The SMD4532-1500NF Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection device designed to provide superior protection against lightning strikes, transient overvoltage, and extreme surge events in demanding electronic applications. With a nominal DC spark-over voltage of 1500V (tested at 100V/µs), it ensures fast and dependable activation, effectively diverting high-energy surge currents away from sensitive components and maintaining system stability.
Built using advanced ceramic gas discharge technology, the SMD4532-1500NF offers 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 circuits where signal integrity must be preserved. Its strong impulse discharge current capability (8/20µs waveform) and excellent impulse withstanding voltage ensure long service life and reliable protection even under repeated surge exposure.
Compared to lower voltage variants, the 1500V model provides significantly higher voltage tolerance and maximum protection margin, making it ideal for high-voltage industrial systems, telecom infrastructure, and power distribution applications. The SMD4532 package enhances thermal dissipation, supports high surge handling capability, and ensures robust mechanical durability, while enabling efficient surface-mount assembly for modern PCB designs.
