onsemi M3S 1200V Silicon Carbide (SiC) MOSFETs are optimized for fast switching applications. The planar technology works reliably with negative gate voltage drive and turn-off spikes on the gate. The onsemi M3S 1200V MOSFETs provide optimum performance when driven with an 18V gate drive but also works well with a 15V gate drive. The M3S offers low switching losses and is housed in a TO247-4LD package for low common source inductance.
