While the maximum junction temperature itself does provide a useful indication of the device’s resistance towards abnormal electrical events such as unclamped inductive switching (UIS) and short circuit (SC), fast thermal transients due to the high-power density are often what limits the reliability of the device, the metallization, and the packaging material[3].
