The 70 ns reverse recovery time keeps the switching loss manageable at frequencies up to several tens of kHz — above that the recovery charge starts to dominate the junction temperature rise. The 120 µA reverse leakage at 300 V is a room-temperature figure; expect it to multiply with junction temperature, so the heatsink design should keep the case below 125 °C for reliable operation. ## ISOTOP package — bolted-down thermal path for chassis-mount designs The ISOTOP package is a large, screw-terminal module designed for direct bolting to a heatsink or chassis wall. The two diodes share the same baseplate (common cathode), so the thermal interface is a single greased pad or phase-change film. Chassis mounting means the part is intended for permanent installation in an enclosure — not a PCB solder-down. The tube shipping medium is fine for prototype or low-volume builds; production quantities typically come in bulk trays. The base product number STTH12003 covers the family; the TV1 suffix denotes the specific voltage/package variant. For dual-sourcing resilience, the STTH12003TV2 is the same die in a different test-selection bin — functionally interchangeable in most designs, though the forward drop and recovery specs should be verified against the TV2 datasheet if swapping.","metaTitle":"STTH12003TV1 Fast Recovery Diode, 60A, 300V, ISOTOP","metaDescription":"STTH12003TV1 dual fast recovery diode, 60A per diode, 300V Vr, 70 ns 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":"STTH12003","Diode Configuration":"2 Independent","Supplier Device Package":"ISOTOP®","Reverse Recovery Time (trr)":"70 ns","Current - Reverse Leakage @ Vr":"120 µA @ 300 V","Voltage - DC Reverse (Vr) (Max)":"300 V","Voltage - Forward (Vf) (Max) @ If":"1.25 V @ 60 A","Current - Average Rectified (Io) (per Diode)":"60A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$22.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c746a0af2a2432ed9bd545ea513da2f9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STTH12003TV1/alternatives.json"},"ai":{"faq":[{"question":"Can STTH12003TV1 replace STTH12003TV2?","answer":"STTH12003TV1 and STTH12003TV2 are functionally the same die with different test-selection bins.
