Tyco Gas Discharge Tubes

Gas Discharge Tubes (GDTs) are placed in front of, and in parallel with, sensitive telecom equipment such as power lines, communication lines, signal lines and data transmission lines to help protect them from damage caused by transient surge voltages that may result from lightning strikes and equipment switching operations. These devices do not influence the signal in normal operation. However, in the event of an overvoltage surge, such as a lightning strike, the GDT switches to a low impedance state and diverts the energy away from the sensitive equipment.

Features & Benefits:

  • Wide range of voltages (75V-600V) and form factors
  • Low capacitance and insertion loss
  • Crowbar device with low arc voltage
  • High accuracy spark-over voltage for high precision designs
  • Devices tested per ITU K.12 recommendations
  • Optional fail-short mechanism
  • Provides overvoltage fault protection against damage caused by high energy surges
  • Suitable for sensitive equipment due to impulse spark over response
  • Suitable for high-frequency application
  • Highly reliable performance
  • Surface-mount devices for automated manufacturing

Applications:

  • MDF modules
  • xDSL equipment
  • RF systems
  • Antenna
  • Base stations
  • Power supplies
  • Surge protectors
  • Alarm systems
  • Irrigation systems
