The SMD3216-090N Gas Discharge Tube (GDT) from RUILON is a compact and highly reliable surge protection device designed to protect sensitive electronic circuits from lightning strikes, transient overvoltage, and electrostatic discharge. With a nominal DC spark-over voltage of 90V (tested at 100V/µs), it ensures fast and precise response, effectively diverting high-energy surges away from critical components.
Manufactured using advanced ceramic gas discharge technology, the SMD3216-090N delivers stable impulse spark-over characteristics (1kV/µs), high insulation resistance, and low capacitance at 1 MHz, making it ideal for high-speed communication and signal lines with minimal signal distortion. It also features strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage performance, ensuring durability and long service life even under repeated surge conditions.
Compared to lower voltage GDT series, the 90V configuration provides improved system voltage tolerance and enhanced protection margin, making it suitable for applications requiring higher operating voltages without compromising response efficiency. The compact SMD3216 package supports flexible PCB layout and automated surface-mount assembly, making it ideal for modern, space-constrained designs.
