2035-xx-SM Precision Gas Discharge Tube Surge Protector
Bourns now offers a surface mount (SM) 2-electrode GDT surge protection device. The industry-leading quality and features of the
Bourns
®
miniature 2035 Series GDT continue in this new SM version. Compatible with “pick and place” assembly systems, the SM is
ideal for high-density applications such as PCBs for telecommunications, commercial and industrial applications.

Notes:
• UL Recognized component, UL File E153537
• 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 ±20 % (-25 %, +30 % for Model 2035-09, 2035-60), IR >10

.
• At delivery AQL 0.65 Level II, DIN ISO 2859.
• Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D.
