Its reverse recovery time of 105 ns places it squarely in the fast-recovery class — fast enough for continuous-conduction-mode PFC boost stages, output rectification in flyback converters, and snubber clamping in motor drives, without the higher Vf penalty of an ultrafast device. ## 1.3 Vf at 8 A — thermal budget in the D2PAK Forward voltage is 1.3 V at the full 8 A rated current, which puts conduction losses at about 10.4 W. The D2PAK's exposed tab on the bottom carries most of the heat — without a proper via-stitched thermal land on the PCB, junction temperature will climb past the 175 °C maximum under sustained full load. The 8 µA reverse leakage at 600 V is low for a 600 V-class device, which helps in standby-light-load efficiency. STMicroelectronics no longer manufactures this part as a standard catalogue item, and no direct-replacement order code is listed on the official record. No pin-compatible drop-in has been validated as an official second source; any substitution requires a design review of the switching characteristics.","metaTitle":"STTH8L06G Fast Recovery Diode, 8A 600V 105ns, D2PAK","metaDescription":"STMicroelectronics STTH8L06G standard fast recovery diode: 8A average, 600V reverse, 105ns trr, D2PAK.","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":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH8L06","Capacitance @ Vr, F":"-","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"105 ns","Current - Reverse Leakage @ Vr":"8 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"8A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.3 V @ 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06bbb223123f0c38be48d8898e0d18b7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for STTH8L06G?","answer":"No official replacement order code is listed by STMicroelectronics for the STTH8L06G.
