    1200V SiC MOSFET Targets Industrial and Automotive Market

    05/19/2020

    Alpha and Omega Semiconductor Limited (AOS) announced the release ofthe new 1200V silicon carbide (SiC) aSiC MOSFET technology platform. Specifically targeting the industrial and automotive market, this next-generation technology will enable customers to achieve higher levels of efficiency and power density compared to existing silicon solutions.

    Optimized for minimizing both AC and DC power losses through a low gate resistance (RG) design combined with the low increase in on-resistance (RDS,ON) over temperature, the aSiC technology can achieve the highest efficiencies across a wide range of application switching frequencies and temperatures.  This higher efficiency can result in significantly reduced system costs and total bill-of-materials for the many industrial uses, including solar inverters, UPS systems, and EV inverter and charging systems.

    The first product release for this new platform is the AOK065V120X2, a 1200V 65mWSiC MOSFET available in a TO-247-3L package.  For ease of use, the AOK065V120X2 is designed to be driven with a -5V/+15V gate drive, allowing the broadest compatibility with existing high voltage IGBT and SiC gate drivers.  Operation with a unipolar drive is also possible with optimized system design.  Additional benefits of the aSiC platform is a robust UIS capability, enhanced short circuit performance, and a high maximum operating temperature of 175oC.

    The aSiC MOSFET portfolio will expand later this year to include a broader range of on-resistance and additional package options with full AEC-Q101 qualification.

    Pricing and Availability

    As part of the first wave release, the AOK065V120X2 (1200V 65mOhm TO-247-3L) is immediatelyavailable for production quantities.
