Abstract :
Two shapes of interdigitated planar varistors were made using thick-film technology on alumina substrates. These varistor were based on ZnO paste. The distance between varistor electrodes were changed from 0.2 to 1.91 mm, and the total length of the electrodes from 49 to 230 mm. The varistor threshold voltages were obtained in the region of 1100-3100 VAC. The threshold voltages were proportional to the distance between electrodes. The influence of electrode geometry on U- I characteristics was analyzed
