The common-cathode pair is typically used in center-tapped secondary rectification for switch-mode power supplies, OR-ing diodes in redundant power architectures, or as a freewheeling clamp in motor-drive and inverter stages where the Schottky's fast recovery (≤500 ns, >200 mA) and low Vf keep switching losses down. ST officially lists the STPS20L60CTN as obsolete. There is no successor order code in the record, so a direct drop-in from ST is not published. For a production BOM that was qualified on this exact part number, the path is either sourcing remaining factory-origin inventory through independent distribution (date-code and lot traceability verified at quote) or qualifying a functional substitute with the same common-cathode TO-220AB footprint. The reverse leakage at 60 V is 350 µA, and the junction temperature maxes at 150°C — these are the parameters a replacement must meet or exceed. ## Package and mounting — the narrow-lead detail The STPS20L60CTN uses the TO-220AB narrow-leads variant (supplier device package), not the standard-width TO-220AB. The lead spacing is tighter, which means the hole pattern on the PCB or the heatsink clip must match the narrow dimension. It is a through-hole device in a TO-220-3 case, shipped in tube form. If a replacement part uses standard-width leads, the mechanical fit will not work without bending or re-drilling.","metaTitle":"STPS20L60CTN Schottky Rectifier, 60V 20A Common Cathode","metaDescription":"STPS20L60CTN dual Schottky rectifier, 60V Vr, 10A per diode, 600mV Vf at 10A, TO-220AB narrow leads.","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-220AB Narrow Leads","Current - Reverse Leakage @ Vr":"350 µA @ 60 V","Voltage - DC Reverse (Vr) (Max)":"60 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"600 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/29e7d5793e956603bc854f578527913d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20L60CTN/alternatives.json"},"ai":{"faq":[{"question":"Is STPS20L60CTN obsolete?","answer":"Yes, STMicroelectronics lists the STPS20L60CTN as obsolete.
