What are the Main Parameters of GDT Gas Discharge Tubes? Usage Precautions?

GDT Gas Discharge Tube is an electrical protection component used to safeguard electronic equipment. Its main parameters include:

1. Rated Voltage: The operating voltage range of the gas discharge tube.

2. Leakage Current: The leakage current of the GDT gas discharge tube under a fixed voltage.

3. Strike Voltage: The voltage value at which the GDT gas discharge tube begins to conduct and discharge electricity.

4. Holding Current: The current value during the normal operation of the gas discharge tube.

5. Time to Protection Current/Voltage: The response time for the gas discharge tube to ultimately activate under protective current and voltage conditions.

When using GDT gas discharge tubes, the following points should be noted:

2. Gas discharge tubes are typically installed at the entry point of the circuit to be protected to provide optimal circuit protection.

3. After the GDT gas discharge tube conducts and discharges, its internal capacitor will discharge, generating a momentary high voltage. Therefore, proper grounding and guiding of wires should be maintained, and direct contact should be avoided.

4. Do not arbitrarily modify the parameters of the gas discharge tube or attempt to disassemble or repair it to avoid electrical hazards.

5. Correctly selecting and using GDT gas discharge tubes can significantly enhance the voltage resistance of electronic products, reduce circuit failures, and extend the service life of electronic devices.
