Surface-mount gas discharge tubes (GDTs) help protect high-speed xDSL modems, splitters, DSLAM equipment, AIO printers, base stations, and security systems from damage caused by overvoltage events. Compliant with various industry standards, products are available in 2- or 3-electrode versions and provide reliable, low-capacitance (0.5 pF min) protection for telecom/datacom applications. Key parameters include voltage range of 75-600 V and sizes from 3-8 mm.
Gas Discharge Tubes protect sensitive telecom equipment.

Jul 27, 2004 Raychem Circuit Protection Gas Discharge Tubes (GDTs) protect telecom equipment from damage due to transient surge voltages that typically result from lightning strikes and equipment switching operations. Placed in front of and in parallel with equipment, they act as high-impedance component while not influencing signal in normal operation. In case of overvoltage surge, GDTs switch to low-impedance state to divert energy away from sensitive equipment.
