condition
Abstract Power MOSFETs are normally measured based on single-shot
Unclamped Inductive Switching (UIS) avalanche energy. This note
describes in detail the avalanche ruggedness performance, fundamentals
of UIS operation and appropriate quantification method for the safe
operating condition.
