The SMD5050-090NA Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection component designed to protect sensitive electronic circuits from lightning strikes, transient overvoltage, and high-energy surge events. With a nominal DC spark-over voltage of 90V (tested at 100V/µs), it ensures fast and accurate triggering, effectively diverting surge currents away from critical components and enhancing system reliability.
Built with advanced ceramic gas discharge technology, the SMD5050-090NA delivers stable impulse spark-over characteristics at 1kV/µs, along with high insulation resistance and low capacitance at 1 MHz. These features make it ideal for high-speed communication lines and precision electronic applications where signal integrity is essential. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage ensure long service life and consistent protection performance under repeated surge conditions.
Compared to higher voltage variants, the 90V model offers faster response sensitivity and improved protection for low-voltage circuits, making it suitable for telecom interfaces, industrial control systems, and consumer electronics. The larger SMD5050 package provides superior thermal dissipation, higher surge current handling capability, and robust mechanical strength, while supporting efficient surface-mount assembly for modern PCB designs.
