2R800TD-8 800V Gas Discharge Tube – 2RD-8 Package | RUILON
RUILON
The 2R800TD-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect sensitive electronic circuits from high-energy transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Using advanced gas discharge technology, it provides ultra-fast response and stable long-term protection in harsh electrical environments.
With a DC spark-over voltage of 800V, this component is optimized for high-voltage surge protection applications requiring strong insulation coordination and excellent energy handling capability. Compared to lower-voltage GDT variants, it significantly reduces false triggering while ensuring robust suppression of severe transient surges. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs) for reliable protection under extreme 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 efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation, strong surge absorption capability, and long service life.
Encased in a compact 2RD-8 package, the 2R800TD-8 allows easy PCB integration for space-constrained 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.
