It is designed for output rectification, freewheeling, and polarity protection in switch-mode power supplies and DC-DC converters. The 60 V reverse voltage gives comfortable margin on a 48 V bus or a 24 V industrial rail with transients. The 3 A average current rating covers most point-of-load and auxiliary supply outputs up to about 36 W at 12 V. ## Forward drop and thermal budget Forward voltage is specified at 620 mV maximum at 3 A. That is a low drop for a 60 V Schottky in this current class, which directly reduces conduction loss and keeps the junction cooler at full load. Just remember that reverse leakage climbs with temperature; at 150°C junction the 150 µA at 60 V (25°C figure) will be higher, so budget standby loss accordingly. The DO-221AA / SMB Flat Leads package is a surface-mount, low-profile variant of the standard SMB. It uses the same 5.3 mm x 3.5 mm footprint as a conventional SMB but with flat leads that reduce height and improve solder-joint inspection visibility. No special thermal pad or via array needed — the SMB footprint with standard copper land pattern handles the 3 A continuous current if the PCB copper is adequate.","metaTitle":"STPS3L60UF Schottky Diode, 60 V, 3 A, SMB Flat Leads","metaDescription":"STPS3L60UF Schottky rectifier: 60 V reverse voltage, 3 A average current, 620 mV forward drop at 3 A, 150°C Tj max, SMBflat package.","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":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"DO-221AA, SMB Flat Leads","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS3","Capacitance @ Vr, F":"-","Supplier Device Package":"SMBflat","Current - Reverse Leakage @ Vr":"150 µA @ 60 V","Voltage - DC Reverse (Vr) (Max)":"60 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"620 mV @ 3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5ec30811a5b83c478ef68f4d868991dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS3L60UF/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STPS3L60UF?","answer":"Within the same STPS3 family, the STPS3L60 is a through-hole (DO-201AD) variant with the same 60 V, 3 A ratings but a different footprint. For a surface-mount alternative, parts like the STPS3L60S (SMC package) or the STPS3L60U (SMB package) share the same die and ratings but differ in package outline. Pin compatibility depends on the specific package — the SMBflat footprint is unique to the UF suffix."},{"question":"What is STPS3L60UF's listed speed?","answer":"The STPS3L60UF is a Schottky diode, so it has fast recovery characteristics typical of Schottky rectifiers — recovery time is inherently below 500 ns at forward currents above 200 mA. This makes it suitable for high-frequency switching up to several hundred kilohertz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS3L60UF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS3L60UF when reusing this data.
