It belongs to the STTH1210 family and carries the Automotive AEC-Q101 qualification, which means it is specified and tested for use in automotive power-train, body electronics, and other high-reliability environments where a standard rectifier would not pass the stress screens. The 90 ns reverse recovery time (trr) puts it in the fast-recovery class — useful for switching power supplies, PFC boost stages, and output rectification where recovery losses and EMI matter. The 1000 V reverse voltage (Vr) covers off-line rectification up to 240 VAC input with margin for line transients. The 12 A average forward current (Io) is the continuous rating — in a typical PFC boost stage that means roughly 1–1.5 kW output before thermal derating kicks in. Forward voltage drop is 2 V at 12 A, so at full load expect about 24 W of conduction loss; the TO-220AC package with a heatsink is expected. The 90 ns trr is the headline switching spec: it keeps reverse-recovery losses manageable at switching frequencies up to about 100 kHz, though for higher frequencies an ultrafast (<50 ns) part would be a better fit. ## Automotive qualification and lifecycle","metaTitle":"STTH1210DY Fast Recovery Diode, 12A 1000V, AEC-Q101","metaDescription":"STTH1210DY automotive AEC-Q101 fast recovery rectifier: 12A average, 1000V reverse, 90 ns trr, TO-220AC.","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":"TO-220-2","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH1210","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220AC","Reverse Recovery Time (trr)":"90 ns","Current - Reverse Leakage @ Vr":"10 µA @ 1000 V","Voltage - DC Reverse (Vr) (Max)":"1000 V","Current - Average Rectified (Io)":"12A","Operating Temperature - Junction":"-40°C~175°C","Voltage - Forward (Vf) (Max) @ If":"2 V @ 12 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69b74d1eddb0c6d50878e5172df0421f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1210DY/alternatives.json"},"ai":{"faq":[{"question":"Can STTH1210DY be used in automotive applications?","answer":"Yes.
