This work reports an SiC-MOSFET which replaces a part of the channel resistance with an additional embedded resistance, called a source resistance ( R s ). MOSFETs with R s have higher resistance during short circuit compared with MOSFETs without R s and suppress short-circuit currents. An improvement of the trade-off relationship between short-circuit capability and on-resistance was obtained with MOSFETs including embedded R s .
