2R470SB-8T25 470V Gas Discharge Tube – 2RS-8T25 Package | RUILON
RUILON
The 2R470SB-8T25 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard 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 demanding electrical environments.
With a DC spark-over voltage of 470V, this component is optimized for medium-to-high voltage surge protection applications, offering an effective balance between protection sensitivity and operational stability. It reduces false triggering while ensuring reliable activation during severe surge conditions. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs) for strong and efficient surge suppression.
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 energy handling capability, and long service life under repeated surge events.
Encased in a compact 2RS-8T25 package, the 2R470SB-8T25 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.
