Abstract
In accordance with an embodiment, a method of operating a transistor includes: switching the transistor on and off based on a control signal; monitoring a voltage of a collector node of the transistor; detecting whether the voltage of the collector node of the transistor is above a first threshold; and after detecting the voltage of the collector node of the transistor above the first threshold, regulating a voltage across a load path of the transistor to a first target voltage.
