3R350B-5S 350V Gas Discharge Tube (GDT) Surge Protector – 3RB-5S Package | RUILON
RUILON
The 3R350B-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. Featuring a 350V DC spark-over voltage, this component is ideal for medium- to high-voltage applications requiring stable and reliable protection.
Engineered with advanced gas discharge technology, the 3R350B-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 strong capability to withstand high impulse discharge current (8/20µs waveform) ensures effective surge absorption and extended service life.
Compared to lower voltage GDT variants, the 350V model offers improved resistance to false triggering while maintaining efficient surge suppression, making it suitable for a wide range of electronic and industrial applications. The compact 3RB-5S package supports efficient PCB layout and reliable operation 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), delivering dependable and long-lasting circuit protection.
