The 3R600A-5S Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to protect electronic systems from high-energy transient overvoltage events such as lightning strikes and switching surges. Featuring a 600V DC spark-over voltage, this component is ideal for high-voltage applications requiring stable and reliable surge protection.
Built with advanced gas discharge technology, the 3R600A-5S ensures stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, minimizing signal distortion in sensitive communication and control circuits. Its strong capability to withstand high impulse discharge current (8/20µs waveform) enables effective surge absorption and extended service life.
Compared to lower voltage GDT variants, the 600V model significantly reduces the risk of false triggering in higher operating voltage environments while maintaining consistent protection performance. The compact 3RA-5S package supports efficient PCB layout and reliable operation in demanding applications.
This GDT is widely used in power supplies, telecommunications equipment, industrial automation systems, signal line protection, and surge protection devices (SPD), delivering dependable and long-lasting circuit protection.
