2R2500L-8TH 2500V Gas Discharge Tube (GDT) Surge Protector – 2RL-8TH Package | RUILON
RUILON
The 2R2500L-8TH is a high-voltage Gas Discharge Tube (GDT) engineered for maximum surge protection in industrial, telecom, and high-power electronic 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 performance, and long service life even under harsh surge conditions.
This GDT features a 2500V DC spark-over voltage (measured at 100V/µs), ensuring precise and consistent breakdown performance in high-voltage environments. It also supports impulse spark-over capability at 1kV/µs, enabling ultra-fast response against lightning strikes, switching surges, and severe electrical transients. With ultra-low capacitance at 1 MHz, it is ideal for high-speed communication lines, data transmission networks, and sensitive signal interfaces where maintaining signal integrity is critical.
The 2R2500L-8TH offers high insulation resistance and optimized discharge characteristics, 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 stress, while its impulse withstand voltage rating ensures long-term reliability in demanding operating conditions.
