The SiC technology gives it near-zero reverse recovery charge — the fast recovery spec (≤ 500 ns at > 200 mA) is conservative; in practice the switching losses are dominated by the junction capacitance, not stored charge. ## Conduction loss and thermal budget Forward voltage is 1.75 V max at 12 A and 25 °C junction — that is the worst-case conduction loss floor for a 12 A load. At 12 A the die dissipates about 21 W; the TO-220AC package with a proper heatsink keeps the junction below 175 °C, but the derating curve matters: above 100 °C the Vf rises and the thermal resistance of the mounting surface becomes the limit. The 600 pF capacitance at 0 V (1 MHz) is typical for a 12 A SiC die — it sets the switching loss at high frequency and the driver's peak current requirement. ## Automotive grade and AEC-Q101 qualification The ECOPACK®2 compliance covers the RoHS and halogen-free requirements for automotive supply chains.","metaTitle":"STPSC12H065DY SiC Schottky Diode, 650V 12A, AEC-Q101","metaDescription":"STPSC12H065DY automotive SiC Schottky diode: 650V, 12A, 1.75V Vf at 12A, AEC-Q101 qualified.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q101, ECOPACK®2","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPSC12","Capacitance @ Vr, F":"600pF @ 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":"$4.4900","priceTiers":[{"qty":1,"price":"$4.54000","currency":"USD"},{"qty":10,"price":"$4.07500","currency":"USD"},{"qty":100,"price":"$3.33860","currency":"USD"},{"qty":500,"price":"$2.84210","currency":"USD"},{"qty":1000,"price":"$2.80018","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2f58cae968426a4c611ba468e919c6f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPSC12H065DY/alternatives.json"},"ai":{"faq":[{"question":"Is STPSC12H065DY obsolete?","answer":"Yes, STMicroelectronics lists the STPSC12H065DY as Obsolete."},{"question":"What is the closest pin-compatible alternative to STPSC12H065DY?","answer":"No official cross-reference or second-source part is listed on the lifecycle record.
