Optimised for conduction and switching performance in soft-switching circuits, STMicroelectronics’ STGWA40IH65DF and STGWA50IH65DF 650V STPOWER IGBTs increase the energy efficiency of resonant converters in the 16 kHz - 60 kHz switching frequency range.
Extending ST’s trench field-stop (TFS) IGBTs for soft-switching applications, which also include the HB and HB2 series for power supplies, welders and solar converters, the new IH-series devices are fine-tuned for the half-bridge circuits of appliances such as induction cookers and other soft-switching applications.
Rated for 40 A and 50 A, respectively, the STGWA40IH65DF and STGWA50IH65DF serve applications up to 4 kW. With low saturation voltage of 1,5 V (typical at nominal current) and a low-drop voltage freewheeling co-packaged diode, these IGBTs combine enhanced conduction performance with low turn-off losses of just 0,19 mJ in the 40 A 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 the saturation voltage for enhanced reliability. They are available now in the TO-247 long-lead power package, and will be joined by 20 A and 30 A variants in the near future, in TO-247 long lead and TO-220 packages.
