650 V, 8 A Trench Field Stop IGBT for power conversion
The STMicroelectronics STGF4M65DF2 is a Trench Field Stop IGBT from the Series M family, rated for 650 V collector-emitter breakdown and 8 A continuous collector current in a TO-220FP full-pack through-hole package. Gate charge is 15.2 nC.
Switching performance and thermal budget
Tested at 400 V bus, 4 A load, 47 ohm gate resistor and 15 V gate drive, the turn-on switching energy is 40 µJ and turn-off is 136 µJ — the asymmetric loss favours resonant or soft-switching designs where turn-off dominates. Turn-on delay is 12 ns and turn-off delay 86 ns at 25°C junction, giving a usable switching range into the low tens of kHz before thermal limits are reached in a hard-switched PFC or inverter stage. Maximum power dissipation is rated at 23 W — the TO-220FP full-pack package isolates the tab electrically, so no insulating pad is needed, but the thermal path to the heatsink is through the plastic back, which adds thermal resistance versus a standard TO-220.
