STPSC4H065 Datasheet 650 V, 4 A high surge silicon carbide power Schottky diode Features No reverse recovery charge in application current range Switching behavior independent of temperature High forward surge capability Insulated package TO-220AC Ins: Insulated voltage: 2500 V TO-220AC RMS TO-220AC ins. Typical package capacitance: 7 pF Power efficient product ECOPACK 2 compliant component DPAK Applications Switch mode power supply PFC DCDC converters LLC topologies Boost diode Description This 4 A, 650 V SiC diode is an ultrahigh performance power Schottky diode. It is manufactured using a silicon carbide substrate. The wide band gap material allows Product status 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 STPSC4H065 minimal capacitive turn-off behavior is independent of temperature. This STPSC4H065 is especially suited for use in PFC applications. This ST SiC Product summary diode will boost the performance in hard switching conditions. Its high forward surge Symbol Value capability ensures a good robustness during transient phases. I F(AV) 4 A V 650 V RRM T 175 C j(max.)
