V2O5/Mn3O4/Nb2O5 codoped zinc oxide varistor ceramics were sintered at a temperature range as low as 875~950°C. The voltage clamping characteristics of V2O5/Mn3O4/Nb2O5 codoped zinc oxide varistor ceramics were investigated at a pulse current range of 1~50 A. The sintering temperature had a significant effect on clamp voltage ratio, which exhibits surge protection capabilities. The varistor ceramics sintered at 875°C exhibited the best clamping characteristics, in which the clamp voltage ratio was 2.69 at a pulse current of 50 A. The varistor ceramics sintered at 900°C exhibited the highest electrical stability, where = 3,824 V/cm (initial 3,909 V/cm), and E1 mA/cm2 = 27 (initial 39) after application of a pulse current of 100 A.
