The 2R350LB-8TH is a high-reliability Gas Discharge Tube (GDT) designed for advanced surge protection in compact electronic systems. Built in a space-saving 2RL-8TH ceramic SMD package, this device effectively protects sensitive circuits by diverting high-energy transient surges safely to ground. Manufactured by RUILON, it delivers stable electrical performance, long service life, and strong surge endurance for demanding applications.
This GDT features a 350V DC spark-over voltage (measured at 100V/µs), ensuring accurate and consistent triggering under over-voltage conditions. It also supports impulse spark-over performance at 1kV/µs, providing fast response against lightning surges, switching transients, and power disturbances. With ultra-low capacitance at 1 MHz, it is highly suitable for high-speed signal lines, telecom interfaces, and data communication circuits where signal integrity is critical.
The 2R350LB-8TH offers excellent 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 the impulse withstand voltage rating ensures long-term reliability in harsh electrical environments.
