Notes:

• Surface Mount (SM) parts may show a temporary increase in DCBD after the solder reflow process. Most devices will recover

within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change

in DCBD.

Bourns now offers miniature Surface Mount (SM) 2-electrode GDT surge protectors with sparkover voltage up to 1100 V. Compatible with

“pick and place” assembly systems and 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.

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 system voltage returns to normal levels, the GDT

returns to its high-impedance (off) state.
