Its 40 ns reverse recovery time (trr) is the key parameter — it cuts the switching losses in continuous-conduction-mode PFC and lets the designer push the switching frequency higher without cooking the diode. STMicroelectronics lists the STTH8BC060D as Obsolete. ## Ratings that set the application envelope 600 V reverse voltage and 8 A average rectified current place this diode squarely in the 300–400 W PFC stage or output rectification of a 150–250 W flyback converter. The 3.6 V forward drop at 8 A is on the higher side for a fast diode — expect conduction loss to be a factor in the thermal budget, especially in a TO-220AC package without a heatsink.","metaTitle":"STTH8BC060D Fast Recovery Diode, 600 V 8 A, 40 ns trr","metaDescription":"STTH8BC060D fast recovery diode, 600 V, 8 A, 40 ns trr, TO-220AC.","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-220-2","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH8BC","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC","Reverse Recovery Time (trr)":"40 ns","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"8A","Operating Temperature - Junction":"-","Voltage - Forward (Vf) (Max) @ If":"3.6 V @ 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/57f47ed4a2d04f2e8d9eb7e83a4e3cce.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH8BC060D/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STTH8BC060D?","answer":"STMicroelectronics has not published an official replacement or cross-reference for the STTH8BC060D.
