Abstract: Disclosed herein is a ZnO-based varistor composition including zinc oxide (ZnO) as a main component and a calcium (Ca)-containing compound as an accessory component. The varistor composition provides excellent electrostatic discharge (ESD) characteristics because it has excellent physical properties, such as a nonlinear coefficient, a clamping voltage ratio, a surge absorbance and the like, and, particularly, does not include Bi2O3. Further, the varistor composition provides high work safety because it does not include Sb2O3 that is regulated for environmental purposes. Further, the varistor composition can reduce the manufacturing cost of a varistor because it does not Pr-based components that require high-temperature sintering and increase the manufacturing cost of a varistor. Particularly, the varistor composition has a low clamping voltage as well as a low capacitance.
