STGWA40S120DF3 Description

The STGWA40S120DF3 from STMicroelectronics is a high-performance 1200V, 40A trench field-stop IGBT housed in a TO-247-3L package. Designed for robust power switching applications, it features a low Vce(on) of 2.15V @ 15V, 40A, ensuring efficient conduction losses. With a collector current (Ic) rating of 80A and pulsed capability up to 160A, it delivers high current handling in demanding environments. The device exhibits fast switching characteristics, with turn-on/off delays (Td) of 35ns/148ns and a reverse recovery time (trr) of 355ns, optimized for high-frequency operation. Its switching energy (1.43mJ on, 3.83mJ off) and gate charge of 129nC further enhance efficiency in hard-switching topologies.
