Abstract
The present invention is to provide an improved surge protector device. The present invention's surge protector device basically has a plurality of metal bars which are combined to a single body by a continuous high-resistive film of semiconductor crystal so that there is no gap between adjacent metal bars; and electrodes formed on the endmembers of the said metal bars composing the single body. Thus, the present invention's surge protector device is fabricated so as to have no air gap between adjacent ones of the metal bars. As a result, the present invention's protector device can operate in such a way that the surge protector device changes from a non-conductive state to a conductive state due to breakdown in depletion region accompanying the semiconductor crystal when the voltage across the electrodes exceeds a threshold voltage because of a surge.
