2R090TB-5 90V Gas Discharge Tube – 2RB-5 Package | RUILON

RUILON

The 2R090TB-5 Gas Discharge Tube (GDT) from RUILON is a compact and high-reliability ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it provides fast response and stable long-term protection in demanding applications.

With a DC spark-over voltage of 90V, this device is optimized for low-voltage protection applications requiring precise and early surge clamping. Compared to higher-voltage GDT variants, it ensures quicker triggering to safeguard sensitive components while maintaining stable electrical performance. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), ensuring reliable operation in surge-prone environments.

The component offers low capacitance at 1 MHz, preserving signal integrity in high-speed communication lines, while high insulation resistance minimizes leakage current and improves system efficiency. Stable glow voltage and arc voltage characteristics ensure consistent performance and extended service life.

Encased in a compact 2RB-5 package, the 2R090TB-5 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.
