The 2R3000L-8TH is an ultra-high-voltage Gas Discharge Tube (GDT) designed for maximum surge protection in demanding industrial, telecom, and high-power electronic systems. Housed 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 ensures excellent durability, stable electrical characteristics, and long service life even under repeated high-energy surge conditions.
This GDT features a 3000V DC spark-over voltage (measured at 100V/µs), delivering precise and consistent breakdown performance in ultra-high-voltage environments. It also supports impulse spark-over capability at 1kV/µs, ensuring ultra-fast response against lightning strikes, switching surges, and severe electrical disturbances. With ultra-low capacitance at 1 MHz, it is well-suited for high-speed communication lines, data transmission systems, and sensitive signal interfaces where maintaining signal integrity is critical.
The 2R3000L-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 durability under repeated surge stress, while its impulse withstand voltage rating ensures long-term reliability in harsh operating conditions.
