The 2R4000T-5 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect sensitive electronic systems from transient overvoltage events such as lightning strikes and switching surges. Featuring a 4000V DC spark-over voltage, this component is optimized for ultra-high-voltage applications requiring excellent insulation strength, stable discharge performance, and long-term durability.
Built with advanced gas discharge technology, the 2R4000T-5 delivers stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion while maintaining strong electrical isolation in high-voltage environments. Its robust capability to withstand high impulse discharge current (8/20µs waveform) ensures efficient surge energy absorption and reliable long-term protection performance.
The compact 2R-5 package supports efficient PCB integration and is suitable for space-constrained designs requiring high-performance surge suppression.
This GDT is widely used in telecommunications equipment, industrial electronics, power systems, signal line protection, and surge protection devices (SPD), delivering consistent and durable circuit protection.
