That speed comes with a forward drop of 2.2 V at 12 A, so conduction loss is higher than a slower standard-recovery diode. STMicroelectronics lists the STTH1212G as Obsolete. No factory orders or last-time-buy windows remain. The only supply channel is independent distribution — surplus inventory, new-old-stock, or broker-sourced lots.","metaTitle":"STTH1212G Fast Recovery Diode, 1200 V, 12 A, 100 ns trr","metaDescription":"STTH1212G is a 1200 V, 12 A fast recovery rectifier with 100 ns trr in D2PAK.","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":"Tube","Technology":"Standard","Mounting Type":"Surface Mount","Package / Case":"TO-263-3, D²Pak (2 Leads + Tab), TO-263AB","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH1212","Capacitance @ Vr, F":"-","Supplier Device Package":"D2PAK","Reverse Recovery Time (trr)":"100 ns","Current - Reverse Leakage @ Vr":"10 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"12A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"2.2 V @ 12 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f69aa717155d402af7474b4d88c68164.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1212G/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STTH1212G?","answer":"ST does not list an official successor for the STTH1212G. A form-fit-function replacement would need to match the 1200 V reverse voltage, 12 A average current, 100 ns trr, and D2PAK footprint. A parametric search across ST's current fast-recovery diode portfolio or other vendors is the recommended approach."},{"question":"What are the specifications of STTH1212G?","answer":"The STTH1212G is a 1200 V, 12 A fast recovery rectifier with a 100 ns reverse recovery time.
