The fast-recovery characteristic (≤ 500 ns) makes it suitable for line-frequency rectification, output OR-ing, and moderate-speed power supplies where Schottky's low Vf and fast switching reduce losses compared to ultrafast silicon diodes. ## 150 V blocking, 40 A per leg — the thermal and loss budget At 150 V reverse and 150°C junction, reverse leakage is 30 µA typical — a figure that rises with temperature, so the thermal design must account for leakage-induced self-heating at high ambient. The common-cathode pair shares the same tab (pin 2), simplifying the PCB layout for a center-tapped secondary or a full-wave rectifier — the two anodes are independent, so each leg can be paralleled for higher current or used as separate rectifiers sharing a common return.","metaTitle":"STPS80150CW Schottky Diode, 150 V, 40 A, TO-247-3","metaDescription":"STPS80150CW dual Schottky rectifier, 150 V reverse, 40 A per diode, common cathode, TO-247-3.","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":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-247-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS80150","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-247-3","Current - Reverse Leakage @ Vr":"30 µA @ 150 V","Voltage - DC Reverse (Vr) (Max)":"150 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"840 mV @ 40 A","Current - Average Rectified (Io) (per Diode)":"40A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8e6fbd8ba238cf22689dae6bb82d6595.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS80150CW/alternatives.json"},"ai":{"faq":[{"question":"Does STPS80150CW have a common cathode configuration?","answer":"Yes, the two Schottky diodes share a common cathode (pin 2 in the TO-247-3 package).
