Its Schottky construction delivers a forward voltage of 820 mV at the full 2 A rated current, keeping conduction losses manageable in a compact footprint. Procurement must go through independent distribution or the surplus market. ## Ratings that define the fit The 150 V reverse voltage rating suits it for 12 V and 24 V DC rails with margin for transients. At 2 A average rectified current, it handles moderate loads like secondary-side rectification in a 15 W to 30 W offline supply. The 820 mV forward drop at 2 A is typical for a 150 V Schottky in this current class — expect slightly higher drop at elevated junction temperature, so derate the output current if the ambient is above 85°C. The DO-221AC SMA Flat Leads package is a surface-mount, low-profile variant of the standard SMA. It shares the same 2-pin footprint as a standard SMA but with flat leads for better solder wetting and visual inspection.","metaTitle":"STPS2150AFN Schottky Diode, 150 V, 2 A, SMA Flat Leads","metaDescription":"STPS2150AFN Schottky rectifier: 150 V reverse, 2 A average, 820 mV forward drop at 2 A.","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":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Schottky","Mounting Type":"Surface Mount","Package / Case":"DO-221AC, SMA Flat Leads","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS2150","Capacitance @ Vr, F":"-","Supplier Device Package":"SMAflat Notch","Current - Reverse Leakage @ Vr":"1.5 µA @ 150 V","Voltage - DC Reverse (Vr) (Max)":"150 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"175°C","Voltage - Forward (Vf) (Max) @ If":"820 mV @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a5eab4b42b02344063574ecea28b1dcb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS2150AFN/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for STPS2150AFN?","answer":"STMicroelectronics has not published a direct successor for the STPS2150AFN. A functionally similar Schottky diode in the same SMA Flat Leads package with 150 V / 2 A ratings would be the closest match. For higher current needs, look at the STPS3150 series (3 A) in the same package family, but verify the footprint and thermal limits for your board."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS2150AFN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS2150AFN when reusing this data.
