SMD4532-800NF Gas Discharge Tubes – SMD4532 Package | RUILON

The SMD4532-800NF Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection solution designed to protect electronic systems from lightning strikes, transient overvoltage, and high-energy surge disturbances. With a nominal DC spark-over voltage of 800V (tested at 100V/µs), it provides fast and reliable triggering, effectively diverting surge currents away from sensitive components and ensuring robust system protection.

Engineered with advanced ceramic gas discharge technology, the SMD4532-800NF delivers stable impulse spark-over characteristics at 1kV/µs, along with high insulation resistance and low capacitance at 1 MHz. These properties make it ideal for high-speed communication lines and precision electronics where maintaining signal integrity is critical. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage ensure long service life and consistent performance even under repeated surge exposure.

Compared to lower voltage variants, the 800V model offers maximum voltage tolerance and superior protection margins, making it suitable for demanding industrial applications, telecom infrastructure, and high-power systems. The SMD4532 package provides excellent thermal dissipation, high surge handling capability, and robust mechanical durability, while supporting efficient surface-mount assembly for modern PCB designs.
