WebIGBT typically works in the saturation region during the normal ON state. When a short circuit happens, the collector current IC increases and goes through a sharp transition from the saturation region to the active region. The collector current gets self-limited and becomes independent of VCE. Consequently, the increase in IGBT current and power
