It is designed for medium-frequency hard-switching applications such as motor drives, inverters, and PFC stages where low conduction loss and fast switching are both required. The Trench Field Stop structure delivers a low saturation voltage of 2 V at 40 A and 15 V gate drive, which directly reduces conduction losses in the on-state. The co-packaged diode has a 62 ns reverse recovery time, helping to contain turn-on losses in bridge topologies. ## Switching losses and gate drive budget Total gate charge is 210 nC. The 498 µJ turn-on and 363 µJ turn-off energy at 400 V, 40 A, 5 Ω gate resistor define the switching loss contribution to the thermal budget. Turn-on delay is 40 ns and turn-off delay is 142 ns at 25 °C; these numbers set the minimum dead-time in a half-bridge leg to avoid shoot-through. The 160 A pulsed collector current rating gives headroom for inrush and fault conditions. ## Thermal and environmental range Maximum power dissipation is 283 W, but the real thermal limit depends on the heatsink and the RthJC of the TO-3P package.","metaTitle":"STGWT40H65DFB IGBT, 650V 80A Trench Field Stop, TO-3P","metaDescription":"STGWT40H65DFB 650V 80A Trench Field Stop IGBT in TO-3P.
