At 12 A forward current and 1000 V blocking voltage, this trr keeps the turn-off losses low enough for continuous-conduction-mode PFC boost stages operating in the 50–100 kHz range. STMicroelectronics lists the STTH1210FP as obsolete. The base product number is STTH1210, and the TO-220FPAC variant is the full-pack version. ## Reverse leakage and temperature margin Reverse leakage current is specified at 10 µA max at 1000 V reverse voltage. At high junction temperatures — the device is rated to 175 °C — leakage rises exponentially, so the thermal design should keep the junction well below that ceiling under steady-state load to avoid runaway. The 12 A average rectified current is the DC output rating; the actual ripple current capability depends on the heatsink and ambient temperature.","metaTitle":"STTH1210FP Fast Recovery Diode, 1000 V 12 A, 90 ns trr","metaDescription":"STTH1210FP is an obsolete STMicroelectronics fast recovery diode, 1000 V 12 A, 90 ns trr, TO-220FPAC through-hole package.","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","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-220-2 Full Pack","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH1210","Capacitance @ Vr, F":"-","Supplier Device Package":"TO-220FPAC","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":"175°C(Max)","Voltage - Forward (Vf) (Max) @ If":"2 V @ 12 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9900e8509a795f5661bcb64a48ade96f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH1210FP/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH1210FP?","answer":"The reverse recovery time (trr) is 90 ns.
