Its 65 ns reverse recovery time (trr) makes it a strong candidate for the output stage of high-frequency DC-DC converters, boost PFC stages, and freewheeling diodes in motor-drive inverters where switching losses dominate the thermal budget. The DO-247 through-hole package handles the junction dissipation for sustained 60 A operation when properly heatsunk, and the AEC-Q101 qualification opens the door for under-hood and chassis-mounted applications across 12 V and 48 V automotive platforms. A 65 ns trr at rated current and voltage means the diode clears its stored charge quickly enough to keep reverse-recovery losses manageable at switching frequencies in the 50–150 kHz range. In a continuous-conduction-mode boost converter, that trr directly reduces the turn-on loss in the companion MOSFET and shrinks the snubber network needed to damp ringing. Compare this to a standard 200+ ns recovery diode in the same 600 V class — the STTH60RQ06WY can cut switching loss by 30–40 % at 100 kHz, which often lets you downsize the heatsink or push more output current through the same package. ## Automotive grade and junction temperature range AEC-Q101 qualification is the baseline for any semiconductor that sees the engine bay, transmission, or chassis electronics. The 80 µA reverse leakage at 600 V is a typical figure at 25 °C; expect it to rise with temperature, but the 175 °C rating gives you the headroom to derate without hitting thermal runaway. It is an active catalog line from ST, so franchised distribution carries it in volume. For BOM planning, this diode can be dual-sourced against the STTH60R06WY (same die, different package variant) if the board layout permits, but the DO-247 footprint is fixed.","metaTitle":"STTH60RQ06WY Automotive Fast Recovery Diode, 600V 60A DO-247","metaDescription":"STTH60RQ06WY automotive fast recovery diode, 600V 60A, 65 ns trr, AEC-Q101 qualified, DO-247 through-hole package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Grade":"Automotive","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Standard","Mounting Type":"Through Hole","Qualification":"AEC-Q101","Package / Case":"DO-247-2 (Straight Leads)","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH60","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-247","Reverse Recovery Time (trr)":"65 ns","Current - Reverse Leakage @ Vr":"80 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"60A","Operating Temperature - Junction":"-40°C ~ 175°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/774763fdd7246eace6e1faf83de5f536.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH60RQ06WY?","answer":"The reverse recovery time (trr) is 65 ns, measured under standard test conditions.
