The SMD3225-150N Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection device engineered to protect sensitive electronic circuits from lightning-induced surges, transient overvoltage, and high-energy electrical disturbances. With a nominal DC spark-over voltage of 150V (tested at 100V/µs), it ensures fast and precise response, effectively diverting surge currents away from critical components and improving system safety.
Built with advanced ceramic gas discharge technology, the SMD3225-150N provides stable impulse spark-over performance (1kV/µs), high insulation resistance, and low capacitance at 1 MHz, making it ideal for high-speed communication and signal line applications where signal integrity is essential. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstand voltage ensure long-term durability and consistent protection even under repeated surge events.
Compared to lower voltage variants, the 150V model offers a higher operating voltage margin while maintaining fast response and strong surge handling capability, making it suitable for industrial and communication systems requiring balanced protection performance. The SMD3225 package delivers enhanced thermal dissipation, mechanical robustness, and compatibility with automated surface-mount assembly, making it ideal for modern compact PCB designs.
