The ISOTOP package is designed for this — the copper baseplate and M6 screw terminals let you bolt it to a heatsink with a low thermal resistance path. The 400 V blocking rating covers 230 VAC rectified rails with margin, and the 60 µA reverse leakage at 400 V (25 °C) stays manageable through the 150 °C junction temperature limit. ## Two independent diodes in one package The two independent diodes share the ISOTOP baseplate but are electrically isolated from each other. This lets you wire them as a center-tap full-wave rectifier, a dual output rectifier for split-rail supplies, or parallel them for a 120 A capability with matched Vf sharing. The common cathode or common anode configuration is not fixed — you choose the circuit topology. STMicroelectronics lists the STTH120R04TV1 as Active.","metaTitle":"STTH120R04TV1 Fast Recovery Diode, 60A 400V ISOTOP","metaDescription":"STTH120R04TV1 dual fast recovery diode, 80 ns trr, 60A per diode, 400V reverse voltage, ISOTOP chassis mount.","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":"-","Package":"Tube","Technology":"Standard","Mounting Type":"Chassis Mount","Package / Case":"ISOTOP","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STTH120","Diode Configuration":"2 Independent","Supplier Device Package":"ISOTOP®","Reverse Recovery Time (trr)":"80 ns","Current - Reverse Leakage @ Vr":"60 µA @ 400 V","Voltage - DC Reverse (Vr) (Max)":"400 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.5 V @ 60 A","Current - Average Rectified (Io) (per Diode)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$26.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/429dbec5bf30c1e576fdb16f0a405ec1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH120R04TV1/alternatives.json"},"ai":{"faq":[{"question":"What is the reverse recovery time of the STTH120R04TV1?","answer":"The reverse recovery time (trr) is 80 ns, measured under standard test conditions for fast-recovery diodes.
