The 3R230A-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. With a 230V DC spark-over voltage, this component offers an optimal balance between fast response and stable operation for medium-voltage applications.
Built using advanced gas discharge technology, the 3R230A-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 circuits. Its strong capability to withstand high impulse discharge current (8/20µs waveform) enables efficient surge absorption and long service life.
Compared to lower voltage GDT variants, the 230V model reduces nuisance triggering while maintaining effective surge protection, making it suitable for a wide range of electronic and industrial applications. The compact 3RA-5SS package supports efficient PCB design and reliable performance in space-constrained environments.
This GDT is widely used in telecommunications equipment, power supplies, industrial automation systems, signal line protection, and surge protection devices (SPD), delivering consistent and long-lasting circuit protection.
