New planar technology concept results in a tighter variation of switching energy (EOFF) versus temperature

The new family of ultra-fast (W series) 600 V HF IGBTs improves the power efficiency in highfrequency equipment by minimizing turn-off energy losses mainly at frequencies up to 100 kHz. The new series, which includes 35 A (STGWx35HF60WDx) and 45 A (STGWx45HF60WDx) devices,
facilitates parallel connection for higher power levels as a result of the VCE(sat) classification. It also achieves up to 10% better performance in conduction and switching losses, and lower spread of dynamic parameters, even at high temperature compared to the previous generation products.
