Overview: Gas Discharge Tube
2R075~2R800SA-6 Series
GDTs (Gas Discharge Tubes) are placed in front of, and in parallel with, sensitive tele equipment such as power lines, munication 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.
GDTs offer a high level of surge protection, a broad voltage range, low capacitance, and many form factors including new surface mount devices, which makes them suitable for applications such as MDF (Main Distribution Frame) modules, high data-rate tele applications (e.g. ADSL, VDSL), and surge protection on power lines. Their low capacitance also results in less signal distortion.
