SMD3216-150N Gas Discharge Tubes – SMD3216 Package | RUILON

The SMD3216-150N Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection component designed to protect sensitive electronic systems from lightning strikes, transient overvoltage, and switching surges. With a nominal DC spark-over voltage of 150V (tested at 100V/µs), it provides precise and fast response, ensuring effective diversion of high-energy transients away from critical circuitry.

Built using advanced ceramic gas discharge technology, the SMD3216-150N offers 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 protection with minimal signal interference. It also features strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage capacity, ensuring long service life and consistent protection under repeated surge conditions.

Compared to lower voltage GDT series, the 150V variant provides a higher operating voltage margin, making it suitable for applications requiring greater tolerance without compromising protection efficiency. The compact SMD3216 package supports flexible PCB layouts and automated assembly, making it ideal for space-constrained and high-density designs.
