One of the critical requirements for high power devices is to have rugged and reliable capability against hash operating conditions. In this paper, we present the dynamic voltage clamping capability of 3.3kV Field Stop Clustered IGBT devices under extreme inductive load condition. It shows that PMOS trench gate CIGBT structure with outstanding performance of fast turn-off time and low over-shoot voltage. Further optimization of current gain of CIGBT structure is analyzed through numerical evaluation. A step further in the safe operating area has been achieved for high voltage devices by CIGBT technology.
