Abstract
An ESD protective device having a low capacitance and stability characteristics constructed by installing a voltage sensitive material between electrodes. The voltage sensitive material comprises a fluorescent substance. The voltage sensitive material may be barium aluminate. The voltage sensitive material may be zinc silicate. The voltage sensitive material may be zinc sulfide. The voltage sensitive material is doped with a metal atom such as Mn, Cu and Eu. The device does not distort a signal wave pattern and have low capacitance of 0.5 pF or lower.
