The 2RL090M-5-SST4.2 with Discharge Tubes (GDT/TSS) SMD RoHS manufactured by Yageo is a surface-mount surge arrestor with discharge tubes that provide precision and low attenuation protection in high-frequency and high-energy interruption applications. It offers overvoltage protection from high pulse energy discharges and quick turn-on time in high energy applications. This component is RoHS compliant, meaning it is free of hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. The device features an extended temperature range between -55°C and 125°C, low-temperature coefficient, fast steady-state response, multiple Pico-second event detection with minimal voltage drop and optimal response time. It is suitable for applications such as Gigabit Ethernet ports, set top boxes, and other high-speed digital networks.
