WebPunch through IGBT. The Punch through IGBT includes N+ buffer layer due to which it is also known as an asymmetrical IGBT. They have asymmetric voltage blocking capabilities i.e. their forward and reverse breakdown voltages are different. Their reverse breakdown voltage is less than its forward breakdown voltage. It has faster switching speed. Webdiode in the power circuit affect IGBT turn-on loss. For NPT IGBTs, turn-off speed and switching loss remain relatively constant over the operating temperature range. For PT IGBTs, turn-off speed degrades and switching loss consequently increases with temperature. However, switching loss is low to begin with due to tail current quenching.
