The 3R800SB-8S Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device engineered to safeguard electronic systems from transient overvoltage events such as lightning strikes and switching surges. Featuring an 800V DC spark-over voltage, this component is designed for high-voltage applications requiring strong and stable surge suppression performance.
Built with advanced gas discharge technology, the 3R800SB-8S provides stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion in communication and control circuits. Its robust design supports high impulse discharge current (8/20µs waveform) for efficient surge energy absorption and long operational life.
Compared to lower voltage variants, the 800V model offers enhanced resistance to false triggering in high-voltage environments while maintaining reliable protection performance. The compact 3RB-8S package enables efficient PCB layout and dependable operation in space-constrained designs.
This GDT is widely used in telecommunications equipment, power systems, industrial automation, signal line protection, and surge protection devices (SPD), delivering consistent and long-lasting circuit protection.
