The 2R600LB-8TH is a high-performance Gas Discharge Tube (GDT) engineered for superior surge protection in industrial, telecom, and power electronics applications. Designed 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 ensures excellent durability, stable electrical characteristics, and long service life even under repeated surge stress.
This GDT features a 600V DC spark-over voltage (measured at 100V/µs), offering precise and consistent breakdown behavior under over-voltage conditions. It also supports impulse spark-over performance at 1kV/µs, ensuring fast response against lightning surges, switching transients, and electrical noise disturbances. With ultra-low capacitance at 1 MHz, it is ideal for high-speed signal lines, communication interfaces, and data-sensitive circuits where signal integrity is critical.
The 2R600LB-8TH provides high insulation resistance and optimized discharge performance, 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 conditions, while its impulse withstand voltage rating ensures long-term reliability in harsh electrical environments.
