Bourns offers a low-cost surface mount (SM) 2-electrode GDT surge protection device. The 2055 Series is ideal for broadband protection
due to its ultra-low capacitance. The 2055 Series offers superior protection characteristics suitable for telecommunications, commercial and
industrial applications.

Notes:
• UL Recognized component, UL File E153537.
• At delivery AQL 0.65 Level II, DIN ISO 2859.
• 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 recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D.
