2R1500L-8TH 1500V Gas Discharge Tube (GDT) Surge Protector – 2RL-8TH Package | RUILON

The 2R1500L-8TH is a high-voltage Gas Discharge Tube (GDT) designed for superior surge protection in demanding industrial, telecom, and high-power electronic applications. Housed in a compact 2RL-8TH ceramic SMD package, this device provides robust over-voltage protection by safely diverting high-energy transient surges away from sensitive circuitry. Manufactured by RUILON, it ensures high reliability, long service life, and stable performance even under repeated surge stress conditions.

This GDT features a 1500V DC spark-over voltage (measured at 100V/µs), delivering precise and consistent breakdown behavior for high-voltage protection scenarios. It also supports impulse spark-over performance at 1kV/µs, ensuring fast and reliable response against lightning strikes, switching surges, and severe electrical transients. 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 maintained.

The 2R1500L-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 strong impulse discharge current capability (8/20µs waveform) enhances durability under repetitive surge exposure, while the impulse withstand voltage rating ensures long-term operational stability in harsh environments.
