SiC FETs

High-Performance SiC FETs

The UJ3C, UF3C/SC or new Gen 4 UJ4C FET series delivers best-in-class switching speed, lower switching losses, higher efficiency, standard thru-hole (including Kelvin) and surface mount packages, with excellent cost effectiveness. The high-performance FETs are based on a unique cascode configuration, where a high performance SiC fast JFET is co-packaged with a cascode optimized Si-MOSFET to produce the only standard gate drive SiC device in the market today. All devices are AEC-Q101 qualified.
