The 3R200A-5SS Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect electronic circuits from transient overvoltage events such as lightning strikes and switching surges. Featuring a 200V DC spark-over voltage, this component offers a strong balance between fast response and stable operation for low- to medium-voltage applications.
Built with advanced gas discharge technology, the 3R200A-5SS 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 lines. Its capability to withstand high impulse discharge current (8/20µs waveform) ensures efficient surge absorption and long operational life.
Compared to lower voltage GDT variants, the 200V model offers improved resistance to nuisance triggering while maintaining reliable and fast surge suppression performance. The compact 3RA-5SS package supports efficient PCB layout and dependable operation in space-constrained designs.
This GDT is widely used in telecommunications equipment, signal line protection, consumer electronics, industrial automation systems, and surge protection devices (SPD), delivering consistent and long-lasting circuit protection.
