  Electronic applications have progressed significantly in recent years and have inevitably

  increased the demand for an intrinsically rugged power MOSFET. Device ruggedness is

  defined by the capacity of a device to sustain an avalanche current during an unclamped

  inductive load switching event. However, the avalanche ruggedness performance of a

  power MOSFET is normally measured within the industry as a single-shot Unclamped

  Inductive Switching (UIS) avalanche energy or EAS. Whilst this provides an easy and quick

  method of quantifying the robustness of a MOSFET in avalanche, it does not necessarily

  reflect the true device avalanche capability (see Ref. 1, Ref. 2 and Ref. 3) in an

  application.
