SMD4532-500NF Gas Discharge Tubes – SMD4532 Package | RUILON
RUILON
The SMD4532-500NF Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device designed to protect electronic systems from lightning strikes, transient overvoltage, and high-energy electrical disturbances. With a nominal DC spark-over voltage of 500V (tested at 100V/µs), it delivers fast and reliable triggering, efficiently diverting surge currents away from sensitive components and ensuring long-term system stability.
Engineered using advanced ceramic gas discharge technology, the SMD4532-500NF provides stable impulse spark-over performance at 1kV/µs, along with high insulation resistance and low capacitance at 1 MHz. These features make it highly suitable for high-speed communication lines and precision electronic applications where signal integrity is critical. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage ensure consistent protection performance and extended service life even under repeated surge exposure.
Compared to lower voltage variants, the 500V model offers significantly higher voltage tolerance and improved protection margins, making it ideal for industrial equipment, telecom infrastructure, and power supply systems. The SMD4532 package enhances thermal dissipation, supports higher surge current handling, and provides robust mechanical strength, while enabling efficient surface-mount assembly for modern PCB designs.
