onsemi NVBG1000N170M1 Silicon Carbide (SiC) MOSFET is a 1700V M1 planar device optimized for fast switching applications. Planar technology works reliably with negative gate voltage drives and turns off spikes on the gate. This N-channel ElteSiC MOSFET delivers optimum performance when driven with a 20V gate drive but also works well with an 18V gate drive.
