Specialized Resistors

GDTSurge ProtectionTelecom

The 3R090TB-8 is a 3-electrode gas discharge tube (GDT) optimized for high-speed telecom and data line surge protection, offering 90V DC spark-over and 10kA surge capacity.

Best for

  • Telecom line protection
  • ADSL/VDSL equipment
  • Data transmission lines

Avoid if

  • Applications where operating voltage exceeds 90V DC
  • High-frequency signal paths sensitive to parasitic capacitance

Check before use

  • Ensure the circuit's maximum operating voltage is below the GDT's spark-over threshold.
