As a SiC Schottky, it offers near-zero reverse recovery charge, which cuts switching losses in continuous-conduction-mode PFC stages, flyback output rectifiers, and secondary-side freewheeling in telecom and server power supplies. ## 650 V blocking and 4 A forward — where it fits With a 650 V DC reverse voltage rating, this diode comfortably blocks the 400 V bus in a power-factor-correction stage with margin for transients. The 4 A average rectified current suits moderate-power designs — think 250 W to 500 W PFC boost stages or LLC converters. Reverse leakage is 40 µA at 650 V, a figure that stays low across temperature compared to silicon, keeping standby losses in check. ## 175°C junction — the SiC thermal advantage The -40°C to 175°C operating junction range is a hallmark of SiC. In a hot PFC stage or enclosed power supply, the higher Tj max means the diode can run hotter without needing a larger heatsink or forced air. This directly translates to board area savings or higher output power in the same footprint. The insulated TO-220AC package simplifies heatsink mounting — no isolation pad, reducing thermal resistance and assembly cost. ## Production status and supply STMicroelectronics lists the STPSC4H065DI as an active product.","metaTitle":"ST STPSC4H065DI SiC Schottky Diode, 650 V, 4 A, TO-220AC ins","metaDescription":"STMicroelectronics STPSC4H065DI Silicon Carbide Schottky diode, 650 V reverse voltage, 4 A average rectified current, TO-220AC insulated package, -40°C to","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-220-2 Insulated, TO-220AC","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPSC4","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC ins","Current - Reverse Leakage @ Vr":"40 µA @ 650 V","Voltage - DC Reverse (Vr) (Max)":"650 V","Current - Average Rectified (Io)":"4A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"1.75 V @ 4 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/afc3e1ca4b3978e724a3e2f687260d9f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPSC4H065DI/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STPSC4H065DI and STPSC4H065D?","answer":"The STPSC4H065DI uses the TO-220AC insulated package, while the STPSC4H065D uses the standard non-insulated TO-220AC."},{"question":"Is STPSC4H065DI RoHS compliant?","answer":"STMicroelectronics typically marks SiC Schottky diodes in the TO-220AC package as RoHS compliant and halogen-free.
