2R150TB-8 150V Gas Discharge Tube – 2RB-5 Package | RUILON
RUILON
The 2R150TB-8 Gas Discharge Tube (GDT) from RUILON is a compact, 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 ensures fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 150V, this component is ideal for low to medium voltage applications requiring a balance between sensitivity and operational stability. Compared to lower-voltage GDT variants, it reduces the risk of false triggering while still ensuring effective surge suppression. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs) for reliable protection under surge conditions.
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 2R150TB-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.
