SMD4532-230NF Gas Discharge Tubes – SMD4532 Package | RUILON

The SMD4532-230NF Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device designed to protect sensitive electronic systems from lightning strikes, transient overvoltage, and high-energy surge events. With a nominal DC spark-over voltage of 230V (tested at 100V/µs), it provides fast and reliable activation, efficiently diverting surge currents away from critical components and ensuring system stability.

Manufactured using advanced ceramic gas discharge technology, the SMD4532-230NF offers stable impulse spark-over characteristics 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 circuits where signal integrity is crucial. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage ensure long service life and dependable performance even under repeated surge conditions.

Compared to lower voltage variants, the 230V model provides higher voltage tolerance and enhanced protection margins, making it ideal for industrial systems, power supplies, and telecom infrastructure. The SMD4532 package ensures superior thermal performance, higher surge handling capability, and robust mechanical durability, while supporting efficient surface-mount assembly for modern PCB designs.
