RUILON 2R150TA-5

Gas discharge tubes (GDTs) are generally in a high insulation resistance state, equivalent to an open circuit, which has almost no impact on the normal operation of the circuit. When transient overvoltage occurs in the circuit and the voltage amplitude exceeds the breakdown voltage of the GDT, the gas inside the GDT is ionized, causing the GDT to quickly conduct and limit the overvoltage to a lower level, thereby protecting electronic devices or circuit components connected in parallel from high voltage impact damage. After the overvoltage disappears, the GDT immediately returns to a high insulation resistance state, and the circuit resumes normal operation.

The 2RA - 5 series GDT is a device that offers axial leads or surface mount packaging. It is not only small in size and easy to install on various compact printed circuit boards (PCBs), but also has excellent performance. When used in high - frequency communication circuits, the low capacitance characteristic minimizes its impact on the signal. High insulation resistance ensures that the performance of the circuit will not suffer additional losses under normal operating conditions. The 2RA - 5 series GDT can not only be used to protect communication interfaces, but its ability to withstand high surge currents (8/20uS, 5KA) also makes it suitable for power protection.
