UIS & avalanche ratings
The unclamped inductive switching (UIS) rating has proven to be a useful parameter since becoming prevalent in MOSFET data sheets in the mid-1980s. While repetitive avalanching of the FET is not recommended in actual applications, engineers have learned to use this metric to avoid designing-in weaker devices that might cause issues.
