It is classified as a Fast Recovery device (≤ 500 ns, > 200 mA), making it suitable for high-frequency rectification and freewheeling applications in power supplies and DC-DC converters. The 45 V reverse voltage rating sets the maximum blocking voltage; for a 24 V or 48 V bus, derating to 80% leaves adequate margin. The 10 A average rectified current is the DC output capability in a continuous conduction mode — a 5 A load leaves 50% headroom for surge events. The 600 mV forward drop at 10 A is typical for a 45 V Schottky at this current level; lower-drop alternatives exist but trade off reverse leakage. The 100 µA reverse leakage at 45 V is a maximum at 25°C; leakage doubles with every 10°C rise, so at 125°C junction it can approach several milliamps — factor this into standby power budgets.","metaTitle":"STPS1045FP Schottky Rectifier, 45V 10A, TO-220FPAC, Obsolete","metaDescription":"STPS1045FP Schottky diode, 45V reverse voltage, 10A average rectified current, 600mV forward drop, TO-220-2 Full Pack.","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","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-2 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS1045","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220FPAC","Current - Reverse Leakage @ Vr":"100 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Current - Average Rectified (Io)":"10A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"600 mV @ 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/59209b04ab77110ffe05fc05db620ca5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS1045FP/alternatives.json"},"ai":{"faq":[{"question":"Is STPS1045FP obsolete?","answer":"Yes, the STPS1045FP carries an Obsolete lifecycle status.
