1. A gas discharge tube (GDT) comprising:
first and second electrodes each including an edge and an inward facing surface, such that the inward facing surfaces of the first and second electrodes face each other;
a sealing portion implemented to join and seal the edge portions of the inward facing surfaces of the first and second electrodes to define a sealed chamber between the inward facing surfaces of the first and second electrodes; and
an electrically insulating portion implemented to provide a surface in the sealed chamber and to cover a portion of the inward facing surface of each of at least one of the first and second electrodes such that a leakage path within the sealed chamber includes the surface of the electrically insulating portion.
