The SiC Schottky technology eliminates reverse recovery charge, so the diode switches off with negligible current tail. This cuts switching losses in hard-switched topologies — boost PFC, half-bridge, and full-bridge converters — where a silicon ultrafast diode would add 50-100 ns of recovery loss per cycle. ## 175 °C junction — thermal headroom for sealed enclosures Rated junction temperature spans -40°C to 175°C, allowing the part to deliver full rated current in high-ambient environments without derating. The TO-247-3 package with a large copper tab conducts heat to the heatsink efficiently; the 300 µA reverse leakage at 600 V is typical for a 650 V SiC die at 25°C and rises with temperature, but the wide bandgap keeps it manageable up to 175°C.","metaTitle":"STPSC40065CW SiC Schottky Diode, 650 V, 20 A, TO-247-3","metaDescription":"STPSC40065CW SiC Schottky diode, 650 V reverse voltage, 20 A average rectified current per diode, common-cathode pair in TO-247-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"SiC (Silicon Carbide) Schottky","Mounting Type":"Through Hole","Package / Case":"TO-247-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPSC40065","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-247-3","Current - Reverse Leakage @ Vr":"300 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"650 V","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"1.7 V @ 20 A","Current - Average Rectified (Io) (per Diode)":"20A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.5100","priceTiers":[{"qty":1,"price":"$12.51000","currency":"USD"},{"qty":10,"price":"$11.02000","currency":"USD"},{"qty":100,"price":"$9.53050","currency":"USD"},{"qty":500,"price":"$8.63704","currency":"USD"},{"qty":1000,"price":"$7.92225","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/131ab612374e4ba5eab8e965dad80b69.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPSC40065CW/alternatives.json"},"ai":{"faq":[{"question":"Is STPSC40065CW equivalent to STPSC40065CT?","answer":"The STPSC40065CT is a different package variant (TO-220-3) of the same 650 V, 20 A SiC Schottky die.
