SMD4532-090NF Gas Discharge Tubes – SMD4532 Package | RUILON

The SMD4532-090NF Gas Discharge Tube (GDT) from RUILON is a robust and high-reliability surge protection component designed to safeguard electronic circuits against lightning strikes, transient overvoltage, and high-energy surge events. With a nominal DC spark-over voltage of 90V (tested at 100V/µs), it ensures fast triggering and efficient diversion of surge currents, protecting sensitive downstream components.

Engineered with advanced ceramic gas discharge technology, the SMD4532-090NF delivers stable impulse spark-over characteristics at 1kV/µs, along with high insulation resistance and ultra-low capacitance at 1 MHz. This makes it highly suitable for high-speed communication lines and precision electronic systems where maintaining signal integrity is critical. Its strong impulse discharge current capability (8/20µs waveform) and high impulse withstanding voltage ensure consistent performance and long operational life even under repeated surge exposure.

Compared to lower voltage models, the 90V variant provides a higher protection threshold, making it ideal for applications requiring improved voltage tolerance without compromising response time. The SMD4532 package enhances thermal dissipation, supports higher surge handling capacity, and ensures mechanical durability, while enabling seamless integration into automated surface-mount manufacturing processes.
