  • Surge arrester
    Patent number: 5781393
    Abstract: A surge arrester which includes a pair of spaced metal electrodes and a semiconductor element interposed between the metal electrodes and in contact with at least one of the metal electrodes. The semiconductor element functions at least partially to bridge a gap between the metal electrodes with such gap serving as a current path between the metal electrodes in the event a voltage applied across the metal electrodes exceeds a firing voltage of the surge arrester. The semiconductor element includes a metal coating on at least a substantial portion of its outer surface which is in contact with the at least one metal electrode. The coating includes a gap between the electrodes and the gap may include a notch in the gap.
