Gas Discharge Tube Arresters (GDT)A gas discharge tube (GDT) is a type of circuit protection device that uses an ionized gas to interrupt or divert excessive electrical current. These devices are often used in high-voltage or high-frequency applications, where they can provide fast, reliable protection against overvoltages, surges, and transients.
GDT arresters, also known as GDT surge protectors, are a specific type of GDT that is designed to protect electronic circuits from overvoltages and surges. These devices are typically connected across the power or signal lines of a circuit, and they use their internal gas discharge mechanism to quickly and safely divert excessive electrical current away from the circuit.
GDT arresters are commonly used in a variety of applications, including power supplies, telecom and networking equipment, and industrial control systems. They are known for their fast response time, high surge capacity, and low capacitance, which makes them well-suited for protecting sensitive electronic circuits from overvoltages and surges.
