SMD4532-150NF Gas Discharge Tubes – SMD4532 Package | RUILON

The SMD4532-150NF Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection component designed to safeguard electronic circuits from lightning strikes, transient overvoltage, and high-energy surge disturbances. With a nominal DC spark-over voltage of 150V (tested at 100V/µs), it ensures fast and reliable activation, effectively diverting surge currents away from sensitive components and maintaining system integrity.

Built using advanced ceramic gas discharge technology, the SMD4532-150NF provides stable impulse spark-over characteristics at 1kV/µs, along with high insulation resistance and low capacitance at 1 MHz. This makes it highly suitable for high-speed communication lines and precision electronic applications where signal integrity must be preserved. Its strong impulse discharge current capability (8/20µs waveform) and high impulse withstanding voltage ensure consistent performance and long operational life even under repeated surge conditions.

Compared to lower voltage models, the 150V variant offers higher voltage tolerance and improved protection margins, making it ideal for industrial systems and power-related applications requiring enhanced surge protection. The SMD4532 package delivers superior thermal performance, higher surge handling capability, and robust mechanical strength, while supporting efficient surface-mount assembly for modern PCB designs.
