Abstract
An electrical supply has a transient suppressor in which a transistor switch connects a resistor across the supply to dissipate an overvoltage condition. The control for the transistor switch turns the switch on at a first overvoltage condition and turns the switch off when the voltage drops to a level less than that of the first overvoltage level.
