At 30 A forward current the forward voltage drop is 2 V max, so conduction loss at full load is 60 W; the DO-247 package with its large copper tab must be heatsunk to keep junction temperature below the 175°C absolute maximum. ## AEC-Q101 qualification and automotive deployment ## Package and mounting — DO-247 through-hole The DO-247-2 package with straight leads is a through-hole package designed for high-current rectification. The large copper tab provides a low thermal resistance path to the heatsink — the mounting hole pattern matches standard TO-247 heatsink clips. The through-hole leads handle the 30 A continuous current without the trace-width constraints of a surface-mount package.","metaTitle":"STTH3010WY 30A 1000V Fast Recovery Diode, AEC-Q101, DO-247","metaDescription":"STTH3010WY automotive fast recovery diode: 30 A average, 1000 V reverse, 100 ns trr, AEC-Q101 qualified, -40°C to 175°C junction.","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":"STTH3010","Capacitance @ Vr, F":"-","Reverse Recovery Time (trr)":"100 ns","Current - Reverse Leakage @ Vr":"15 µA @ 1000 V","Voltage - DC Reverse (Vr) (Max)":"1000 V","Current - Average Rectified (Io)":"30A","Operating Temperature - Junction":"-40°C ~ 175°C","Voltage - Forward (Vf) (Max) @ If":"2 V @ 30 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c75faa61eb02f25b514dfabfd4a0bda7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does STTH3010WY meet AEC-Q101 qualification?","answer":"Yes, the STTH3010WY is AEC-Q101 qualified, which is the automotive-grade discrete semiconductor qualification standard.

Both share the same 1000 V reverse voltage, 30 A average current, and 100 ns trr ratings, but the STTH3010WY adds AEC-Q101 qualification and a -40°C to 175°C junction temperature range versus the commercial-grade STTH3010's narrower range.
