The low voltage and voltage polarity problems were solved by using a unique Zn-Bi- Ti - Sn formula system and firing silver technology of 850℃. Obtained products have following advanta- ges:voltage gradient (20V/mm), voltage polarity(〈1V), nonlinear coefficent (〉30), leakage current (〈5μA),clamp voltage ratio(1.5,2.5A). The devices of Φ10mm chip have a peak lightning current (1300A,8/20μS), the varistor voltage change ratio(-3%). The products were achieved industrialization.
