The 2R3600L-8TH is an ultra-high-voltage Gas Discharge Tube (GDT) engineered for maximum surge protection in heavy-duty industrial, telecom, and power transmission systems. Designed in a compact 2RL-8TH ceramic SMD package, this device provides highly reliable over-voltage protection by safely diverting extreme transient surge energy away from sensitive electronic circuits. Manufactured by RUILON, it delivers excellent durability, stable electrical characteristics, and long service life even under severe surge stress conditions.
This GDT features a 3600V DC spark-over voltage (measured at 100V/µs), ensuring precise and stable breakdown performance in ultra-high-voltage applications. It also supports impulse spark-over capability at 1kV/µs, providing ultra-fast response against lightning strikes, switching surges, and high-energy electrical disturbances. With ultra-low capacitance at 1 MHz, it is suitable for specialized high-voltage signal lines, communication systems, and sensitive interfaces where signal integrity must be preserved.
The 2R3600L-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 robustness under repeated surge exposure, while its impulse withstand voltage rating ensures long-term reliability in extreme electrical environments.
