ST Launches IGBT Optimized for Soft Switching
Published2019.03.29 09:01| Adjust to fit home appliance half-bridge circuits, etc.
Supports a maximum junction temperature of 175℃ and has low thermal resistance
STMicroelectronics announced on the 26th that it has launched the 650V STPOWER IGBTs 'STGWA40IH65DF' and 'STGWA50IH65DF', which are optimized for the switching performance and high conductivity of soft-switching circuits. The new products can improve the energy efficiency of resonant converters in a switching frequency range of 16 kHz to 60 kHz.
650V IGBT IH Series
The new IH series devices are one of ST's TFS (Trench Field-Stop) IGBTs for soft-switching applications, and include the HB and HB2 series for power supplies, welders, and solar converters. This device has been finely tuned for half-bridge circuits in home appliances such as induction cookers and other soft-switching applications.
STGWA40IH65DF and STGWA50IH65DF support applications up to 4 kW with ratings of 40 A and 50 A, respectively.
The two IGBTs provide excellent conduction performance as freewheeling co-packaged diodes with a low saturation voltage (VCE(sat)) of 1.5V (average at nominal current) and a low drop voltage, as well as a low turn-off loss of 0.19mJ (average) at 40A STGWA40IH65DF.
The IH series IGBT supports a maximum junction temperature of 175°C and features low thermal resistance and a positive temperature coefficient VCE(sat), adding to reliability.
STGWA40IH65DF and STGWA50IH65DF IGBTs are currently available in TO-247 LL (Long-Lead) power packages. Products supporting 20A and 30A will also be released soon in TO-247 LL and TO-220 packages.

STMicroelectronics Launches Smart Antenna Controller to Boost Smartphone Performance
STMicroelectronics has launched the STHVDAC-253C7, a digital controller for variable capacitors such as its STPTIC product line. This controller reduces the size, material cost, and power consumption of antenna tuning circuits while stabilizing RF performance in smartphones. When the STHVDAC-253C7 is used together with STPTIC capacitors for impedance matching and frequency tuning, the effects caused by environmental changes can be nearly completely eliminated. As a result, signal reception becomes stronger, call drops are reduced, data speed increases, and mobile phone battery life is extended.
