The 2R1000L-8TH is a high-voltage Gas Discharge Tube (GDT) designed for advanced surge protection in industrial power systems, telecom infrastructure, and high-energy electronic applications. Built in a compact 2RL-8TH ceramic SMD package, this device provides reliable over-voltage protection by safely diverting high-energy transient surges away from sensitive electronic circuits. Manufactured by RUILON, it delivers excellent stability, long service life, and strong surge handling capability under demanding electrical conditions.
This GDT features a 1000V DC spark-over voltage (measured at 100V/µs), ensuring precise and stable breakdown performance under high-voltage surge events. It also supports impulse spark-over capability at 1kV/µs, providing fast response against lightning strikes, switching transients, and severe electrical disturbances. With ultra-low capacitance at 1 MHz, it is highly suitable for high-speed communication lines, signal transmission networks, and sensitive electronic interfaces where signal integrity is critical.
The 2R1000L-8TH offers high insulation resistance and optimized discharge behavior, including stable glow voltage at 10mA and controlled arc voltage at 1A, ensuring efficient energy dissipation during surge events. Its high impulse discharge current capability (8/20µs waveform) enhances durability under repeated surge stress, while its impulse withstand voltage rating ensures long-term reliability in harsh environments.
