That combination makes it a candidate for on-board charger PFC stages, DC-DC converter. ## Forward drop and capacitance — what the BOM needs to budget Maximum forward voltage is 1.5 V at 20 A, 25°C. That 30 W conduction loss at full rated current sets the heatsink requirement — a TO-220AC bolted to a properly sized aluminium extrusion handles it, but the thermal interface matters. Junction-to-case thermal resistance is not listed here; the designer should pull the full thermal model from the datasheet. The 1650 pF junction capacitance at 0 V, 1 MHz is the charge the gate driver sees each switching cycle — a SiC Schottky's capacitive turn-on loss is lower than a silicon fast diode's reverse recovery loss, but it is not zero. STMicroelectronics lists the STPSC20H12DY as Active.","metaTitle":"STPSC20H12DY SiC Schottky Diode, 1200 V, 20 A, AEC-Q101","metaDescription":"STPSC20H12DY silicon carbide Schottky diode, 1200 V reverse voltage, 20 A average rectified current, zero reverse recovery time.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"No Recovery Time > 500mA (Io)","Series":"Automotive, AEC-Q101, ECOPACK®2","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":"STPSC20","Capacitance @ Vr, F":"1650pF @ 0V, 1MHz","Supplier Device Package":"TO-220AC","Reverse Recovery Time (trr)":"0 ns","Current - Reverse Leakage @ Vr":"120 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"20A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"1.5 V @ 20 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.4500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/29bdf6761c3a1049cf9bd443847b23a4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STPSC20H12DY?","answer":"Zero nanoseconds. As a silicon carbide Schottky diode, the STPSC20H12DY has no reverse recovery charge — it switches off immediately when the voltage reverses, with no stored minority carriers to sweep out."},{"question":"Can STPSC20H12DY be used in automotive applications?","answer":"Yes.
