Gas Discharge Tubes - GDTs / Gas Plasma Arrestors

Gas Discharge Tubes (GDTs), also known as Gas Plasma Arrestors, are essential components designed for the protection of electronic circuits from transient voltage surges. These specialized tubes function as reliable and fast-acting devices, safeguarding sensitive equipment from damage caused by sudden spikes in voltage. GDTs operate on the principle of gas ionization within a sealed tube. When exposed to a high voltage surge, the gas inside the tube ionizes, creating a low-resistance path for the excess energy to safely dissipate. This process effectively diverts the surge away from the connected circuit, preventing potential damage to electronic components.
