In some embodiments, a gas discharge tube can include an insulator layer having first and second sides and defining an opening, and first and second electrodes that cover the opening on the first and second sides of the insulator layer, respectively. The gas discharge tube can further include a first glass layer implemented between the first electrode and the first side of the insulator layer, and a second glass layer implemented between the second electrode and the second side of the insulator layer, such that the first and second glass layers provide a seal for a chamber defined by the opening and the first and second electrodes.

Methods for fabricating gas discharge tubes. In some embodiments, a method for fabricating a gas discharge tube (GDT) device can include providing or forming an insulator substrate having first and second sides and defining an opening. The method can further include providing or forming a first electrode and a second electrode. The method can further include forming a first glass seal between the first electrode and the first side of the insulator substrate, and a second glass seal between the second electrode and the second side of the insulator substrate, such that the first and second glass seals provide a hermetic seal for a chamber defined by the opening and the first and second electrodes.

In some embodiments, a gas discharge tube (GDT) can include 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. The GDT can further include 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. The GDT can further include 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.

Provided is a gas discharge tube, including at least two electrodes and an insulating tube body, which is connected in a sealing manner with the electrodes to form a discharge inner cavity. A low-temperature sealing adhesive for sealing the discharge inner cavity is arranged in the gas discharge tube. The low-temperature sealing adhesive is melted at a specific low temperature to cause gas leakage in the discharge inner cavity.
