SMD5542-2000 Gas Discharge Tube (GDT) Surge Protector – 2R-5 Package | RUILON

The SMD5542-2000 Gas Discharge Tube (GDT) from RUILON is a high-reliability surface-mount ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events such as lightning strikes and switching surges. Featuring a 2000V DC spark-over voltage, this component is optimized for high-voltage surge protection applications requiring robust insulation and stable discharge performance.

Built with advanced gas discharge technology, the SMD5542-2000 delivers stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion and strong isolation in high-voltage environments. Its strong capability to withstand high impulse discharge current (8/20µs waveform) ensures reliable energy absorption and long operational life.

Compared to lower voltage variants, the 2000V model provides maximum isolation and enhanced resistance to false triggering in high-voltage systems. The compact SMD5542 surface-mount package supports efficient PCB layout and is ideal for automated assembly and space-constrained designs.

This GDT is widely used in telecommunications equipment, power systems, industrial electronics, signal line protection, and surge protection devices (SPD), delivering consistent and long-lasting circuit protection.
