    Infineon Technologies Unveils 650V CoolGaN™ Bidirectional Switch, Enabling Compact, Efficient Power Conversion for EVs, AI Data Centers, and Energy Systems

    3 Min Read

    Infineon Technologies AG has introduced the CoolGaN™ bidirectional switch (BDS) 650 V G5, a gallium nitride (GaN) switch capable of actively blocking voltage and current in both directions. Featuring a common-drain design and a double-gate structure, it leverages Infineon’s robust gate injection transistor (GIT) technology to deliver a monolithic bidirectional switch, enabled by Infineon’s CoolGaN technology. The device serves as a highly efficient replacement for traditional back-to-back configurations commonly used in converters.

    The bidirectional CoolGaN switch offers several key advantages for power conversion systems. By integrating two switches in a single device, it simplifies the design of cycloconverter topologies, enabling single-stage power conversion, eliminating the need for multiple conversion stages. This leads to improved efficiency, increased reliability, and a more compact design. BDS-based microinverters also benefit from higher power density and reduced component count, which simplifies manufacturing and reduces costs. Additionally, the device supports advanced grid functions such as reactive power compensation and bidirectional operation.

    As a result, this solution holds significant potential across a wide range of applications, including:

    Microinverters: The CoolGaN bidirectional switch enables simpler and more efficient microinverter designs, reducing both size and cost. This makes microinverters more attractive for residential and commercial solar installations.

    Energy Storage Systems (ESS): In ESS applications such as battery chargers and dischargers, the switch allows for more efficient and reliable energy storage and release.

    Electric Vehicle (EV) Charging: In EV charging systems, the BDS switch supports faster, more efficient charging while also enabling vehicle-to-grid (V2G) functionality, where energy stored in the vehicle battery can be fed back into the grid.

    Motor control: The CoolGaN BDS is ideal for use in Current Source Inverters (CSI) for industrial motor drives. Compared to traditional Voltage Source Inverters (VSI), CSIs offer benefits such as:

    • Producing a sinusoidal output voltage, which supports longer cable runs, reduced losses, and improved fault tolerance.
    • Replacing the DC-link capacitor with an inductor, improving high-temperature performance and short-circuit protection.
    • Higher efficiency at partial loads, lower EMI, inherent buck-boost capability for voltage variation, and scalability for parallel operation.

    These features make CSIs a more robust and efficient alternative for industrial motor applications.

    AI data centers: In AI server power supplies, bidirectional switches like CoolGaN support higher switching frequencies and power density in architectures such as Vienna rectifiers and H4 PFCs. A single CoolGaN BDS can replace two conventional switches, reducing component count, cost, size, and overall power losses.

    The CoolGaN bidirectional switch (BDS) 650 V G5 is available for ordering now as well as samples of the 110 mΩ product. More information is available here.

    Navitas Semiconductor Launches Industry-First ‘AEC-Plus’ Qualified SiC MOSFETs with HV-T2PaK Package for High-Reliability Automotive and Industrial Power Systems

    3 Min Read

    Navitas Semiconductor introduced a new level of reliability to meet the system lifetime requirements of the most demanding automotive and industrial applications. Navitas’ latest generation of 650 V and 1200 V ‘trench-assisted planar’ SiC MOSFETs combined with an optimized, HV-T2PaK top-side cooled package, delivers the industry’s highest creepage of 6.45 mm to meet IEC-compliance for applications up to 1200V.

    Navitas’ HV-T2PaK SiC MOSFETs significantly increase system-level power density and efficiency while improving thermal management and simplifying board-level design and manufacturability. Target applications include EV on-board chargers (OBC) & DC-DC converters, data-center power supplies, residential solar inverters & energy storage systems (ESS), EV DC fast chargers, and HVAC motor drives.

    AEC-Q101 is an automotive industry standard developed by the Automotive Electronics Council (AEC) to establish common part-qualification and quality-system standards. Navitas has created an industry-first benchmark, ‘AEC-Plus’*, indicating parts qualified above and beyond the existing AEC-Q101 and JEDEC product qualification standards. This new benchmark showcases Navitas’ deep understanding of system-level lifetime requirements and a strong commitment to enabling rigorously designed and validated products for demanding mission profiles in automotive and industrial applications.

    The ‘AEC-Plus’ qualification standards extend further into rigorous multi-lot testing and qualification. Key additions to the existing AEC-Q101 requirements include:

    • Dynamic reverse bias (D-HTRB) & dynamic gate switching (D-HTGB) to represent stringent application mission profiles
    • Over 2x longer power & temperature cycling
    • Over 3x longer duration for static high-temperature, high-voltage tests (e.g. HTRB, HTGB).
    • 200°C TJMAX qualification for overload operation capability

    Navitas’ HV-T2PaK top-side cooled package, in an industry-standard compact form factor (14 mm x 18.5 mm), is optimized with an innovative groove design in the package mold compound that extends the creepage to 6.45 mm without reducing the size of the exposed thermal pad and ensuring optimal heat dissipation. In addition, the exposed thermal pad has a nickel, nickel-phosphorus (NiNiP) plating, as opposed to tin (Sn) plating from existing TSC package solutions, which is critical to preserving the post-reflow surface planarity of the exposed pad and ensuring thermally efficient and reliable attachment to the thermal interface material (TIM).

    Enabled by over 20 years of SiC technology innovation leadership, Navitas’ GeneSiC™ ‘trench-assisted planar SiC MOSFET technology’ offers up to 20% lower on-resistance under in-circuit operation at high temperatures compared to competition and superior switching figure-of-merits which result in the lowest power losses across a wider operating range. All GeneSiC™ SiC MOSFETs have the highest-published 100%-tested avalanche capability, excellent short-circuit withstand energy, and tight threshold voltage distributions for easy paralleling.

    The initial HV-T2PaK portfolio includes 1200 V SiC MOSFETs with on-resistance ratings ranging from 18 mΩ to 135 mΩ and 650 V SiC MOSFETs with on-resistance ratings ranging from 20 mΩ to 55 mΩ. Lower on-resistance (<15 mΩ) SiC MOSFETs in HV-T2PaK package will be announced later in 2025.

    Nexperia Launches Automotive-Qualified SiC MOSFETs with Industry-Leading RDS(on) Stability for Next-Gen EV Power Systems

    2 Min Read

    Nexperia announced a range of highly efficient and robust automotive qualified silicon carbide (SiC) MOSFETs with RDS(on) values of 30, 40 and 60 mΩ. These devices (NSF030120D7A0-QNSF040120D7A1-QNSF060120D7A0-Q), which deliver industry-leading figures-of-merit (FoM), were previously offered in industrial grade and have now been awarded AEC-Q101 certification.

    This makes them suitable for automotive applications like onboard chargers (OBC) and traction inverters in electric vehicles (EV) as well as for DC-DC converters, heating ventilation and air-conditioning systems (HVAC). These switches are housed in the increasingly popular surface mounted D2PAK-7 package which is more suitable for automated assembly operations than through-hole devices.

    RDS(on) is a critical performance parameter for SiC MOSFETs as it impacts conduction losses. However, concentrating on the nominal value, neglects the fact that it can increase by more than 100% as device operating temperatures rise, resulting in considerable rise of conduction losses. The temperature stability is even more critical when SMD package technologies are used compared to through-hole technology since devices are cooled through the PCB.

    Nexperia identified this as a limiting factor in the performance of many currently available SiC devices and leveraged the features of its innovative process technology to ensure that its new SiC MOSFETs offer industry-leading temperature stability, with the nominal value of RDS(on) increasing by only 38% over an operating temperature range from 25 °C to 175 °C. This feature enables customers to address higher output power in their applications achieved with a higher nominal 25°C rated RDS(on) from Nexperia compared to other vendors without sacrificing performance.

    “This feature allows to get more power out of the selected Nexperia SiC MOSFET devices compared to similarly rated RDS(on) devices from other vendors, delivering a clear cost advantage for customers on semiconductor level. Additionally, relaxed cooling requirements, more compact passive components, and higher achievable efficiency allow customers more degrees of freedom in their design and lower total cost of ownership. We’re especially excited that these products are now available for the automotive market, where their performance and efficiency benefits can make a real difference in next-generation vehicle designs”, says Edoardo Merli, SVP and Head of Business Group Wide Bandgap, IGBT & Modules (WIM).

    Nexperia is planning to release automotive-qualified versions of its 17 mΩ and 80 mΩ RDS(on) SiC MOSFETs in 2025.

    WeEn Unveiled Thermally Efficient TSPAK SiC Devices at PCIM 2025

    2 Min Read

    WeEn Semiconductors showcased its silicon carbide (SiC) MOSFETs and Schottky Barrier Diodes (SBDs) in highly thermally efficient TSPAK packages at this year’s PCIM Expo conference and trade fair. The new packages enable engineers to improve efficiency, reduce form factors, extend reliability and lower EMI across a variety of high-power applications.

    Providing effective heat dissipation from a thermal pad on the surface of the SiC device rather than via a PCB substrate, the company’s top-side cooling TSPAK technologies can reduce J-A (junction-to-ambient) thermal resistance by up to 16% compared to conventional devices. As a result, the packages help to simplify thermal management design, lower losses and increase power density.

    By minimizing or eliminating the need for complex PCB cooling, TSPAK devices reduce component count and drive down system costs. In addition, the ability to support a greater number of power cycle extends reliability, while reduced EMI helps engineers to simplify system EMC compliance. EMI reduction derives from the fact that the circulating current that creates the magnetic field is no longer blocked by the thermal vias necessary in conventional bottom-side cooling designs and can return to the source directly, minimizing magnetic interference. 

    WeEn’s TSPAK SiC technologies are ideally suited to on-board chargers and high-voltage-to-low-voltage DC-DC converters in electric vehicles (EVs), automotive HVAC compressors, vehicle charging stations, photovoltaic (PV) renewable energy systems and power supplies for computing and telecom servers. TSPAK MOSFETs offer voltage ratings from 650 V to 1700 V and on resistance (RDS(ON)) ratings from 20 to 150mΩ. TSPAK SBDs are available with voltages from 650 V to 1200 V and current ratings of 10 A to 40 A. 

    All products are available in industrial grade and automotive grade variants.

    Cambridge GaN Devices (CGD) announced that Inventchip, a leading provider of SiC power devices and IC solutions headquartered in Shanghai, has successfully demo’d a 2.5 kW GaN-based CCM totem-pole PFC reference design using CGD’s ICeGaN® gallium nitride ICs. A key feature is ease-of use. ICeGaN ICs integrate interface circuitry and protection on the same GaN die as the HEMT. Therefore, any standard driver IC can be used. The Inventchip IVCC1104 totem pole PFC controller IC is also simple to use with no programming required. It offers optimized AC zero-crossing control, low THD and high robustness against AC disturbance.

    DI CHEN | DIRECTOR, TECHNICAL MARKETING AND BUSINESS DEVELOPMENT, CGD
    “Inventchip had an existing 2.5kW TPPFC reference design based on its controller and gate drivers using SiC MOSFETs in TO-247 packages. To evaluate the performance of GaN instead, Inventchip designed a TO-247 adapter board using our P2 25mΩ ICeGaN ICs and the ICeGaN design works perfectly without any modification of their circuits. It has demonstrated that the ICeGaN can significantly shorten the learning curve and allow engineers to bring new product faster to market.”

    DR. ZHONG YE |CTO , INVENTCHIP
    “By using a TO247-4 adapter board to solder on a DFN-packaged ICeGaN device for a quick test on our EVM, despite the relatively long gate drive path and the extended drive power supply trace, the board was powered up successfully at the first shot with clean switching waveform. No abnormalities or shoot-through was observed from no-load to full-load conditions. The GaN’s performance is very impressive. The CGD GaN device has proven to be very noise-immune, user-friendly and highly efficient.”

    Having proved its efficiency and power density in low power charger designs, GaN is now being adopted by makers of server and data centre PSUs, inverters, industrial brick DC/DC converters and LED drivers.

    Infineon has sold well over 70 million EasyPACK modules with various chipsets for a wide range of industrial and automotive applications. With the introduction of the CoolGaN power semiconductors in this package, Infineon is now expanding the application range of GaN as its use creates more demand into very high kilowatt applications.

    The EasyPACK series leverages Infineon’s PressFIT contact technology, which ensures highly reliable and durable electrical connections between the module and the PCB. By utilizing a cold-welding process, PressFIT delivers gas-tight, solder-free joints that guarantee long-term mechanical stability and electrical conductivity, even under demanding thermal and mechanical conditions. This advanced design reduces manufacturing time and eliminates potential solder-related defects, offering a robust solution for high-reliability applications. Additionally, with its compact design, EasyPACK modules occupy up to 30 percent less PCB surface area than other conventional discrete layouts, resulting in a very cost-effective solution.

    The newest 650 V CoolGaN generation provides increased performance and figures of merit. Infineon’s benchmark data shows that CoolGaN Transistor 650 V G5 products provide up to 50 percent lower energy stored in the output capacitance (E oss), up to 60 percent improved drain-source charge (Q oss) and up to 60 percent lower gate charge (Q g). Combined, these features result in increased efficiencies in both hard- and soft-switching applications.

    This leads to a significant reduction in power loss compared to traditional silicon technology, ranging from 20 to 60 percent depending on the specific use case. The CoolGaN Transistor 650 V G5 product family offers a wide range of R DS(on) package combinations. Ten R DS(on) classes are available in various SMD packages, such as ThinPAK 5×6, DFN 8×8, TOLL and TOLT. All products are manufactured on high-performance 8-inch production lines in Villach (Austria) and Kulim (Malaysia). Target applications range from consumer and industrial switched-mode power supply (SMPS) such as USB-C adapters and chargers, lighting, TV, data center, and telecom rectifiers to renewable energy and motor drives in home appliances.

    Infineon will showcase the EasyPACK modules with CoolGaN at PCIM 2025 in Nuremberg at the Infineon booth in Hall 7, Booth 470. Further information is available here.
