The 2R090SB-8T25 Gas Discharge Tube (GDT) from RUILON is a compact and highly reliable ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events. With a 90V DC spark-over voltage, this component is ideal for low-voltage applications requiring fast and precise protection.
Built using advanced gas discharge technology, the 2R090SB-8T25 offers stable impulse spark-over performance at 1KV/µs, high insulation resistance, and low capacitance at 1 MHz, ensuring minimal signal interference in high-speed communication and data lines. Its ability to handle high impulse discharge current (8/20µs waveform) provides excellent surge protection and long service life.
Compared to higher voltage GDT variants, the 90V model enables earlier clamping of transient surges, making it especially suitable for protecting low-voltage circuits and sensitive components. The 2RS-8T25 package ensures compact size and reliable performance, supporting efficient PCB design and space-saving layouts.
This GDT is widely used in telecommunication equipment, signal line protection, consumer electronics, industrial control systems, and surge protection modules, delivering dependable and efficient circuit protection.
