STPSC406 is an ultrahigh performance power Schottky diode from ST. It is manufactured using a silicon carbide substrate. The wide bandgap material allows the design of a Schottky diode structure with a 600 V rating. Due to the Schottky construction no recovery is shown at turn-off and ringing patterns are negligible. The minimal capacitive turn-off behavior is independent of temperature. ST SiC diodes will boost the performance of PFC operations in hard switching conditions.
