SMD3216-200N Gas Discharge Tubes – SMD3216 Package | RUILON

The SMD3216-200N Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device 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 provides fast and reliable activation, ensuring effective diversion of surge currents and safeguarding sensitive components.

Utilizing advanced ceramic gas discharge technology, the SMD3216-200N delivers stable impulse spark-over performance (1kV/µs), high insulation resistance, and low capacitance at 1 MHz, making it ideal for high-frequency signal lines and communication interfaces with minimal signal distortion. Its strong impulse discharge current capability (8/20µs waveform) and high impulse withstanding voltage ensure durability and long-term reliability, even under repeated surge conditions.

Compared to lower voltage GDT series, the 200V variant offers a higher operating voltage margin and improved system stability, making it suitable for applications with elevated voltage requirements while maintaining efficient surge protection. The compact SMD3216 package enables flexible PCB layout and supports automated surface-mount assembly, making it ideal for modern compact electronic designs.
