The 2.2 V forward drop at 20 A is a typical fast-recovery trade-off — you get the speed but pay a higher Vf than an ultrafast or Schottky alternative. ## Obsolete — the sourcing reality for this line item STMicroelectronics lists the STTH80S06W as Obsolete. ## 175°C junction — thermal margin for high-ambient environments This matters for a 80 A part: at full rated current, the junction will run hot even with a good heatsink, and the 175°C ceiling gives headroom for derating in a 60°C to 85°C ambient inside a motor drive or solar inverter enclosure. The 50 µA reverse leakage at 600 V is a typical value at 25°C; expect it to rise with temperature, so the leakage power contribution should be factored into the thermal model at high junction temperatures.","metaTitle":"ST STTH80S06W Fast Recovery Diode, 80A 600V DO-247","metaDescription":"STTH80S06W 80A 600V fast recovery diode, 75ns 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":"STTH80","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-247","Reverse Recovery Time (trr)":"75 ns","Current - Reverse Leakage @ Vr":"50 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"80A","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"2.2 V @ 20 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH80S06W/alternatives.json"},"ai":{"faq":[{"question":"Can I use STTH80S06W in a 600V circuit?","answer":"Yes. The STTH80S06W is rated for 600 V DC reverse voltage (Vr max), making it suitable for 400 V bus rails, PFC stages, and other 600 V class power circuits.
