2R1000-8S 1000V Gas Discharge Tube – 2RB-8S Package | RUILON
RUILON
The 2R1000-8S Gas Discharge Tube (GDT) from RUILON is a high-voltage ceramic surge protection device designed to protect electronic circuits from extreme transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Utilizing advanced gas discharge technology, it ensures ultra-fast response and reliable long-term protection in harsh environments.
With a DC spark-over voltage of 1000V, this component is ideal for high-voltage and heavy-duty applications where maximum surge tolerance and operational stability are required. Compared to lower-voltage GDT variants, it significantly reduces the risk of false triggering while maintaining strong surge suppression capability. The device supports high impulse discharge current (8/20µs) and offers excellent impulse spark-over performance (1kV/µs), making it suitable for high-energy environments.
The device features low capacitance at 1 MHz, preserving signal integrity in sensitive communication lines, 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 2RB-8S package, the 2R1000-8S allows easy integration into various PCB layouts. It is widely used in telecommunications infrastructure, industrial systems, power equipment, smart grid applications, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
