The ISOTOP baseplate is designed for chassis mounting, which means the thermal path runs through the mounting surface into the heatsink — the package itself is the power loop. A 115 ns reverse recovery time at 30 A forward current and 1200 V blocking voltage is fast enough for continuous-conduction-mode PFC stages in the 50–100 kHz range and for output rectification in phase-shifted full-bridge converters. The fast recovery reduces turn-off losses compared to a standard recovery diode, which matters when the junction temperature is already at the 150 °C maximum rating. Slower diodes in the same voltage class would run 200–500 ns and force a snubber or a derating of switching frequency. ## Obsolete — the sourcing picture No replacement part number is recorded in the official transition notice. ## ISOTOP mounting — what the chassis-mount package expects The ISOTOP (also called ISOTOP®) package is a power module with a nickel-plated copper baseplate and M4 or M5 mounting screws. The two independent diodes share the baseplate as the common cathode or are isolated depending on the internal wiring — this variant uses two independent diodes, so each anode and cathode pair is separate. The package is delivered in Tube, not Tape & Reel. Chassis mounting means the thermal interface material between the baseplate and heatsink determines the junction-to-case thermal resistance; a 0.1 mm layer of thermal grease is the standard practice for this package class.","metaTitle":"ST STTH6112TV1 Fast Recovery Diode, 1200V 30A ISOTOP","metaDescription":"STTH6112TV1 dual fast recovery diode, 1200V 30A per diode, 115ns 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":"STTH61","Diode Configuration":"2 Independent","Supplier Device Package":"ISOTOP®","Reverse Recovery Time (trr)":"115 ns","Current - Reverse Leakage @ Vr":"20 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"2.25 V @ 30 A","Current - Average Rectified (Io) (per Diode)":"30A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$26.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c1e7ac50a12f854d0ce6af18432b9744.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STTH6112TV1 obsolete?","answer":"Yes, STMicroelectronics lists the STTH6112TV1 as Obsolete."},{"question":"What is the closest alternative to STTH6112TV1?","answer":"No pin-compatible drop-in replacement is recorded in the official documentation. The STTH61 family uses the same die technology in other packages (e.g., TO-247, D²PAK), but the ISOTOP dual-diode form factor is specific to the TV1 suffix.
