Abstract
An electrostatic discharge (ESD) damage prevention device is comprised of a spark gap coupled in series with a high-impedance network, with a first node of the series combination of the spark gap and high-impedance network coupled to a conductive location that may be subject to an electrostatic discharge and the second node coupled to a conductor capable of conducting away charge delivered by an ESD event. The spark gap defines the level of electrical isolation and the high-impedance network controls dissipation of charge delivered by an ESD event.
