This rating suggests the part is optimized for moderate-frequency rectification in continuous-conduction-mode power supplies where reverse-recovery losses matter. The TO-220-3 through-hole package is a standard power footprint — three leads with a metal tab for heatsink attachment. The common-cathode configuration means the center lead (tab) is the cathode common, simplifying PCB layout for a center-tapped secondary or dual-diode rectifier.","metaTitle":"STPS20M80CT Schottky Diode, 80V 10A, TO-220-3, Obsolete","metaDescription":"STPS20M80CT Schottky rectifier, 80V 10A per diode, fast recovery ≤500ns, TO-220-3.","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","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS20","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"30 µA @ 80 V","Voltage - DC Reverse (Vr) (Max)":"80 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"740 mV @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4c9d2d6890da660cce2b0e212b66b4cb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20M80CT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20M80CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20M80CT when reusing this data.
