STPSC8H065C 650 V power Schottky silicon carbide diode Datasheet - production data Description The SiC diode is an ultrahigh performance power A1 Schottky diode. It is manufactured using a silicon K carbide substrate. The wide band gap material A2 allows the design of a Schottky diode structure with a 650 V rating. Due to the Schottky construction, no recovery is shown at turn-off and ringing patterns are negligible. The minimized capacitive charge at turn-off behavior is independent of temperature. A2 Especially suited for use in interleaved or bridge- K A1 less topologies, this dual-diode rectifier will boost TO-220AB the performance in hard switching conditions. Its STPSC8H065CT high forward surge capability ensures a good robustness during transient phases. Table 1.
