The switching speed falls under the fast-recovery class — ≤ 500 ns at currents above 200 mA — which suits it for output rectification in switch-mode power supplies and freewheeling diode roles in motor drives or DC-DC converters. For a production BOM that calls this exact diode, the path is last-time-buy inventory through independent distribution. ## Package and thermal context Housed in a TO-220-3 through-hole package with narrow leads. Maximum junction temperature is 175 °C.","metaTitle":"STPS20120CTN Schottky Diode, 120 V, 10 A, TO-220AB, Obsolete","metaDescription":"STPS20120CTN dual common-cathode Schottky rectifier, 120 V, 10 A per diode, 920 mV Vf, 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":"STPS20120","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220AB Narrow Leads","Current - Reverse Leakage @ Vr":"10 µA @ 120 V","Voltage - DC Reverse (Vr) (Max)":"120 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"920 mV @ 10 A","Current - Average Rectified (Io) (per Diode)":"10A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3ae7eecedc29099cf5430c0bf68e4f96.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS20120CTN/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20120CTN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20120CTN when reusing this data.
