2R090TA-5 90V Gas Discharge Tube – 2RA-5 Package | RUILON
RUILON
The 2R090TA-5 Gas Discharge Tube (GDT) from RUILON is a compact and 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 long-term protection in demanding applications.
With a DC spark-over voltage of 90V, this component 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 safeguard sensitive components. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs), ensuring reliable protection in 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 consistent operation and extended service life.
Encased in a compact 2RA-5 package, the 2R090TA-5 allows easy integration into space-constrained PCB designs. 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.
