ABSTRACT:
A material and device for electronic circuitry that provides protection from fast transient over-voltage pulses. Conductive particles are dispersed in an insulating matrix to provide material having foldback switching characteristics. The foldback switching characteristics of the material are determined by the spacing between the conductive particles (which must be at least 1000 Angstroms) as well as by the electrical properties of the insulating matrix.
