With maximum junction temperature of 175 °C and low thermal resistance ensuring efficient dissipation, the STGWA30IH160DF2 has a current rating of 30 A and ensures long-term reliability in challenging environments.

Extending the STPOWER portfolio, this is the first 1600V IGBT in ST’s new IH2-generation. The devices leverage advanced trench gate field-stop (TGFS) technology to combine its high breakdown-voltage capability with low saturation voltage (V_CEsat) to minimize conduction losses. While the STGWA30IH160DF2 has V_CEsat of just 1.77 V (typical, at rated current), TGFS technology also minimizes tail current resulting in low turn-off energy. In addition, the anti-parallel diode has a low forward voltage and soft recovery that combine with the switching performance of the main transistor to ensure high efficiency in resonant and soft-switching topologies.

With these characteristics, the STGWA30IH160DF2 can be used in single-switch quasi-resonant converters over a wide switching frequency range, from 16 kHz to 60 kHz. The high breakdown voltage and thermal efficiency let the device withstand large voltage surges and spikes while minimizing reliance on external protective components, enabling a lower bill of materials (BOM).

Home appliances built with these IGBTs can compete strongly in price-sensitive markets, leveraging BOM savings, while the high efficiency lets new designs achieve outstanding energy ratings.

Also featuring a positive V_CE(sat) temperature coefficient with tight parameter distribution, the STGWA30IH160DF2 allows connecting multiple devices in parallel for current sharing in high-power applications.
