Its 40 ns reverse recovery time qualifies it for high-frequency switching in PFC boost stages, output rectification, and snubber circuits where recovery losses drive thermal design. ## 40 ns trr — switching loss in the high-voltage rail The 40 ns reverse recovery time is the headline switching spec. Forward voltage is 3.1 V at 15 A. STMicroelectronics lists the STTH15S12W as obsolete.","metaTitle":"STTH15S12W Fast Recovery Diode, 1200 V, 15 A, DO-247","metaDescription":"STTH15S12W fast recovery diode, 1200 V, 15 A, 40 ns trr, DO-247 through-hole.","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":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-247-2 (Straight Leads)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH15S","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-247","Reverse Recovery Time (trr)":"40 ns","Current - Reverse Leakage @ Vr":"10 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"15A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"3.1 V @ 15 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c979f22e6c42b8264d9a0fa75bd66a18.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH15S12W/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH15S12W","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH15S12W when reusing this data.
