Its 80 ns reverse recovery time (trr) at 400 V reverse voltage puts it squarely in the high-frequency PFC boost, output rectification, and freewheeling diode role where a standard recovery part would burn through the switching budget. The 1.45 V forward drop at 100 A is the conduction loss number the thermal designer needs for the heatsink calculation. Junction temperature range covers -55°C to 150°C, which covers industrial and most automotive under-hood environments. ## 80 ns trr — why it matters for the switching frequency decision The 80 ns reverse recovery time is the headline switching parameter. At 400 V bus voltage and 100 A switched current, each recovery event dissipates energy proportional to trr times the voltage. An 80 ns trr keeps the recovery loss manageable at 20–50 kHz switching frequencies typical of IGBT-based PFC stages. If the design pushes toward 100 kHz with SiC FETs, the recovery charge of a fast epitaxial diode like this still works, but the margin narrows — the buyer should confirm the total switching loss against the thermal budget at their actual frequency. ## ISOTOP package — mounting and thermal interface The ISOTOP (also known as SOT-227B) package is a four-screw chassis-mount module with an exposed metal baseplate. It is designed for bolting directly to a heatsink or cold plate with thermal compound or a phase-change pad. The package carries the 100 A average current without internal bond-wire bottlenecks, but the thermal resistance junction-to-case is the number that determines the real current derating — expect to keep the baseplate below 100°C to hold the 100 A rating. The four M4 screw holes are on a standard 38.2 mm x 25.4 mm pattern; verify the heatsink drill template matches before committing the mechanical layout. The base product number STTH200 covers a family of voltage and speed variants in the same ISOTOP footprint, so if a future revision needs a higher voltage rating (e.g., 600 V) the mechanical layout and heatsink stay the same.","metaTitle":"STTH200F04TV1 Fast Recovery Diode, 100A 400V ISOTOP","metaDescription":"STMicroelectronics STTH200F04TV1 fast recovery diode, 100A average rectified current, 400V reverse voltage, 80ns trr, 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":"STTH200","Capacitance @ Vr, F":"-","Supplier Device Package":"ISOTOP","Reverse Recovery Time (trr)":"80 ns","Current - Reverse Leakage @ Vr":"75 µA @ 400 V","Voltage - DC Reverse (Vr) (Max)":"400 V","Current - Average Rectified (Io)":"100A","Operating Temperature - Junction":"-55°C ~ 150°C","Voltage - Forward (Vf) (Max) @ If":"1.45 V @ 100 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$32.3400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/983818692a8d6ab447b029b0ffc0f08e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of STTH200F04TV1?","answer":"The reverse recovery time (trr) is 80 ns, measured at the specified test conditions.
