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
high energy-handling capability, long
voltages are nearly equal line to line
transient disturbances by acting as a

Notes:
• 2038-35 UL Recognized , file E153537, 2038-110 CSA Approved , file 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 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.
• Sparkover limits after life ±30 %. IR >10⁸ Ω.
• Operating characteristics per RUS PE-80 and Telcordia GR 1361 available on request.
• At delivery AQL 0.65 Level II, DIN ISO 2859.
• Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D.
