GDT — Gas Discharge Tube

Gas Discharge Tubes (GDTs) are high-performance surge protection components that divert excessive voltage to ground through an ionized gas path. They offer ultra-fast response time, high isolation, and strong surge-handling capability, making them ideal for applications in telecom lines, industrial equipment, and power systems.

FTR’s GDT series is developed using robust ceramic-metal sealing technology, ensuring excellent durability and environmental resistance. These components comply with IEC 61643 standards and support global safety approvals including UL and RoHS.
