That trr figure is the key switching parameter: it determines the recovery losses in continuous-conduction-mode PFC boost stages, hard-switching flyback converters, and output rectification in 100–300 W SMPS designs. A 55 ns trr keeps the reverse-recovery charge low enough that the MOSFET or IGBT in the same leg does not see excessive turn-on stress at switching frequencies up to the 100 kHz range. ## 600 V / 8 A — continuous rating for PFC and DC-DC stages Rated 600 V reverse voltage and 8 A average rectified current (Io). The 600 V blocking voltage covers universal-input PFC boost stages (nominal 380–400 VDC bus) with margin for line transients. The 8 A continuous rating suits boost, flyback, and two-switch forward converters in the 150–400 W output range. Forward voltage is 1.85 V max at 8 A — a typical conduction loss for an 8 A fast-recovery die in a D2PAK. Reverse leakage is 8 µA at 600 V, 25°C, which rises with junction temperature but stays within the thermal budget for most designs. ## D2PAK (TO-263) — surface-mount power tab Supplied in a D2PAK (TO-263-3, 2 leads plus tab) surface-mount package. For 8 A continuous, a minimum of 6–8 cm² of 2 oz copper on the tab side is typical to keep Tj below 125°C in still air.","metaTitle":"STTH806G 600V 8A Fast Recovery Diode, 55ns trr, D2PAK","metaDescription":"STTH806G 600V 8A fast recovery diode, 55ns trr, D2PAK surface mount.","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":"Surface Mount","Package / Case":"TO-263-3, D2PAK (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH806","Capacitance @ Vr, F":"-","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"55 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":"1.85 V @ 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c41786373b838cc32a7a70220de4c835.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH806G","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH806G when reusing this data.
