The 3R600A-5S is a high-performance Gas Discharge Tube (GDT) designed for reliable surge protection in industrial, telecom, and advanced electronic systems. Built in a compact 3RA-5S ceramic SMD package, this device provides efficient over-voltage protection by safely diverting high-energy transient surges away from sensitive electronic components. Manufactured by RUILON, it ensures stable operation, long service life, and strong surge endurance even under repeated electrical stress conditions.
This GDT features a 600V DC spark-over voltage (measured at 100V/µs), offering precise and consistent breakdown behavior for high-voltage protection applications. It also supports impulse spark-over capability at 1kV/µs, ensuring fast response against lightning surges, switching transients, and electrostatic discharge events. With ultra-low capacitance at 1 MHz, it is highly suitable for high-speed communication lines, data transmission systems, and signal-sensitive circuits where maintaining signal integrity is critical.
The 3R600A-5S 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 durability under repetitive surge stress, while its impulse withstand voltage rating ensures long-term reliability in harsh operating environments.
