650V Silicon Carbide (SiC) Schottky Diode Wolfspeed 650V Silicon Carbide (SiC) Schottky Diode features zero reverse recovery current and zero reverse recovery voltage. Schottky diode is a semiconductor diode formed by the junction of a semiconductor with a metal. The device is ideal for switch mode power supplies (SMPS), boost diodes in PFC or DC/DC stages, AC/DC converters, and free-wheeling diodes in inverter stages. Wolfspeed Schottkey Diode provides optimised fast switching and reduces heat-sink requirements. This performance is achieved by high-frequency operation and temperature-independent switching behaviour.
