2R090D-8S 90V Gas Discharge Tube – 2RD-8S Package | RUILON
RUILON
The 2R090D-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 ensures fast response and stable performance, delivering consistent protection in demanding applications.
With a DC spark-over voltage of 90V, this component is ideal for low-voltage applications requiring accurate and timely protection. Compared to lower-voltage variants, it offers improved operational stability while still ensuring early triggering to safeguard sensitive components. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it suitable for surge-prone environments.
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication systems, while high insulation resistance minimizes leakage current and enhances efficiency. Stable glow voltage and arc voltage characteristics ensure reliable operation and extended service life.
Encased in a compact 2RD-8S package, the 2R090D-8S allows easy integration into various PCB layouts. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering dependable surge protection and improved system reliability.
