2039-xxx-XX Precision, Fast Responding, High Voltage Gas Discharge Tube
Bourns now offers miniature through-hole 2-electrode GDT surge protectors with sparkover voltage up to 1100 V. At only 5 mm in
diameter, the 2039 Series is ideal for board level protection of high bandwidth applications such as xDSL, cable broadband and high
speed Ethernet. The 2039 Series features high energy-handling capability, long and stable life performance and low capacitance of
less than 1 pF.
Bourns® GDTs are designed to prevent damage from transient disturbances within rated limits by acting as a “crowbar” to create a
short-to-ground circuit during conduction. When an electrical surge exceeds the defined breakdown voltage level of the GDT, the
device becomes ionized and rapid conduction takes place. When the surge passes and system voltage returns to normal levels, the
GDT returns to its high-impedance (off) state.
