Each diode is rated for 60 A average rectified current at a 400 V reverse voltage, with a 90 ns reverse recovery time. The 90 ns trr places this in the fast-recovery class (≤500 ns, >200 mA Io), suitable for high-frequency rectification and snubber circuits where switching losses matter. The forward drop is 1.2 V maximum at 60 A per diode. ## ISOTOP package and thermal design The ISOTOP (ISOTOP®) package is a chassis-mount module designed for bolting directly to a heatsink or cold plate. Maximum junction temperature is 150°C. Reverse leakage at 400 V is 50 µA, typical at 25°C — this rises with junction temperature and should be factored into the thermal budget at high load.","metaTitle":"STTH120L04TV1 Fast Recovery Diode, 400V 60A ISOTOP, Obsolete","metaDescription":"STTH120L04TV1 dual independent fast recovery diode, 400V Vr, 60A Io per diode, 90ns trr, ISOTOP chassis mount.","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)":"90 ns","Current - Reverse Leakage @ Vr":"50 µA @ 400 V","Voltage - DC Reverse (Vr) (Max)":"400 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.2 V @ 60 A","Current - Average Rectified (Io) (per Diode)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$27.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/330c4c923d153c7c2f4d4375f39555a5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH120L04TV1/alternatives.json"},"ai":{"faq":[{"question":"Is the STTH120L04TV1 obsolete?","answer":"Yes, the STTH120L04TV1 carries an Obsolete product status from STMicroelectronics.
