characteristics as well as high energy-handling capability, long and stable life performance and low capacitance of less than 1 pF . The 2038 series’ breakdown voltages are nearly equal line to line as well as line to ground. Typical 3-electrode GDT line-line breakdown voltages are 1.8-2 times higher than the line to ground breakdown voltage. Bourns ?Gas Discharge Tubes (GDT) prevent damage from transient disturbances by acting as a “crowbar” in creating a virtual short-to-ground circuit during conduction. When an electrical surge exceeds the defined breakdown voltage level of the GDT, the device becomes ionized and conduction takes place within a fraction of a microsecond. When the surge passes and the system voltage returns to normal levels, the GDT returns to its high-impedance (off) state.
