Abstract
Disclosed is an electrostatic discharge device, typically referred to as a power clamping circuit, for minimizing the effects of an initial ESD event as well as providing protection against subsequent ESD events. The power clamp is left fully turned on during and after an ESD event. Subsequent ESD events are those ESD events occurring shortly after an initial ESD event. By using a blocking device such as a diode, the power clamping circuit is maintained in a strong 'on' state that fully discharges the initial ESD event and allows for a more rapid response to subsequent ESD events.
