Gas Discharge Tubes (GDTs) are installed in front of and connected in parallel with sensitive telecommunications equipment — such as power lines, communication lines, signal lines, and data transmission lines — to help protect these devices from transient surge voltages that may be caused by lightning strikes and equipment switching operations. Under normal operating conditions, these devices do not affect signal transmission. However, when an overvoltage surge occurs (such as a lightning strike), the GDT switches to a low-impedance state, diverting energy away from sensitive equipment.

Our GDTs offer high-level surge protection, a wide voltage range, low capacitance, and are available in a variety of package sizes, including new SMD devices. This makes them suitable for applications such as Main Distribution Frame (MDF) modules, high data rate telecommunications applications (e.g., ADSL, VDSL), and surge protection on power lines. Their low capacitance also reduces signal distortion. When used in conjunction with PolySwitch devices in coordinated circuit protection solutions, they can help equipment manufacturers meet stringent safety regulatory standards.
