2R800TB-8 800V Gas Discharge Tube – 2RB-5 Package | RUILON
RUILON
The 2R800TB-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard electronic circuits from high-energy transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it ensures fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 800V, this component is optimized for high-voltage applications requiring strong insulation and robust surge handling capability. Compared to lower-voltage GDT variants, it significantly reduces false triggering while maintaining effective protection against severe transient surges. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs), ensuring reliable operation in harsh electrical conditions.
The device features low capacitance at 1 MHz, helping preserve signal integrity in high-speed communication systems, while high insulation resistance minimizes leakage current and improves overall system efficiency. Stable glow voltage and arc voltage characteristics ensure consistent performance and long service life even under repeated surge events.
Encased in a compact 2RB-5 package, the 2R800TB-8 is easy to integrate into space-constrained PCB designs. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
