Abstract

Provided is varistor ceramic. The varistor ceramic according to one embodiment of the present invention comprises praseodymia-based zinc oxide and strontium titanate (SrTiO3), wherein the atomic percent of strontium titanate ratio with respect to praseodymia-based zinc oxide is 92-99:8-1. Accordingly, the present invention improves ESD tolerance, has superb electrostatic capacity, and can exhibit stability in a heterojunction.
