The TO-220-3 through-hole package suits socketed or bolted-down mounting on a heatsink, typical in industrial power converters, battery chargers, and welding equipment where the pair shares the cathode rail. ## Obsolete — sourcing through surplus distribution For a BOM that calls out this exact order code, procurement now depends on the surplus and independent-distribution channel. ## Fast recovery rating — switching context Listed as Fast Recovery ≤500 ns at >200 mA, this Schottky recovers quickly enough for line-frequency and moderate-frequency rectification — think 50/60 Hz mains rectifiers or 100–200 kHz SMPS outputs where the diode's junction capacitance and reverse recovery are not the limiting factors. It is not a hyper-fast SiC or GaN companion; the 500 ns ceiling is a recovery class flag, not a switching-speed differentiator. ## 150°C junction limit and thermal design Maximum junction temperature is 150°C. With 25 A per diode and 730 mV forward drop, each leg dissipates about 18 W at full rated current. The TO-220 case relies on a good thermal interface to a heatsink — without one, junction temperature exceeds the limit well below the 25 A rating. The 200 µA reverse leakage at 100 V is nominal at 25°C but climbs sharply with temperature, so derating for hot environments is mandatory.","metaTitle":"STPS50U100CT Schottky Diode, 100V 25A x2, TO-220-3, Obsolete","metaDescription":"STPS50U100CT dual Schottky rectifier, 100V Vr, 25A per diode, 730mV Vf at 25A, TO-220-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS50","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"200 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"730 mV @ 25 A","Current - Average Rectified (Io) (per Diode)":"25A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/303f99bf11318c46015c01f446cd70b7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS50U100CT/alternatives.json"},"ai":{"faq":[{"question":"Is the STPS50U100CT equivalent to the MBR20100?","answer":"The MBR20100 is a single 20 A, 100 V Schottky diode in a TO-220 package — it is a different part.
