ABSTRACT:
An electronic circuit for protecting a field effect transistor from high voltage includes a switching device having a first state in which the switching device turns the field effect transistor ON, and a second state in which the switching device turns the field effect transistor OFF. A charging device is connected to the switching device and receives an electrical charge when an electrode of the field effect transistor is shorted to a voltage source. The charging device applies the electrical charge to the switching device to thereby place the switching device in the second state.
