2R300TB-8 300V Gas Discharge Tube – 2RB-5 Package | RUILON
RUILON
The 2R300TB-8 Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to protect electronic circuits from transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it delivers fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 300V, this component is ideal for medium-voltage applications requiring a balanced protection threshold. It offers improved stability compared to lower-voltage GDT variants, reducing false triggering while ensuring effective surge suppression under high-energy transient conditions. The device supports high impulse discharge current (8/20µs) and provides excellent impulse spark-over performance (1kV/µs) for reliable protection.
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 efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation and long service life.
Encased in a compact 2RB-5 package, the 2R300TB-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.
