2R350TB-8 350V Gas Discharge Tube – 2RB-5 Package | RUILON
RUILON
The 2R350TB-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). Utilizing advanced gas discharge technology, it provides fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 350V, this component is optimized for medium to high-voltage applications, offering a strong balance between protection sensitivity and operational stability. Compared to lower-voltage GDT variants, it reduces false triggering while ensuring effective surge suppression under high-energy transient conditions. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), ensuring reliable protection in harsh 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 improves efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation and extended service life.
Encased in a compact 2RB-5 package, the 2R350TB-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.
