The reverse leakage at 80 V is 40 µA, which climbs with temperature but stays manageable for most power-converter designs. ## Recovery speed and switching behaviour Listed as a fast-recovery Schottky with recovery time ≤ 500 ns at > 200 mA — typical for a 15 A Schottky in this voltage class. That's fast enough for 50–100 kHz switching supplies; above that, the reverse-recovery charge starts eating into efficiency, and a SiC or GaN diode would be a better fit. STMicroelectronics has ended production, so new stock is not available through the factory or authorised distributors. Sourcing is limited to independent distribution — surplus inventory, new-old-stock, or broker-sourced lots. No official successor has been published by ST.","metaTitle":"STPS30SM80CR Schottky Diode, 80V 15A Common Cathode, I2PAK","metaDescription":"STPS30SM80CR Schottky rectifier, 80V 15A per diode, 790mV Vf, 175°C Tj.","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":"Tube","Diode Type":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-262-3 Long Leads, I²Pak, TO-262AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS30","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"I2PAK","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/STPS30SM80CR/alternatives.json"},"ai":{"faq":[{"question":"Is the STPS30SM80CR obsolete?","answer":"Yes, the STPS30SM80CR is listed as obsolete by STMicroelectronics.
