Gas discharge tubes are sealed glass tubes consisting of a pair of electrodes filled with gas only to conduct when high voltage is applied across the electrodes. When there is a voltage spike, the gas is ionized, short-circuiting the energy away. Gas Discharge Tube Arresters (GDT) types can also be used to protect sensitive electrical circuit inputs from interference voltage transients that could be harmful. Gas discharge tubes disperse a tremendous amount of energy, making them an ideal choice for lightning surge protection, especially for telecommunications equipment.
Why Use a Gas Discharge Tube?
