Its 55 ns reverse recovery time (trr) puts it in the ultrafast class for a 600 V / 30 A die — fast enough to keep switching losses manageable in hard-switched boost PFC stages, DC-DC converters, and motor-drive freewheel paths running at 50–150 kHz. The DO-247 through-hole package handles the junction-to-case thermal path for 30 A average current; the 2.95 V forward drop at 30 A means the thermal design must budget roughly 88 W of conduction loss plus switching losses, so a heatsink or forced-air flow is assumed for continuous operation. ## Junction temperature and automotive screening Rated operating junction temperature spans -40°C to 175°C, which covers under-hood and transmission-oil environments where ambient can exceed 125°C. For a buyer sourcing this for an ECU or inverter BOM, the AEC-Q101 certificate and ST's own traceability system are the provenance chain to verify — the date-code laser etch on the DO-247 body should match ST's factory marking standard for the plant and week code. ## Active status, no LTB pressure ST lists the STTH30RQ06WY as an active product.","metaTitle":"STTH30RQ06WY Automotive Fast Recovery Diode, 600V 30A","metaDescription":"STMicroelectronics STTH30RQ06WY 600V 30A fast recovery rectifier, AEC-Q101 qualified, 55ns trr, DO-247 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":"Automotive, AEC-Q101","Package":"Tube","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-247-2 (Straight Leads)","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH30","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-247","Reverse Recovery Time (trr)":"55 ns","Current - Reverse Leakage @ Vr":"40 µA @ 600 V","Voltage - DC Reverse (Vr) (Max)":"600 V","Current - Average Rectified (Io)":"30A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"2.95 V @ 30 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f49b7c65efd7bc091b25f3beab22ccb7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STTH30RQ06WY equivalent to STTH30R06WY?","answer":"The STTH30R06WY is a closely related sibling in ST's 30 A, 600 V fast-recovery family. The 'Q' in the STTH30RQ06WY order code typically denotes the AEC-Q101 automotive qualification level. The base silicon and package are the same DO-247, but the non-automotive STTH30R06WY may not carry the same stress screening or temperature cycling requirements.

The DO-247 package and lead finish are lead-free compatible.
