UnitedSiC has introduced the Gen 4 UJ4C series of 750V SiC FETs for delivering breakthrough performance levels in automotive and industrial charging, telecom rectifiers, datacenter PFC DC-DC conversion, and renewable energy and energy storage applications. These new FETs offer best-in-class performance figures of merit (FoM) for lower conduction losses and increase efficiency at higher speed besides maintaining high levels of cost-effectiveness. The device is safety-driven with standard 0V to 12V or 15V gate drive voltage and delivers an excellent threshold noise margin maintained with true 5V threshold voltage.


With a built-in ESD protection clamp, the new SiC FETs can be operated from all the typical Si IGBT, Si MOSFET, and SiC MOSFET drive voltages. The UJ4C series is AEC-Q101 qualified, and they are packed in industry-standard TO247-3L and TO247-4L packages.


Features of UJ4C SiC FET Series

  • 750V VDS rating
  • Low RDS(on) from 18mohm to 60mohm
  • Excellent reverse recovery
  • Low body diode
  • Low gate charge
  • Low intrinsic capacitance
  • ESD protected, HBM class 2
  • Industry-standard through-hole and surface-mount packaging
