The 3R800A-5S Gas Discharge Tube (GDT) from RUILON is a high-voltage ceramic surge protection device engineered to protect electronic systems from extreme transient overvoltage events such as lightning strikes and switching surges. Featuring an 800V DC spark-over voltage, this component is ideal for applications requiring high voltage tolerance and enhanced surge protection reliability.
Built with advanced gas discharge technology, the 3R800A-5S delivers stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion in sensitive communication and control circuits. Its robust capability to withstand high impulse discharge current (8/20µs waveform) provides efficient surge absorption and long service life.
Compared to lower voltage GDT variants, the 800V model offers improved resistance to 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 conditions.
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.
