2RD-8 SMD Type 8mmX6mm 2 Electrode 20KA Surge Arrester Gas Discharge Tube GDT For Power Supplies

2RD-8 SMD Type 8mmX6mm 2 Electrode 20KA Surge Arrester Gas Discharge Tube GDT for Power Supplies

Description of 2RD-8 SMD Type 8mmX6mm 2 Electrode 20KA Surge Arrester Gas Discharge Tube GDT

GDT is 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.

Our GDT 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 Main Distribution Frame (MDF) modules, high data-rate telecom applications (e.g. ADSL, VDSL), and surge protection on power lines. Their low capacitance also results in less signal distortion. When used in a coordinated circuit protection solution with PolySwitch devices, they can help equipment manufacturers meet stringent safety regulatory standards.
