Abstract

A metal oxide varistor having an alpha in excess of 10 in the current density range of from 10<->3 to 102 amperes per square centimeter is formed with laterally spaced electrodes adjacent a first surface. A spaced third electrode may be associated with the first surface or a second surface. To improve the current carrying capacity of the varistor body the conduction gap between the electrodes may extend along the first surface an extended distance greater than the width of the surface. The conduction gap width may be varied continuously or in discrete steps. [US3768058A]
