ST lists the STPS15SM80CG-TR as Obsolete. That means no further factory orders are accepted, and the part is not being manufactured. For a BOM line that still calls out this order code, the only channel is surplus inventory — sealed reels or cut tape from factory overruns, distribution closeouts, or broker stock. The date-code spread and packaging condition matter here: a reel with a single production date-code is preferable to a mixed-lot tube. We source these against an RFQ, confirming availability and pricing at quote time — no stock promise on the page, but the desk can check what is physically on hand. The 80 V Vr rating gives headroom on a 48 V rail (derating to 60% is comfortable) but is tight for a 60 V rail if you follow the common 80% derating guideline — that leaves 64 V, so a 60 V rail is at the limit. The 7.5 A per diode is the DC average; in a forward converter or OR-ing application the actual RMS current may be higher, so check the I²R heating against the package's thermal impedance. The 20 µA leakage at 80 V and 175°C maximum junction temperature are typical for a Schottky of this voltage class — leakage doubles with temperature, so at high ambient the self-heating must be budgeted. The 780 mV Vf at 7.5 A is the forward drop at rated current; at lighter loads it drops, improving efficiency in standby.","metaTitle":"STPS15SM80CG-TR Schottky Diode, 80 V, 7.5 A, D²Pak, Obsolete","metaDescription":"STPS15SM80CG-TR is an 80 V, 7.5 A dual Schottky diode in D²Pak.","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":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS15","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D²PAK","Current - Reverse Leakage @ Vr":"20 µA @ 80 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"780 mV @ 7.5 A","Current - Average Rectified (Io) (per Diode)":"7.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6fc963500e2a29e78e47d3de7db50bd6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS15SM80CG-TR/alternatives.json"},"ai":{"faq":[{"question":"What are the specifications of STPS15SM80CG-TR?","answer":"It is a dual common-cathode Schottky diode rated for 80 V reverse voltage, 7.5 A average rectified current per diode, with a forward voltage drop of 780 mV max at 7.5 A.
