The TO-220 Full Pack (TO-220FPAC) has an isolated tab, so no mica insulator or thermal pad is needed against a grounded heatsink — a time-saver in through-hole assembly. ## 1000 V / 8 A — the operating envelope Rated 1000 V DC reverse (Vr) and 8 A average rectified current (Io), the STTH810FP handles 240 VAC or 277 VAC rectified rails with margin. Forward voltage is 2 V max at 8 A, which at 85 ns recovery means the diode runs warm but stays inside a 175°C junction limit. The 5 µA reverse leakage at 1000 V is clean enough for a high-voltage bulk rail; no pre-load resistor needed to balance the bus. Product status is Active. That means no last-time-buy window to track, no forced redesign for a replacement part.","metaTitle":"STTH810FP Fast Recovery Diode, 1000 V 8 A, 85 ns trr","metaDescription":"STTH810FP fast recovery diode from STMicroelectronics: 1000 V, 8 A, 85 ns trr in TO-220FPAC isolated package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-2 Full Pack, Isolated Tab","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH810","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220FPAC","Reverse Recovery Time (trr)":"85 ns","Current - Reverse Leakage @ Vr":"5 µA @ 1000 V","Voltage - DC Reverse (Vr) (Max)":"1000 V","Current - Average Rectified (Io)":"8A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"2 V @ 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9a5cedabe81efb2084564b532ffe657c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH810FP?","answer":"85 ns (trr), which qualifies as Fast Recovery (≤ 500 ns, > 200 mA Io).
