The through-hole TO-220-3 package simplifies heatsink attachment for the continuous 16 A load. ## 40 ns trr — the switching-speed edge The 40 ns reverse recovery time separates this part from a standard-recovery 650 V rectifier. The 3.2 V forward drop at 8 A is the trade-off for fast recovery. ST lists the STTH16BC065CT as obsolete. For a production BOM that already carries this part, the options are: source remaining factory inventory or qualified surplus through the independent channel, or qualify a cross from another manufacturer. The common-cathode TO-220-3 footprint is widely used, so several 650 V, 16 A fast-recovery dual diodes exist — but each candidate must be evaluated for trr, Vf, and thermal performance against the original design's margin. ## Through-hole TO-220-3 — mounting and thermal design The TO-220-3 package (Supplier Device Package TO-220) mates the common-cathode pair's shared cathode to the metal tab, which is the primary thermal path. In a typical PFC boost layout, the tab is soldered to a copper island on the PCB or bolted to a heatsink with an insulating pad. The 16 A per diode rating assumes adequate heatsinking — without it, junction temperature will exceed the rated maximum at full load. The through-hole leads handle the mechanical stress of a bolted heatsink better than a surface-mount D²PAK would in high-vibration environments.","metaTitle":"STTH16BC065CT Fast Recovery Diode, 650 V, 16 A, TO-220-3","metaDescription":"STTH16BC065CT 650 V 16 A fast recovery diode in TO-220-3. 40 ns trr, common-cathode pair.","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-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH16","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Reverse Recovery Time (trr)":"40 ns","Voltage - DC Reverse (Vr) (Max)":"650 V","Operating Temperature - Junction":"-","Voltage - Forward (Vf) (Max) @ If":"3.2 V @ 8 A","Current - Average Rectified (Io) (per Diode)":"16A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/222597f44202f298feb07398b483b744.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH16BC065CT/alternatives.json"},"ai":{"faq":[{"question":"Is STTH16BC065CT obsolete?","answer":"Yes, ST lists the STTH16BC065CT as obsolete.
