STMicroelectronics STGW30N120KD and STGW40N120KD: IGBTs use less energy than typical motor drives

The 30A STGW30N120KD and 40A STGW40N120KD IGBTs have low energy loss when conducting and switching. The devices come in TO-247 packages, which reduce component count by integrating ultrafast freewheeling diodes. Operating at 1200V, the transistors use high ac-line voltages, such as 440 or 480V, and can survive 10-µsec short circuits. The 30 and the 40A W40N120KD IGBTs cost $2.50 and $2.80 (5000), respectively.
