It carries a fast-recovery characteristic (≤ 500 ns, > 200 mA) typical of Schottky technology, with a forward voltage drop of 820 mV at the rated 1 A forward current. For a BOM that requires this exact diode, procurement must turn to independent distribution — surplus, new-old-stock reels. ## 820 mV Vf at 1 A — thermal budget check At 1 A forward current the STPS1150M exhibits 820 mV typical forward drop. That translates to roughly 820 mW of dissipation — manageable in the STmite package if the board has adequate copper spreading, but tight for a compact design without airflow. The 175°C junction rating provides headroom, but the thermal resistance of the DO-216AA means the trace-connected cathode tab is the primary heat path.","metaTitle":"STPS1150M Schottky Diode, 150 V, 1 A, STmite, Obsolete","metaDescription":"STPS1150M Schottky rectifier: 150 V reverse voltage, 1 A average current, 820 mV Vf at 1 A, 175°C Tj max, DO-216AA STmite.","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)","Technology":"Schottky","Mounting Type":"Surface Mount","Package / Case":"DO-216AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS1150","Capacitance @ Vr, F":"-","Supplier Device Package":"STmite","Current - Reverse Leakage @ Vr":"1 µA @ 150 V","Voltage - DC Reverse (Vr) (Max)":"150 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"820 mV @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6cc6d4f9c06dbfceea56944f1ab2d6bd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS1150M/alternatives.json"},"ai":{"faq":[{"question":"Can I use the STPS1150M in a high-temperature application?","answer":"Yes, the maximum junction temperature is 175°C, which qualifies it for under-hood automotive or industrial environments where ambient temperatures exceed 125°C.
