The 30 ns reverse recovery time is the headline: it is fast enough to keep switching losses manageable at 100 kHz in a PFC stage, but not so aggressive that it rings or snap-commutates like an ultrafast silicon carbide part. That middle ground makes it a practical swap-in for older 200 V fast-recovery designs that used slower 100–200 ns parts — the 30 ns trr buys efficiency without forcing a gate-drive re-tune. ## 3 A continuous in a DO-201AD — thermal reality Rated for 3 A average rectified current in the DO-201AD axial package. That is a continuous rating, not a surge — the junction temperature maxes out at 175°C, so the lead length and any heatsinking on the anode/cathode bands determine whether you actually get 3 A out of it in your board. In a through-hole layout with 10 mm leads and no forced air, derate it. The forward voltage drop is 1 V at 3 A, which puts conduction loss at 3 W — that heat has to go somewhere. The 3 µA reverse leakage at 200 V is tight enough for offline supplies. ## Active, in the catalog, no LTB clock ticking Lifecycle status is Active — ST is still manufacturing this part, no last-time-buy notice, no end-of-life.","metaTitle":"ST STTH3R02 Fast Recovery Rectifier, 200 V 3 A DO-201AD","metaDescription":"STTH3R02 fast recovery rectifier: 200 V, 3 A, 30 ns trr in DO-201AD axial 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":"Cut Tape (CT); Tape & Box (TB)","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH3","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-201AD","Reverse Recovery Time (trr)":"30 ns","Current - Reverse Leakage @ Vr":"3 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1 V @ 3 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/888354eab58bba474e33e185f8d37ec2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH3R02?","answer":"The reverse recovery time (trr) is 30 ns, making it a fast recovery rectifier suitable for switching frequencies up to about 100 kHz in typical PFC or flyback circuits."},{"question":"What package does STTH3R02 come in?","answer":"It comes in a DO-201AD axial package, a through-hole form factor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH3R02","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH3R02 when reusing this data.
