The junction is rated to 175 °C max, which matters when the part is bolted into a cramped chassis with marginal airflow — the thermal margin is real. ST lists the STTH212 as Obsolete. If you're repairing a board that carries this diode, the path is either a pin-compatible fast-recovery diode from another manufacturer (same DO-201AD footprint, 1200 V, 2 A, trr ≤ 75 ns) or sourcing remaining stock through independent distribution. The 1.75 V forward drop at 2 A is a check point when selecting a substitute — a part with significantly higher Vf will run hotter in the same hole. ## Sourcing the STTH212 today Because the STTH212 is obsolete, standard distributor shelves are empty.","metaTitle":"STTH212 Fast Recovery Diode, 1200 V, 2 A, DO-201AD","metaDescription":"STTH212 fast recovery rectifier: 75 ns trr, 1200 V Vrrm, 2 A Io in DO-201AD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH21","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-201AD","Reverse Recovery Time (trr)":"75 ns","Current - Reverse Leakage @ Vr":"10 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.75 V @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9197f644d8a2de13cedf274f7aa484e8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH212/alternatives.json"},"ai":{"faq":[{"question":"Is STTH212 obsolete?","answer":"Yes.
