2R090LB-8TH 90V Gas Discharge Tube – 2RL-8TH Package | RUILON
RUILON
The 2R090LB-8TH Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard sensitive electronic circuits from transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Utilizing advanced gas discharge technology, it provides ultra-fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 90V, this component is optimized for low-voltage surge protection applications requiring precise and early triggering. It ensures fast activation to protect sensitive downstream components while maintaining stable performance under normal operating conditions. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs) for effective surge suppression.
The device features low capacitance at 1 MHz, helping preserve signal integrity in high-speed communication systems, while high insulation resistance reduces leakage current and improves overall efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation, strong energy handling capability, and long service life.
Encased in a compact 2RL-8TH package, the 2R090LB-8TH allows easy integration into PCB designs with space constraints. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering reliable surge protection and enhanced system durability.
