That combination — SiC Schottky at 650 V — puts it squarely in power-factor-correction stages, high-frequency SMPS outputs, and on-board charger circuits where reverse-recovery losses in a standard ultrafast diode would eat into efficiency. The 1.75 V forward drop at 12 A is the conduction-loss figure you budget for in the thermal model. At 12 A continuous, that's 21 W of forward loss before switching losses — the TO-220AC package needs a heatsink sized for that dissipation. ## 175°C junction — thermal headroom for compact builds Rated junction temperature spans -40°C to 175°C. The 175°C upper limit is wider than a typical 150°C Si diode, which gives you extra margin in a tightly-packed PFC stage or a hot engine-bay environment. The reverse leakage at 650 V is 120 µA — that figure climbs with temperature, so at 150°C junction the leakage contribution to the thermal budget needs checking.","metaTitle":"STPSC12H065D SiC Schottky Diode, 650 V, 12 A, TO-220AC","metaDescription":"STPSC12H065D Silicon Carbide Schottky diode, 650 V reverse voltage, 12 A average rectified current, 1.75 V forward drop at 12 A.","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","Diode Type":"Silicon Carbide Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-2","Product Status":"Active","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":"$4.3300","priceTiers":[{"qty":1,"price":"$4.33000","currency":"USD"},{"qty":10,"price":"$3.89000","currency":"USD"},{"qty":100,"price":"$3.18710","currency":"USD"},{"qty":500,"price":"$2.71314","currency":"USD"},{"qty":1000,"price":"$2.67312","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b53bb124e89f50d0b0da79a29186ced9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPSC12H065D/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPSC12H065D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPSC12H065D when reusing this data.
