2R090TD-8T2 90V Gas Discharge Tube – 2RT-8T2 Package | RUILON
RUILON
The 2R090TD-8T2 Gas Discharge Tube (GDT) from RUILON is a 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). Using advanced gas discharge technology, it delivers 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 provides fast activation to safeguard 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 2RT-8T2 package, the 2R090TD-8T2 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.
