SMD4532-1000NF Gas Discharge Tubes – SMD4532 Package | RUILON

RUILON

The SMD4532-1000NF Gas Discharge Tube (GDT) from RUILON is a premium high-voltage surge protection device engineered to safeguard electronic systems from lightning strikes, transient overvoltage, and extreme surge events. With a nominal DC spark-over voltage of 1000V (tested at 100V/µs), it ensures rapid and reliable activation, efficiently diverting high-energy surge currents away from sensitive circuitry and maintaining system integrity.

Developed using advanced ceramic gas discharge technology, the SMD4532-1000NF provides stable impulse spark-over performance at 1kV/µs, along with high insulation resistance and low capacitance at 1 MHz. These characteristics make it ideal for high-speed communication lines and precision electronic applications where signal integrity is critical. Its strong impulse discharge current capability (8/20µs waveform) and superior impulse withstanding voltage ensure long service life and dependable performance even under repeated surge conditions.

Compared to lower voltage variants, the 1000V model delivers maximum voltage tolerance and the highest protection margin within the series, making it ideal for demanding industrial systems, telecom infrastructure, and high-power applications. The SMD4532 package enhances thermal performance, supports high surge handling capability, and ensures robust mechanical durability, while enabling efficient surface-mount assembly for modern PCB designs.
