Abstract
The present invention is directed to a varistor comprising a dielectric material comprising a sintered ceramic composed of zinc oxide grains and a grain boundary layer between the zinc oxide grains. The grain boundary layer contains a positive temperature coefficient thermistor material in an amount of less than 10 mol % based on the grain boundary layer.
