ABSTRACT:
A material and device for electronic circuitry that provides protection from fast transient over-voltage pulses. The electroded device can additionally be tailored to provide electrostatic bleed. Conductive particles are uniformly dispersed in an insulating matrix or binder to provide material having non-linear resistance characteristics. The non-linear resistance characteristics of the material are determined by the inter-particle spacing within the binder as well as by the electrical properties of the insulating binder. By tailoring the separation between the conductive particles, thereby controlling quantum-mechanical tunneling, the electrical properties of the non-linear material can be varied over a wide range.
