Each diode handles 6 A average rectified current, giving a total 12 A output for a PFC boost or inverter freewheeling leg. The 650 V blocking voltage provides a 1.6× derating margin over a 400 V DC bus, which is the standard for single-phase and three-phase PFC stages in industrial power supplies and motor drives. The fast recovery spec (≤500 ns at >200 mA) is typical for SiC Schottky — there is no reverse recovery charge to sweep out, so switching losses are near-zero. This lets the designer push the switching frequency above 100 kHz without the thermal penalty a silicon ultrafast diode would incur. Forward voltage is 1.75 V maximum at 6 A per diode. At full load each diode dissipates about 10.5 W; the common-cathode pair totals 21 W. Reverse leakage is 60 µA at 650 V, which is negligible at room temperature but rises with junction temperature. Even at 175°C it stays well below the leakage of a comparable silicon fast-recovery diode, keeping standby losses low in lightly loaded conditions. The base product number is STPSC12, which covers a family of 650 V SiC Schottky diodes in various current ratings and packages. The CT suffix denotes the common-cathode dual-diode configuration in TO-220. ## Package and mounting — TO-220 through-hole for heatsink attachment The TO-220-3 through-hole package (supplier device package TO-220) has a metal tab for bolting to a heatsink. The shipping medium is Tube, which is the standard for through-hole power devices in TO-220.","metaTitle":"STPSC12H065CT SiC Schottky Diode, 650 V, 12 A, TO-220-3","metaDescription":"STPSC12H065CT Silicon Carbide Schottky diode, 650 V reverse, 12 A total (2x6 A common cathode), fast recovery ≤500 ns, TO-220-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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-220-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPSC12","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"60 µA @ 650 V","Voltage - DC Reverse (Vr) (Max)":"650 V","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"1.75 V @ 6 A","Current - Average Rectified (Io) (per Diode)":"6A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b37a003d152e0b5579170638e0c03e75.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STPSC12H065CT?","answer":"For a pin-compatible replacement, compare the 650 V, 12 A common-cathode SiC Schottky diodes from other manufacturers — the TO-220-3 footprint is standard, but confirm the forward voltage and junction temperature rating against your thermal budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPSC12H065CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPSC12H065CT when reusing this data.
