The through-hole form factor suits wave-solder assembly and provides robust mechanical retention in high-vibration environments such as industrial power supplies and automotive auxiliary converters.","metaTitle":"STPS20SM120SR Schottky Rectifier, 120 V, 20 A, I2PAK","metaDescription":"STPS20SM120SR is an obsolete STMicroelectronics 120 V, 20 A Schottky rectifier in a through-hole I2PAK package.","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":"ECOPACK®2","Package":"Tube","Technology":"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":"STPS20","Capacitance @ Vr, F":"-","Supplier Device Package":"I2PAK","Current - Reverse Leakage @ Vr":"210 µA @ 120 V","Voltage - DC Reverse (Vr) (Max)":"120 V","Current - Average Rectified (Io)":"20A","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"890 mV @ 20 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/00ac4d13df6e6bd8236a78bd4b9965a5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20SM120SR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20SM120SR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20SM120SR when reusing this data.
