It is AEC-Q101 qualified, making it suitable for automotive power-supply and reverse-protection circuits where the OEM auditor expects a PPAP-ready device. Reverse leakage is 50 µA at 45 V rated reverse voltage — this leakage doubles roughly every 10 °C above 25 °C, so the thermal pad area on the TO-277A (SMPC) package must be sized to keep junction temperature below 150 °C under sustained load. The series is ECOPACK®2, RoHS3 compliant, with no restricted substances in the junction coating or lead finish.","metaTitle":"STPS1045SFY Schottky diode, 45 V, 10 A, AEC-Q101, TO-277A","metaDescription":"STPS1045SFY Automotive Schottky rectifier: 45 V reverse, 10 A forward, AEC-Q101 qualified, TO-277A (SMPC) surface-mount, 175 °C junction.","metaKeywords":null},"attributes":{"series":"ECOPACK®2","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"ECOPACK®2","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Surface Mount","Qualification":"AEC-Q101","Package / Case":"TO-277, 3-PowerDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS1045","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-277A (SMPC)","Current - Reverse Leakage @ Vr":"50 µA @ 45 V","Voltage - DC Reverse (Vr) (Max)":"45 V","Current - Average Rectified (Io)":"10A","Operating Temperature - Junction":"-40°C ~ 175°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7400","priceTiers":[{"qty":1,"price":"$0.78000","currency":"USD"},{"qty":10,"price":"$0.68700","currency":"USD"},{"qty":100,"price":"$0.52700","currency":"USD"},{"qty":500,"price":"$0.41658","currency":"USD"},{"qty":1000,"price":"$0.34388","currency":"USD"},{"qty":6000,"price":"$0.34388","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b124305bbf0426eee3ca53e91221e6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS1045SFY/alternatives.json"},"ai":{"faq":[{"question":"Is STPS1045SFY automotive grade and AEC-Q101 qualified?","answer":"Yes, it is listed as Automotive grade and is AEC-Q101 qualified, which means it meets the stress and reliability tests required for automotive applications including PPAP documentation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS1045SFY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS1045SFY when reusing this data.
