The Yageo 3RL150M-5-S with Discharge Tube (GDT/TSS) is a RoHS-compliant device designed to protect a high-voltage circuit from over-current. It is composed of two terminals – the primary (p) and the secondary (s). The primary (p) terminal is connected directly to a high voltage circuit, and the secondary (s) terminal is connected to ground. The primary (p) terminal is equipped with the GDT/TSS discharge tube, which provides overcurrent protection by regulating the current through the tube and providing a spark gap. The secondary (s) terminal is equipped with the current limiting resistor which limits the excess current. The device has a maximum voltage rating of 150VDC, and a maximum current rating of 5A. Additionally, it features a 30mOhm impedance and a fast response time. This electronic part is designed for high voltage applications, and can be used in a wide range of applications, including power conversion, electric motors, and high voltage switch applications.
