Its 45 ns reverse recovery time places it in the fast-recovery class (≤500 ns, >200 mA Io), making it suited for hard-switching topologies where reverse-recovery charge drives turn-on loss in the companion switch. ## 45 ns trr — switching loss and snubber design A 45 ns trr at 50 A forward current means the diode clears its stored charge quickly, limiting the current spike through the IGBT or MOSFET during the complementary device's turn-on. This reduces the snubber capacitance needed across the diode and keeps the switching node voltage overshoot within the 600 V blocking margin. ## TO-247-3 — thermal and mechanical fit The TO-247-3 through-hole package provides a large copper tab for heatsink attachment, sized for the 50 A continuous current. The 2.4 V forward voltage drop at 50 A produces 120 W conduction loss at full load, so the thermal interface to the heatsink — thermal pad compound, mounting torque, and airflow — determines the junction temperature. The 175 °C Tj(max) gives headroom, but the heatsink must keep the case temperature below about 150 °C to stay within the SOA.","metaTitle":"STTH50W06SW Fast Recovery Diode, 50A 600V TO-247, Obsolete","metaDescription":"STMicroelectronics STTH50W06SW standard fast recovery diode, 50 A average rectified, 600 V reverse, 45 ns trr, TO-247-3 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","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-247-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH50","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-247","Reverse Recovery Time (trr)":"45 ns","Current - Reverse Leakage @ Vr":"50 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"50A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"2.4 V @ 50 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH50W06SW/alternatives.json"},"ai":{"faq":[{"question":"Is STTH50W06SW obsolete?","answer":"Yes, the STTH50W06SW carries an Obsolete product status."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH50W06SW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH50W06SW when reusing this data.
