The 2R2000L-8TH is a high-voltage Gas Discharge Tube (GDT) engineered for maximum surge protection in heavy-duty industrial, telecom, and high-power electronic systems. Designed in a compact 2RL-8TH ceramic SMD package, this device delivers highly reliable over-voltage protection by safely diverting extreme transient surges away from sensitive circuit components. Manufactured by RUILON, it ensures excellent durability, stable performance, and long service life even under repeated high-energy surge conditions.
This GDT features a 2000V DC spark-over voltage (measured at 100V/µs), providing precise and stable breakdown behavior in high-voltage environments. It also supports impulse spark-over performance at 1kV/µs, ensuring ultra-fast response to lightning strikes, switching transients, and severe electrical disturbances. With ultra-low capacitance at 1 MHz, it is ideal for high-speed communication lines, data transmission systems, and sensitive electronic interfaces where signal integrity must be preserved.
The 2R2000L-8TH offers high insulation resistance and optimized discharge characteristics, including stable glow voltage at 10mA and controlled arc voltage at 1A, ensuring efficient and safe energy dissipation during surge events. Its high impulse discharge current capability (8/20µs waveform) enhances robustness under repeated surge exposure, while its impulse withstand voltage rating ensures long-term reliability in harsh operating conditions.
