The 2RL145M-6 (manufactured by Yageo) is a Discharge Tube (GDT/TSS) Surface Mount Device (SMD) that is RoHS compliant. It is a gas-discharge tube (GDT) with two terminal leads that are used to protect electrical circuits from overvoltage transients. The GDT works by providing a path for high-voltage pulses to be safely dissipated. The 2RL145M-6 is a miniature tube with a cylindrical metal body that is coated with a white insulation material. It has an operating voltage range of 6 kV, with a peak current rating of 0.75 kA. The GDT is suitable for use in a wide variety of applications, including telecommunications, power distribution, and data processing.
