The junction temperature range extends to 175°C, which is the ceiling for the heatsink design — the TO-220AC tab must be thermally coupled to a heatsink sized for 12 A continuous conduction at the ambient under-hood temperature. Reverse leakage at 650 V is 120 µA — negligible at 25°C but rises with junction temperature; the thermal budget should account for leakage at the 175°C endpoint. ## Switching speed and capacitive charge The diode is rated Fast Recovery ≤500 ns at >200 mA, but as a SiC Schottky it is a majority-carrier device with no reverse recovery charge — the 500 ns figure is a classification label, not a switching limit. The real switching loss driver is the junction capacitance: 530 pF at 0 V, 1 MHz. In a hard-switched PFC at 100 kHz, the capacitive turn-on loss is the number to budget, not a recovery tail.","metaTitle":"STPSC12C065DY SiC Schottky Diode, 650 V, 12 A, TO-220AC","metaDescription":"STPSC12C065DY automotive SiC Schottky diode, 650 V, 12 A, AEC-Q101 qualified, TO-220AC.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101, ECOPACK®2","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"ECOPACK®2","Package":"Tube","Technology":"SiC (Silicon Carbide) Schottky","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"TO-220-2","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPSC12","Capacitance @ Vr, F":"530pF @ 0V, 1MHz","Supplier Device Package":"TO-220AC","Current - Reverse Leakage @ Vr":"120 µA @ 650 V","Voltage - DC Reverse (Vr) (Max)":"650 V","Current - Average Rectified (Io)":"12A","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.75 V @ 12 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1700","priceTiers":[{"qty":1,"price":"$4.42000","currency":"USD"},{"qty":10,"price":"$3.97200","currency":"USD"},{"qty":100,"price":"$3.25450","currency":"USD"},{"qty":500,"price":"$2.77052","currency":"USD"},{"qty":1000,"price":"$2.72965","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c9f5052f5804cad92a2ccc221b71d964.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPSC12C065DY/alternatives.json"},"ai":{"faq":[{"question":"Can STPSC12C065DY replace STPSC12C065?","answer":"The STPSC12C065DY is the automotive-grade variant of the base STPSC12C065.
