Abstract
This paper deals with the surge protective devices to minimize damages of communication equipments in signal data lines. The basic circuit consists of zener diodes, spark gap and series impedances. Therefore the hybrid circuit using bipolar zener diodes as clamps and a three-electrode spark gap as crowbars was proposed. The surge suppression performances and the characteristics of frequency response were investigated experimentally. Consequently, it was found that the frequency bandwidth and surge suppression performances are excellent.
