2039-xxx-SM Precision, Fast Responding, High Voltage Gas Discharge Tube
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.
Bourns ? GDTs are designed to prevent damage from transient disturbances by acting as a “crowbar” to create a short-to-ground circuit
during conduction. When an electrical surge exceeds the de?ned 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.

Notes:
? Surface Mount (SM) parts may show a temporary increase in DCBD after the solder re?ow 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.
? Sparkover limits after life +30/-25 %, IR >10 8 Ω .
? At delivery AQL 0.65 Level II, DIN ISO 2859.
