2R090TD-8 90V Gas Discharge Tube – 2RD-8 Package | RUILON
RUILON
The 2R090TD-8 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). Using advanced gas discharge technology, it provides ultra-fast response and stable long-term protection in harsh electrical environments.
With a DC spark-over voltage of 90V, this component is optimized for low-voltage protection applications requiring precise and early surge triggering. Compared to higher-voltage GDT variants, it ensures faster activation to protect sensitive components while maintaining stable operation under normal working conditions. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs) for reliable 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 efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation, strong energy handling, and long service life.
Encased in a compact 2RD-8 package, the 2R090TD-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.
