The 2RL400L-5 with Discharge Tubes (GDT/TSS) RoHS manufactured by Yageo is a two-stage overvoltage Protector. It is a multi-layer disc-shaped hybrid device consisting of two Gas-Discharge Tubes assembled on two High-Voltage PTC Elements, making it suitable for a wide range of applications. The two TSS Discharge Tubes ensure a very fast reaction time to transients, providing reliable and effective protection from lightning or power surges in electrical systems. The device features RoHS compliant parts, making it safe for use in a variety of applications. It offers excellent resistance to ringing and false triggering, and provides a high temperature range (-40 to +90 °C) and a longer shelf life, with an ultra-low profile for space-saving installations. The device also features a wide operating range, low capacitance, and long operating time.
