The SMD3225-600N Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection device engineered to protect sensitive electronic systems from lightning strikes, transient overvoltage, and high-energy electrical disturbances. With a nominal DC spark-over voltage of 600V (tested at 100V/µs), it provides fast and reliable triggering, ensuring effective diversion of surge currents and safeguarding critical components in demanding environments.
Built using advanced ceramic gas discharge technology, the SMD3225-600N offers stable impulse spark-over performance (1kV/µs), high insulation resistance, and ultra-low capacitance at 1 MHz, making it ideal for high-speed communication lines and signal-sensitive applications. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstand voltage ensure long service life and consistent protection even under repeated surge stress.
Compared to lower voltage variants, the 600V model provides significantly higher operating voltage margin and enhanced system robustness, making it suitable for industrial power systems, telecom infrastructure, and high-voltage applications. The SMD3225 package delivers excellent thermal dissipation, mechanical durability, and compatibility with automated surface-mount assembly, ensuring flexible integration into modern PCB designs.
