FAQ about Gas Discharge Tube Arresters (GDT)

1. What is a gas discharge tube arrester?
A gas discharge tube arrester is a device that uses the principle of gas discharge to achieve overvoltage protection. It is mainly composed of a ceramic sealed discharge tube, which contains two or more metal electrodes with gaps and is filled with inert gas such as argon or neon. When the external voltage exceeds the breakdown voltage of the discharge tube, the gas in the tube is ionized under the action of the electric field to form a conductive channel, which quickly discharges the large current and high voltage generated by the lightning strike, thereby protecting the subsequent circuit from damage. Once the overvoltage disappears, the discharge tube will return to a high-resistance insulation state, waiting for the next impact.

2. What is the difference between GDT and MOV?
GDT (gas discharge tube) and MOV (varistor) each have their own characteristics and applicable scenarios in circuit protection.
Working Principle and Characteristics
GDT: GDT is a switching overvoltage protection component with the characteristics of large flow rate, large inter-electrode insulation resistance, slow response speed and small parasitic capacitance. It is often used in high-frequency electronic circuit protection, especially as the first or second level protection in multi-level protection circuits. The working principle of GDT is to limit the voltage through gas discharge. When the voltage reaches a certain threshold, the gas in the gas discharge tube is ionized, thereby conducting the current and protecting the subsequent circuit.
MOV: MOV is a clamping type overvoltage protection component with large flow rate, slow response speed and large parasitic capacitance. MOV uses its nonlinear characteristics to clamp the voltage to a relatively fixed voltage value when overvoltage occurs, thereby protecting the subsequent circuit. The main materials of MOV are divalent element zinc and hexavalent element oxygen, and its nonlinear characteristics are used to limit the voltage. -
3. What are the advantages and disadvantages of GDT?
Advantages: before breakdown, it is equivalent to an open circuit, with high resistance and low leakage current; after breakdown, it can pass a large current with low voltage drop; the pulse flow rate is large, and the commonly used specifications are 2KA, 10KA, 20KA, etc., and the highest can reach more than 100KA; the junction capacitance is low, and most of them are less than 2pF.
Disadvantages: The response speed is slow, generally 0.2~0.3 microseconds, and the fastest is about 0.1 microseconds; the breakdown voltage consistency is poor, the dispersion is large, generally ±20%; the breakdown voltage has only a few specific values.
