MOV/GDT DEVICE HAVING LOW VOLTAGE GAS DISCHARGE PROPERTY

Electrical devices can be manufactured with a number of metal oxide varistors (MOVs) with each MOV including an external electrode on a first side of a metal oxide layer and an internal electrode on a second side of the metal oxide layer, and a layer of sealing material at or near a perimeter of the second side of the metal oxide layer of each MOV. A stack having one or more pairs can be provided, with each pair including two MOVs with their second sides facing each other such that the respective layers of sealing material engage each other, and the engaged layers can be fused to result in a seal that provides a sealed chamber of a gas discharge tube (GDT) between the two internal electrodes of each pair, with the seal having a thickness that is approximately same as a selected gap dimension between the two internal electrodes.
