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 Ron degradation over time. A new structure of a SBD-embedded MOSFET has been proposed that prevents the current conduction through its intrinsic body diode. A low RonA 1.2kV class SBD-embedded SiC MOSFET has been realized that improves its reliability by optimizing the SBD structure.
