The D2PAK surface-mount package with exposed tab handles the thermal load — the tab is the cathode common, so the board copper plane does double duty as heat sink and current path. Forward voltage is 790 mV maximum at 15 A; reverse leakage is 40 µA at 80 V. The junction temperature ceiling is 175°C, which gives headroom in a hot PSU or OR-ing diode application. ## Pin-compatible alternatives — what to look for For a pin-compatible replacement, look for a dual common-cathode Schottky in D2PAK rated at least 80 V and 15 A per diode, with a forward voltage at or below 790 mV at 15 A. The tab is the common cathode — any substitute must match that pinout to avoid a board spin.","metaTitle":"STPS30SM80CG-TR Schottky Diode, 80V 15A Dual Common Cathode","metaDescription":"STPS30SM80CG-TR Schottky diode, 80V 15A per diode, 790mV Vf at 15A, dual common cathode 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":"STPS30","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"D²PAK","Current - Reverse Leakage @ Vr":"40 µA @ 80 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"790 mV @ 15 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c30595e7af9f4cfddb5f78be68c2468a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS30SM80CG-TR/alternatives.json"},"ai":{"faq":[{"question":"Is STPS30SM80CG-TR obsolete?","answer":"Yes, STMicroelectronics lists the STPS30SM80CG-TR as obsolete."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS30SM80CG-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS30SM80CG-TR when reusing this data.
