2038 Series Miniature Symmetrical 3-Electrode Surface Mount Gas Discharge Tube
Bourns offers a symmetrical surface mount (SM) 3-electrode GDT surge protection device. The industry-leading quality and features of the
Bourns ? miniature-TRIGARD TM series GDT continue in the 2038 symmetrical version. The 2038 series is ideal for board level protection of
high bandwidth applications such as xDSL, cable broadband and high speed Ethernet, due to its symmetrical turn on 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. Bourns ? Gas Discharge Tubes (GDT) are designed to 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 de?ned breakdown voltage level of the GDT, the gas becomes ionized and rapid conduction takes place. When the surge passes
and the system voltage returns to normal levels, the GDT returns to its high-impedance (off) state.

Notes:
? 2038-35 UL Recognized , ?le E153537, 2038-110 CSA Approved , ?le LR93265 (UL 1449).
? The rated discharge current for Mini-TRIGARD? GDTs is the total current equally divided between each line to ground.
? 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 %. IR >10 8 Ω .
? Operating characteristics per RUS PE-80 and Telcordia GR 1361 available on request.
? At delivery AQL 0.65 Level II, DIN ISO 2859.
1 Line to Line DC Sparkover tolerance typically less than +30 % at 100 V/s.
2 Network applied.
3 DC Sparkover may exceed ±30 % but will continue to protect without venting.
