N-Channel SiC Power MOSFETs ROHM Semiconductor N-Channel Silicon Carbide (SiC) Power MOSFETs feature no tail current during switching, resulting in faster operation and reduced switching loss. Their low ON resistance and compact chip size ensure low capacitance and gate charge. These ROHM SiC Power MOSFETs exhibit minimal ON-resistance increases and provides greater package miniaturization. This provides more energy savings than standard Si devices, in which the ON-resistance can more than double with increased temperature.
