STMicroelectronics lists the STPS20L120CFP as Obsolete. ## Key ratings for the bench and the board The 120 V reverse voltage gives comfortable derating margin on a 48 V or 60 V bus — you are not riding the absolute maximum. The 860 mV forward drop at 10 A is typical for a 120 V Schottky at this current density; expect about 8.6 W conduction loss per diode at full load, so the full-pack case needs a decent heatsink or forced air. Reverse leakage is 120 µA at 120 V — negligible at room temperature but it doubles roughly every 10 °C junction rise, so budget for it above 100 °C. The junction temperature limit is 150 °C max, which is standard for power Schottkys.","metaTitle":"STPS20L120CFP Schottky Diode, 120V 20A Common Cathode","metaDescription":"STPS20L120CFP dual Schottky rectifier: 120 V, 10 A per diode, 860 mV Vf, TO-220FPAB.","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 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS20","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220FPAB","Current - Reverse Leakage @ Vr":"120 µA @ 120 V","Voltage - DC Reverse (Vr) (Max)":"120 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"860 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/b0518ad8d88487c2133b92ab71939652.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20L120CFP/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20L120CFP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20L120CFP when reusing this data.
