2R470D-8S 470V Gas Discharge Tube – 2RD-8S Package | RUILON
RUILON
The 2R470D-8S Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect electronic circuits from high-energy transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Utilizing advanced gas discharge technology, it ensures fast response and stable long-term performance in demanding environments.
With a DC spark-over voltage of 470V, this component is well-suited for medium to high-voltage applications, offering enhanced system stability and reduced risk of false triggering compared to lower-voltage GDT variants. It supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it ideal for surge-prone electrical environments.
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication systems, while high insulation resistance minimizes leakage current and improves efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation and extended service life.
Encased in a compact 2RD-8S package, the 2R470D-8S allows easy integration into various PCB layouts. 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.
