onsemi released 2nd generation of 1200 V silicon carbide (SiC) MOSFET, named M3S, S means switching. M3S−series is focused on improvement in switching performance than 1st generation of 1200 V SiC MOSFET, in addition to the reduction in specific resistance, RSP, defined as RDS(ON)*Area. M3S is optimized for providing the better performance in high power applications for industrial power system such as solar inverters, ESS, UPS and off−board electric vehicle chargers. It can help designers to increase the switching frequency with high system efficiency. This application note describes the key characteristics of M3S, how much improved compare to Gen 1 and provides useful design tips.
