It targets hard-switching applications such as motor drives, UPS inverters, and welding converters where the 1200 V collector-emitter breakdown voltage provides margin for 400 VAC to 690 VAC bus rails, and the 75 A continuous collector current supports 10–30 kW output stages with appropriate heatsinking. ## Conduction and switching losses at the operating point At the test condition of 600 V, 40 A, 15 Ω gate resistor, and 15 V gate drive, the typical Vce(on) is 2.3 V — this on-state voltage sets the conduction loss floor. For a 40 A rms phase current, the conduction loss per device is roughly 92 W, which must be sunk by the heatsink. The total switching energy per cycle is 6.5 mJ; at a 10 kHz switching frequency that adds 65 W of dynamic loss, pushing the junction toward the 270 W power-max ceiling. The 240 ns reverse recovery time on the co-packaged diode is fast enough for most IGBT switching speeds but should be verified against the diode's own recovery losses in the target topology. ## Temperature range and thermal design The operating junction temperature range is -40 to 150 °C. The 150 °C maximum junction is typical for TrenchStop IGBTs and allows a reasonable thermal headroom above the 125 °C limit of older planar devices. The turn-on delay is 48 ns and turn-off delay is 480 ns at 25 °C; the turn-off tail is the dominant switching loss contributor at higher junction temperatures. Gate charge is 203 nC — a standard 15 V gate driver with 2 A peak source/sink can charge and discharge the gate in under 100 ns, keeping switching edges clean.","metaTitle":"Infineon IKW40T120FKSA1 IGBT, 1200 V 75 A TO-247-3","metaDescription":"Infineon TrenchStop IGBT, 1200 V Vces, 75 A Ic, 2.3 V Vce(on) at 40 A.
