Loss-Comparison between SiC MOSFET and Si IGBT

Toshiba’s SiC MOSFET is intended for AC-DC converters, solar-powered inverters, and two-way DC-DC converters for UPS for industrial equipment. Compared with a 1200V Si IGBT (Insulated Gate-Type Bipolar Transistor) Toshiba’s 1200V SiC MOSFET offers higher switching speeds, lower ON-resistance, about a 77%[1] reduction in turn-OFF loss and about 76%[2] reduction in turn-ON loss, plus low-ON-voltage [3] in the drain-current range below 25A.
