2R470B-8S 470V Gas Discharge Tube – 2RB-8S Package | RUILON
RUILON
The 2R470B-8S Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device engineered 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 rapid response and stable, long-term protection in demanding applications.
With a DC spark-over voltage of 470V, this device 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 harsh electrical environments.
The component provides low capacitance at 1 MHz, preserving signal integrity in high-speed communication systems, along with high insulation resistance to minimize leakage current. Stable glow voltage and arc voltage characteristics ensure consistent operation and extended service life.
Encased in a compact 2RB-8S package, the 2R470B-8S allows easy integration into various PCB designs. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering dependable surge protection and improved system reliability.
