2R090B-8S 90V Gas Discharge Tube – 2RB-8S Package | RUILON
RUILON
The 2R090B-8S Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Utilizing advanced gas discharge technology, it provides fast response and stable performance, ensuring long-term circuit protection.
With a DC spark-over voltage of 90V, this device is ideal for low-voltage applications requiring precise and timely protection. Compared to lower-voltage variants, it offers improved operational stability while still ensuring early triggering to protect sensitive components. The component supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it suitable for demanding surge environments.
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication lines, along with high insulation resistance to minimize leakage current. Stable glow voltage and arc voltage characteristics contribute to consistent performance and extended service life.
Encased in a compact 2RB-8S package, the 2R090B-8S enables easy integration into various PCB designs. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
