2R2000T 2000V Gas Discharge Tube (GDT) Surge Protector – 2R-8T Package | RUILON

The RUILON 2R2000T Gas Discharge Tube (GDT) is a high-performance ceramic surge protection device engineered to protect sensitive electronic systems from damaging transient overvoltage events. With a DC spark-over voltage of 2000V, this GDT provides fast, reliable response to lightning surges, switching transients, and electrostatic discharge (ESD), ensuring stable and safe operation of critical electronic circuits.

Designed using advanced gas discharge technology, the 2R2000T features ultra-low capacitance and high insulation resistance, making it ideal for high-speed communication lines, signal transmission systems, and precision electronic applications. It effectively diverts high-energy surge currents away from sensitive components while preserving signal integrity and minimizing interference.

Compared with lower-voltage protection components, this 2000V-rated GDT delivers improved surge handling capability, reduced false triggering, and enhanced durability under repeated high-energy impulse conditions. Its ceramic-sealed construction ensures stable glow and arc voltage behavior, excellent thermal performance, and long operational service life even in harsh environments.

The compact 2R-8T package (1000–6000V series range) supports flexible design integration for multi-level surge protection architectures while maintaining space-efficient PCB layouts. The RUILON 2R2000T is widely used in telecommunications equipment, industrial automation systems, power supplies, smart grid applications, and outdoor electronics where high-voltage surge protection and long-term reliability are essential.
