This is a Gas Discharge Tube (GDT) or Gas Plasma Arrestor designed for voltage protection applications. It operates within a voltage range of 184V to 276V and a maximum current of 5A. The device features a surface mount design with two electrodes and terminals, measuring approximately 6.2mm in depth and height, and 4.1mm in length. It supports an operating temperature range from -40°C to 90°C and is packaged in tape and reel for easy assembly. Key specifications include a maximum capacitance of 1.2pF at 1MHz, a maximum DC holdover voltage of 135V at 150ms, and typical DC sparkover voltage of 230V at 100V/s. It is suitable for high-voltage pulse discharge applications, with impulse discharge current of 10A and impulse sparkover voltages up to 700V under various testing conditions.
