ABSTRACT:
An electrical overstress responsive composite is formed on an electrically insulative substrate, has a pair of electrodes associated with the substrate and defining a gap between the electrodes and over the interposed portion of the substrate, a pattern of closely spaced electrically conductive elements span said gap and are affixed to said substrate, and a dielectric resin overlies said conductive elements and also spans said gap. The dielectric resin may include conductive and/or semiconductive fine particles. The composite presents a high resistance to a low voltage applied across said electrodes and a low resistance to a high voltage applied across said electrodes.
