2R230TB-8 230V Gas Discharge Tube – 2RB-5 Package | RUILON
RUILON
The 2R230TB-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard electronic circuits from transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it ensures fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 230V, this component is optimized for medium-voltage applications, providing a balanced protection threshold that reduces false triggering while maintaining strong surge suppression capability. Compared to lower-voltage GDT variants, it offers improved operational stability under high-energy transient conditions. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs) for reliable protection in surge-prone 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 enhances efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation and long service life.
Encased in a compact 2RB-5 package, the 2R230TB-8 allows easy integration 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.
