IGBTs Support Soft Switching

STMicroelectronics’ STGWA40IH65DF and STGWA50IH65DF 650V STPOWER IGBTs are said to be optimized for best conduction and switching performance in soft-switching circuits. The latest IH-series devices increase the energy efficiency of resonant converters in the 16- to 60-kHz switching-frequency range. They are fine-tuned for the half-bridge circuits of appliances such as induction cookers and other soft-switching applications.


Rated for 40A and 50A, respectively, the STGWA40IH65DF and STGWA50IH65DF suit applications up to 4 kW. With a saturation voltage (VCE(sat)) of 1.5V (typical at nominal current) and a low-drop voltage freewheeling co-packaged diode, the IGBTs specify turn-off losses of 0.19mJ (typical) in the 40A STGWA40IH65DF.

IH-series IGBTs are specified up to the maximum junction temperature of 175°C, and feature low thermal resistance and a positive temperature coefficient of VCE(sat) for enhanced reliability. The STGWA40IH65DF and STGWA50IH65DF IGBTs are available now in the TO-247 long-lead power package. The company will add 20A and 30A versions soon in TO-247 long lead and TO-220 packages. For more specs and cosmic wisdom, pursue and peruse the STGWA40IH65DF and STGWA50IH65DF datasheets.
