It is also called as nonpunch through IGBT	It is also called as punch through IGBT
The $n^+$ buffer layer is absent in the structure	The $n^+$ buffer layer is present in the structure
The IGBT have slower turn off	The IGBT have faster turn off
The IGBT can block the forward and reverse anode to cathode voltage successfully. They have symmetrical blocking capability	These IGBT can block only the forward anode to cathode voltage successfully. They have an asymmetrical blocking capacity
