As digitalization, urbanization, and the rise of electro-mobility continue to shape the rapidly evolving world, the demand for power consumption is reaching unprecedented levels. Acknowledging energy efficiency as an important concern, Infineon Technologies AG addresses these megatrends with its silicon carbide (SiC) CoolSiC™ MOSFET 650 V in TO leadless (TOLL) packaging. The new SiC MOSFETs are enhancing Infineon’s comprehensive CoolSiC portfolio and are optimized for the lowest losses, the highest reliability, and ease-of-use in applications such as SMPS for servers, telecom infrastructure as well as energy storage systems and battery formation solutions.
The CoolSiC 650 V high-performance trench-based power SiC MOSFETs are offered in a very granular portfolio to best suit different target applications. The new family comes in a JEDEC-qualified TOLL package featuring a low parasitic inductance, allowing for higher switching frequency, reduced switching losses, good thermal management, and automated assembly. The compact form factor enables efficient and effective usage of the board space, empowering system designers to achieve exceptional power density.
The CoolSiC MOSFETs 650 V showcase remarkable reliability even in harsh environments, making them an ideal choice for topologies with repetitive hard commutation. The inclusion of the innovative .XT interconnect technology further enhances the devices’ thermal performance by reducing the thermal resistance (R th) and thermal impedance (Z th). In addition, the new devices feature a gate threshold voltage (V GS(th)) greater than 4 V for robustness against parasitic turn-on, a robust body diode, and the strongest gate oxide (GOX) in the market resulting in extremely low FIT (failures in time) rates.
While a cut-off voltage (V GS(off)) of 0 V is generally recommended to simplify the driving circuit (unipolar driving), the new portfolio supports a wide driving interval of V GS voltage within the range of -5 V (turn-off) to 23 V (turn-on). This ensures ease-of-use and compatibility with other SiC MOSFETs and standard MOSFET gate-driver ICs. This is paired with higher reliability, reduced system complexity, and the enablement of automated assembly, reducing system and production costs and accelerating time-to-market.

NoMIS Power has achieved its latest major milestone with an award from the U.S. Air Force Research Laboratory (AFRL) to develop rugged Silicon Carbide (SiC) power devices to support the electrical power systems of aircraft.
NoMIS Power will develop 1200 V SiC power semiconductor devices (PSDs) through the award. The focus will be on metal-oxide-semiconductor field-effect transistors (MOSFETs) with enhanced operational lifetime as well as improved on-state and off-state efficiency at operating temperatures, resulting in lower losses for power electronics engineers to manage.
Solid-state power controllers within aircraft electrical power distribution systems require low on-state losses to enable passive cooling, as well as surge current and voltage overshoot protection during system start-up and fault interrupt. The proposed 1200 V SiC MOSFETs from NoMIS Power will provide airframers and system builders/integrators with the necessary PSD chips capable of high efficiency, long short-circuit withstand time (SCWT), and operational ruggedness for nominal and transient conditions. Moreover, the 1200 V rating will not only support current-generation aircraft utilizing 270 VDC architecture, but also aircraft operating with a +/- 270 VDC (i.e. 540 VDC rail-to-rail) architecture, as well.
NoMIS Power overcomes the limitations of commercial-off-the-shelf (COTS) Si and SiC-based PSDs via a novel SiC device design that is achievable using disruptive manufacturing techniques. As a result, NoMIS SiC devices can withstand higher voltage spikes and current surges during harsh operating conditions, enabling longer power management product lifetime through superior reliability and ruggedness.
Announcing the new award, NoMIS Power CEO Dr. Adam Morgan said, “Our team is very excited to get the opportunity to support strategic groups working to improve the capabilities of our armed forces. We are confident this novel SiC device technology will also have a significant impact on other critical technology markets, such as electric vehicles and grid infrastructure. These efforts will directly support our company’s near-term product launch of next-generation SiC devices.”

Transphorm, Inc. responded to the recent news regarding China export restrictions. Late Monday, July 3, 2023, China’s Ministry of Commerce stated that it will restrict the exports of materials related to two metals used in semiconductor manufacturing: gallium and germanium. Gallium nitride (GaN) wafer materials are listed as being affected by these regulations.
Transphorm manufactures high voltage GaN power semiconductors. Trimethylgallium (TMGa) is used to produce the GaN. The company confirmed that its primary TMGa suppliers are not based in China and that suppliers have confirmed to be well-positioned to meet forecasted demand. Transphorm is therefore securely positioned to continue manufacturing and supplying its GaN devices without interruption.
Transphorm also explained gallium is generally a byproduct resulting from refinement processes used to produce popular metals such as aluminum from bauxite ore. Aluminum is produced in numerous countries such as Australia, Brazil, India, Jamaica, and the United States among others.
Transphorm will continue to the monitor the situation as necessary but sees no direct impact on its current operations. Nor does the company see long-term sourcing issues.
