Analysis of the p-n junction second breakdown mode†

Abstract A theoretical and experimental investigation of the p-n junction second breakdown mode is roported. By means of two simple models expressions are derived for the second breakdown terminal voltage which indicate the influence of device heat-sink conditions on the observed current-voltage characteristics in the low-voltage mode. Various experimental results are presented in support of the theoretical work, and a method is suggested for estimating maximum possible constriction temperatures.
