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.

Hear the CEOs of Infosys & HPE discuss the current crisis and how it has accelerated the need for digital transformation for their clients. Connectivity at the Edge, right mix of hybrid cloud, ability to extract data faster than ever before… these are just some of the contributions that HPE and Infosys make to our clients’ digital transformation journey.


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.
