The full-pack (isolated tab) variant means the metal tab is electrically isolated — no heatsink insulation pad needed, and the tab can be bolted directly to a grounded chassis or shared heatsink without worrying about the 100 V rail. The 20 A average forward current and 900 mV forward drop at 20 A are typical for a 100 V Schottky in this package class. The fast recovery characteristic (≤500 ns above 200 mA) suits it for the output rectification stage of a 100–200 W switch-mode power supply or a DC-DC converter where Schottky's low reverse-recovery charge cuts switching loss. ST lists the STPS20SM100SFP as obsolete. The STPS20SM100S (same die in a standard TO-220 with non-isolated tab) is a common cross-shop candidate — the electrical specs match, but the package differs: the SFP full-pack is isolated, the S is not. A board designed for the full-pack's isolated tab needs a mechanical review before swapping to the S variant. ## Leakage and thermal limits Reverse leakage is 30 µA at 100 V. Junction temperature limit is 150 °C.","metaTitle":"STPS20SM100SFP Schottky Diode, 100 V 20 A TO-220FPAB","metaDescription":"STPS20SM100SFP is an ST 100 V 20 A Schottky rectifier in TO-220FPAB full-pack, fast recovery ≤500 ns.","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-220-3 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS20","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220FPAB","Current - Reverse Leakage @ Vr":"30 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"20A","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"900 mV @ 20 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e804b3806677e865f5a168058ab87abb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20SM100SFP/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20SM100SFP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20SM100SFP when reusing this data.
