The 2R800LB-8TH is a high-voltage Gas Discharge Tube (GDT) designed for robust surge protection in demanding industrial, telecom, and power system applications. Housed in a compact 2RL-8TH ceramic SMD package, this device provides highly reliable over-voltage protection by safely diverting high-energy transient surges away from sensitive electronic circuitry. Manufactured by RUILON, it ensures long operational life, stable performance, and excellent surge endurance in harsh electrical environments.
This GDT features an 800V DC spark-over voltage (measured at 100V/µs), delivering precise and consistent breakdown behavior under high-voltage stress conditions. It also supports impulse spark-over performance at 1kV/µs, ensuring rapid response to lightning surges, switching transients, and electrical disturbances. With ultra-low capacitance at 1 MHz, it is well-suited for high-speed communication lines, data transmission systems, and sensitive electronic interfaces where signal integrity must be preserved.
The 2R800LB-8TH offers high insulation resistance and optimized discharge characteristics, including stable glow voltage at 10mA and controlled arc voltage at 1A, ensuring efficient energy handling during surge events. Its strong impulse discharge current capability (8/20µs waveform) enhances durability under repeated surge exposure, while its impulse withstand voltage rating ensures long-term protection reliability.
