Each diode delivers an average rectified current of 60 A with a forward voltage drop of 2.25 V at that current. The 125 ns reverse recovery time classifies it as a fast recovery device (under 500 ns), suited for high-frequency rectification in power converters, motor drives, and welding equipment where switching losses matter. The ISOTOP package is chassis-mountable, designed for bolting to a heatsink, and the dual-diode configuration lets you build a center-tapped rectifier or a pair of freewheeling diodes from one module. ## 125 ns trr — the switching-speed decision The 125 ns reverse recovery time is the headline switching spec. In a hard-switched bridge leg at 20–50 kHz, that trr keeps the recovery charge low enough to avoid excessive turn-on losses in the complementary switch. Compare to a standard recovery diode (trr in the microsecond range) where the same circuit would need snubbers or a lower switching frequency. The fast recovery characteristic also reduces EMI from reverse recovery current spikes, which simplifies filter design. The STTH12012TV2 is marked obsolete by STMicroelectronics.","metaTitle":"STTH12012TV2 Fast Recovery Diode, 1200V 60A ISOTOP, Obsolete","metaDescription":"STTH12012TV2 dual fast recovery diode, 1200V 60A per diode, 125ns trr, ISOTOP 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","Technology":"Standard","Mounting Type":"Chassis Mount","Package / Case":"ISOTOP","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH120","Diode Configuration":"2 Independent","Supplier Device Package":"ISOTOP®","Reverse Recovery Time (trr)":"125 ns","Current - Reverse Leakage @ Vr":"30 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Voltage - Forward (Vf) (Max) @ If":"2.25 V @ 60 A","Current - Average Rectified (Io) (per Diode)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$26.5300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e25a0475cad5daf16b0cbdad41fd08c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH12012TV2/alternatives.json"},"ai":{"faq":[{"question":"Is STTH12012TV2 obsolete and where can I find it?","answer":"Yes, STMicroelectronics lists the STTH12012TV2 as obsolete.
