The 3R230A-5S Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to protect electronic systems from transient overvoltage events such as lightning strikes and switching surges. With a 230V DC spark-over voltage, this component offers an ideal balance between sensitivity and stability for medium-voltage applications.
Engineered with advanced gas discharge technology, the 3R230A-5S 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 ability to withstand high impulse discharge current (8/20µs waveform) ensures effective surge absorption and long operational life.
Compared to lower voltage GDT variants, the 230V model reduces the risk of false triggering while maintaining reliable surge protection, making it suitable for a wide range of electronic and industrial applications. The compact 3RA-5S package supports efficient PCB layout and dependable performance in space-constrained designs.
This GDT is widely used in telecommunications equipment, power supplies, industrial automation systems, signal line protection, and surge protection devices (SPD), ensuring consistent and long-lasting circuit protection.
