2R350B-8S 350V Gas Discharge Tube – 2RB-8S Package | RUILON
RUILON
The 2R350B-8S Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to safeguard electronic circuits against high-energy transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it ensures rapid response and reliable long-term protection in demanding environments.
With a DC spark-over voltage of 350V, this device is ideal for medium to high-voltage applications, offering a balanced protection threshold that minimizes false triggering while maintaining strong surge suppression capability. Compared to lower-voltage GDT variants, it provides improved system stability and dependable operation. The component supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs).
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication systems, along with high insulation resistance to reduce leakage current. Stable glow voltage and arc voltage characteristics contribute to consistent performance and extended service life.
Encased in a compact 2RB-8S package, the 2R350B-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 reliable surge protection and enhanced system durability.
