Abstract

It has been understood that a single pulse operation is limited by the maximum junction temperature, T_j,max. The intrinsic nature of the maximum junction temperature limit is expressed in terms of power but not of voltage. Both simulation and experimental results reveal that the maximum junction temperature is not static but dynamic, depending on the voltage. The intrinsic junction temperature mechanism can not comprehend the dynamic property of the maximum junction temperature. This paper deals with dynamic characteristics of the maximum junction temperature of power MOSFET devices in terms of operation and design aspects.
