Abstract :
The energy between the beginning of turn-off and the onset of second breakdown, dissipated at the collectors of power transistors switching inductive loads, was determined and plotted vs. the time to second breakdown. A linear relationship was obtained, excluding a thermal initiation mechanism, which requires a t½ dependence.
