Abstract The SnO2 varistor ceramic with good electrical performance was accomplished. The electrical properties of SnO2 varistor ceramics were systematically studied as a function of Mn2O3 doping between a loading range of 0.00 and 0.06 mol%. At a dopant of 0.04 mol%, a maximum nonlinear coefficient of 51 is obtained at a sintering temperature of 1400 °C, with the voltage gradient of 453 V/mm and leakage current of 4.2 μA/cm2.
