| Parameter | ||
|---|---|---|
| Supply voltage | - | Same class; same gate-network review applies. |
| Memory & Peripherals | - | Choose by topology: resonant welder and induction stages pull the gate and diode differently from hard-switched converters - match the generation to the circuit. |
| Case | TO-3P (EIAJ SC-65) / TO-247 | TO-247 |
| Compatibility Level | - | Pin-to-Pin (Minor Clock/Init Tuning) |
| Component Category | IGBTs (Discrete) | - |
| Core & Architecture | - | TrenchStop 2 in the same 1200V/25A class, tuned toward frequency converter and UPS duty - the second viable replacement lane when one generation is short. |
| Firmware Notes | - | Same substitution rule as the H3: the socket always fits; the gate network and free-wheel diode behavior are the review. |
| Hardware Notes | - | TO-247 DuoPack with the co-packed diode. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The 25N120 is the 1200V, 25A IGBT that anchors the power stage of welder inverters, induction heating boards and inverter supplies: a TO-3P body (the onsemi FGA25N120ANTD) or a TO-247 body (the Infineon IKW25N120), gate-collector-emitter in one shared order, a free-wheel diode co-packed, and a market full of mystery-grade 25N120 clones whose saturation voltage gives them away. The onsemi datasheet now carries a discontinued marking, which quietly moves this staple toward last-time-buy sourcing - and that is where verified, photographed stock becomes the difference between a repair and a comeback. | - |
| Reference Part | - | FGA25N120 |
| Role In Circuit | Original Reference Part | - |
| Sourcing Advantage | - | Stocked alongside the H3; quote both generations against one BOM. |
| Sourcing Status | Active Shenzhen Spot Sourcing (24–48h) | - |
