Abstract
A gas discharge tube includes a housing defining a chamber, first and second terminal electrodes mounted on the housing, a plurality of inner electrodes located in the chamber, and a gas contained in the chamber. The inner electrodes are serially disposed in the chamber in spaced apart relation to define a series of spark gaps from the first terminal electrode to the second terminal electrode. The chamber is hermetically sealed.
