Low Capacitance Gas Discharge Tubes - SX5 Series DC Spark-Over Voltage : 70~5000V​

SX5 0 - 230X SMDT.pdf

Gas discharge tube is a gap-type lightning protection component, which has been widely used in lightning protection of communication systems. The discharge tube is often used in the first or first two stages of a multi-level protection circuit to discharge lightning instantaneous overcurrent and limit overvoltage. Since the inter-electrode insulation resistance of the discharge tube is large and the parasitic capacitance is small, it is not suitable for high frequency Lightning protection for signal lines has definite advantages. The main shortcomings of the protection characteristics of the discharge tube are that the discharge time delay is large, the action sensitivity is not ideal, and it is difficult to effectively suppress the lightning wave with a steep rise of the wave head, and there is a freewheeling problem in the lightning protection of the power system.

Commonly used gas discharge tubes include two-electrode discharge tubes and three-electrode discharge tubes. Most of the packaging shell materials are ceramics, so they are called ceramic discharge tubes.

Principle

The working principle of the discharge tube is gas gap discharge. When a certain voltage is applied between the two poles of the discharge tube, an uneven electric field is generated between the electrodes: under the action of this electric field, the gas in the tube begins to dissociate. When the applied voltage increases to make the gap between the electrodes When the field strength exceeds the dielectric strength of the gas, the gap between the two poles will be broken down by the discharge, and the original insulating state will be transformed into a conductive state. After the conduction, the voltage between the two poles of the discharge tube will remain at the residual voltage level determined by the discharge arc. , this residual voltage is generally very low, so that the electronic equipment connected in parallel with the discharge tube is protected from overvoltage damage
