Abstract: A metal oxide varistor comprises a ceramic substrate having a first and second surface that form a spiral, and first and second conductive coatings disposed thereon that are in electrical contact with respective electrodes. A cavity is defined between the conductive coatings to preclude shorting the device, and a non-conductive material is disposed in the cavity to prevent arcing.

Abstract: A metal oxide varistor comprises a hollow ceramic body having an opening, a first electrode within the body and having a portion extending through the opening, and a second electrode disposed on the exterior surface of the body. Voltage applied to the electrodes above the device clamping voltage causes the ceramic body to conduct. The geometry of the body, which is optimally a sphere, greatly increases surface area between the electrodes and the ceramic body, and consequently increases the device's current carrying capacity.
