Categories: Single IGBTs

Quality Control: Learn More

The Infineon Technologies IKW40T120FKSA1 is a TrenchStop® series NPT Trench Field Stop Insulated Gate Bipolar Transistor. This component features a maximum collector current (Ic) of 75 A and a pulsed collector current (Icm) of 105 A. It offers a collector-emitter breakdown voltage of 1200 V and a maximum power dissipation of 270 W. The device has a typical on-state voltage (Vce(on)) of 2.3V at 15V gate-emitter voltage and 40A collector current. The gate charge is 203 nC, with typical turn-on delay (Td(on)) and turn-off delay (Td(off)) of 48 ns and 480 ns respectively at 25°C. Reverse recovery time (trr) is 240 ns. Designed for through-hole mounting, it is supplied in the PG-TO247-3-1 package and is suitable for applications in industrial power supplies and motor control. Operating temperature range is -40°C to 150°C (TJ).
