One of the issues of SiC MOSFET is the reliability of its intrinsic body diode when used as a free-wheeling diode (FWD). The reverse current through the SiC MOSFET may cause 4 â á degradation over time. A new structure of a SBD-embedded MOSFET has been proposed that prevents the current conduction through its intrinsic body diode.

Among SiC MOSFET structures, the trench MOSFET has a low channel resistance thanks to its high channel density and mobility[5, 6]. However, in a high-voltage SiC MOSFET (a voltage of 3.3 kV or above), the channel resistance does not have a significant effect because of the high drift resistance. In addition, at high voltages, the trench MOSFET ...
