It is designed for hard-switching power conversion in industrial drives, UPS systems, and welding inverters where 1200 V bus voltage isolation and 150°C junction capability are required. ## Conduction and switching losses at the operating point At the test condition of 600 V bus, 25 A collector current, 22 Ω gate resistor, and 15 V gate drive, the IGW25T120FKSA1 delivers a Vce(on) of 2.2 V typical and a total switching energy of 4.2 mJ. The 155 nC gate charge sets the drive current requirement — a typical gate driver with 2 A peak source/sink capability will switch this device in the 50 ns turn-on / 560 ns turn-off window at 25°C. The 190 W maximum power dissipation in the TO-247 package means the thermal interface to the heatsink is the limiting factor for continuous current — expect to derate from the 50 A Ic rating in real-world enclosures above 100°C case temperature. ## Package, mounting, and temperature grade The PG-TO247-3-1 supplier package is a standard TO-247 with three leads and an isolated mounting hole. The through-hole leads require a 0.040-inch (1.0 mm) drilled hole per lead in the PCB, with adequate creepage distance — at 1200 V working voltage, 6.4 mm minimum clearance per IEC 60950 is typical between collector tab and any grounded heatsink. Rated for continuous junction operation from -40°C to 150°C, this IGBT suits outdoor telecom rectifiers, solar inverter DC-AC stages, and motor drive output stages where the ambient may cycle below freezing. ## Lifecycle and compliance status ROHS3 compliant, with no lead in the solder plating or mould compound. No official second-source or pin-compatible replacement is listed; the TrenchStop series is Infineon's own platform, so cross-shopping a competitor's TO-247 IGBT requires verifying the gate threshold voltage window and the switching energy trade-off at the same test condition.","metaTitle":"Infineon IGW25T120FKSA1 IGBT, 1200 V 50 A TO-247-3","metaDescription":"Infineon TrenchStop IGBT, 1200 V Vces, 50 A Ic, 2.2 V Vce(on) at 25 A, 155 nC Qg, TO-247-3.

This value determines the average gate drive current needed at the target switching frequency — for example, at 20 kHz switching, the average drive current is 3.1 mA per device."},{"question":"What is the closest pin-compatible alternative to the IGW25T120FKSA1?","answer":"No official pin-compatible second source or replacement is listed in the component record.
