The influence of different donors such as Nb, Ta, Sb, and V on nonlinear current (I)-voltage (V) relations of tin dioxide ceramics is investigated. The room-temperature resistivity (ρ), nonlinear coefficient (α), breakdown electric field (EB) and barrier height (ΦB) are calculated as a function of donor content. The present system contains fewer additives as compared to ZnO varistor wherein small quantities of variety of metal oxides are added. Optimum doping of antimony-doped samples shows promising behavior for low-voltage varistor application.
