The SMD4532-200NF Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection solution designed to protect electronic circuits from lightning strikes, transient overvoltage, and high-energy surge events. With a nominal DC spark-over voltage of 200V (tested at 100V/µs), it ensures fast and stable triggering, effectively diverting surge currents away from sensitive components and enhancing overall system durability.
Utilizing advanced ceramic gas discharge technology, the SMD4532-200NF provides consistent impulse spark-over performance 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 maintaining signal integrity is essential. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage ensure long service life and reliable operation under repeated surge exposure.
Compared to lower voltage variants, the 200V model offers increased voltage tolerance and improved protection margins, making it suitable for industrial equipment, power systems, and communication infrastructure. The SMD4532 package enhances thermal dissipation, supports higher surge current handling, and provides robust mechanical stability, while enabling efficient surface-mount assembly for modern PCB designs.
