Its 45 ns reverse recovery time (trr) places it squarely in the fast-recovery class, designed to handle the high-frequency switching in power supplies, PFC stages, and flyback converters where recovery losses directly affect efficiency and thermal budget. The 1.7 V forward voltage at 1 A is typical for a 600 V fast diode — expect conduction loss to be a factor in the heatsink calculation, not a surprise. ## Package and reflow reality It comes in a DO-214AC (SMA) surface-mount package. That is a standard footprint for automated pick-and-place, but the SMA body is small — check your solder-paste stencil aperture for adequate fillet height. No MSL rating is listed in the record, so treat it as MSL 1 by default (no bake required) unless the reel label says otherwise.","metaTitle":"STTH1R06A Fast Recovery Rectifier, 600V 1A, 45ns trr, SMA","metaDescription":"STMicroelectronics STTH1R06A fast recovery rectifier diode: 600V reverse voltage, 1A average current, 45ns trr, DO-214AC SMA 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":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Standard","Mounting Type":"Surface Mount","Package / Case":"DO-214AC, SMA","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1","Capacitance @ Vr, F":"-","Supplier Device Package":"SMA","Reverse Recovery Time (trr)":"45 ns","Current - Reverse Leakage @ Vr":"1 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.7 V @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06bbb223123f0c38be48d8898e0d18b7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of the STTH1R06A?","answer":"The reverse recovery time (trr) is 45 ns, which qualifies it as a fast-recovery diode suitable for switching frequencies in the tens to low hundreds of kilohertz."},{"question":"What are the specifications of the STTH1R06A?","answer":"The STTH1R06A is a 600 V, 1 A standard fast-recovery rectifier with a 45 ns reverse recovery time, 1.7 V forward voltage at 1 A, 1 µA reverse leakage at 600 V, and a 175°C maximum junction temperature.
