STPSC806D 600 V power Schottky silicon carbide diode Features ■ No or negligible reverse recovery ■ Switching behavior independent of temperature ■ Particularly suitable in PFC boost diode function A Description K The SiC diode is an ultrahigh performance power Schottky diode. 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. May 2008 TO-220AC STPSC806D Table 1.
