inverter. Generally, Infineon’s holistic expertise in SiC MOSFET and silicon IGBT technology, power module packaging, gate drivers as well as sensors enables premium products with cost savings at system level. One example is the integration of Swoboda or XENSIV™ Hall sensors in the HybridPACK Drive package for more precise and efficient motor control.
Infineon will showcase the new HybridPACK Drive G2 Fusion at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).
