High-voltage gas pipe for relay protection

High voltage gas discharge tubes (GDT) provide overvoltage protection to components and circuits in electronic equipment. They include spark gaps; simple devices with two or three conducting electrodes separated by a gap filled with a gas such as air. They offer very high surge capability, low leakage, and extremely low capacitance, making them a key building. High voltage relays are electromechanical devices whose purpose is to switch to high voltage signals (> 1kV) and high frequency applications. These relays are heavily insulated and are made of strong materials to increase contact life. Bourns® GDTs are used in primary and secondary applications and can withstand multiple applications of high surge current energy in excess of 25 KA.
