The 2R1500T-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect electronic circuits from transient overvoltage events such as lightning strikes and switching surges. Featuring a 1500V DC spark-over voltage, this component is optimized for high-voltage applications requiring stable discharge behavior, strong insulation performance, and long-term durability.
Built with advanced gas discharge technology, the 2R1500T-8 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 excellent electrical isolation in high-voltage environments. Its strong capability to withstand high impulse discharge current (8/20µs waveform) ensures efficient surge energy absorption and reliable long-term protection.
The compact 2R-8 package supports efficient PCB integration and is ideal for space-constrained designs requiring robust surge suppression performance.
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.
