The RUILON 2R1000T-8T Gas Discharge Tube (GDT) is a high-performance ceramic surge protection device designed to safeguard sensitive electronic circuits from transient overvoltage events. With a DC spark-over voltage of 1000V, this GDT ensures fast and reliable response to lightning surges, switching transients, and electrostatic discharge (ESD), providing strong protection for modern electronic systems.
Engineered with advanced gas discharge technology, the 2R1000T-8T features ultra-low capacitance and high insulation resistance, making it ideal for high-speed communication lines, signal interfaces, and precision electronic applications. It effectively minimizes signal distortion while safely diverting high-energy surge currents away from critical components.
Compared with lower-voltage protection solutions, this 1000V-rated GDT delivers improved surge endurance, reduced false triggering, and enhanced stability under repeated high-energy impulse conditions. Its ceramic-sealed construction ensures excellent thermal stability, consistent glow and arc voltage characteristics, and long operational life in demanding environments.
The versatile 2R-8T package (1000–6000V series range) allows flexible design integration across multiple protection levels while maintaining compact PCB footprint efficiency. The RUILON 2R1000T-8T is widely used in telecommunications equipment, industrial automation systems, power supplies, smart metering devices, and outdoor electronics, where robust surge protection and long-term reliability are essential.
