Abstract : The patent application provides an improved method for determining the damage threshold of a semiconductor p-n junction. It uses a constant current pulse so that when second breakdown begins the power applied to the device junction is decreased. The power applied up to the point of second breakdown is constant and easily determined from the oscilloscope traces of voltage and current. In addition, the power is clearly more indicative of the power handling capabilities of the device's p-n junction.
