Specifi cations are subject to change without notice.
The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.
Users should verify actual device performance in their specifi c applications.
Bourns offers a low-cost, 3-electrode surface mount GDT surge protection device. The 2054 Series is ideal for broadband
protection due to its ultra-low capacitance. The 2054 Series offers superior protection characteristics suitable for telecommunications,
commercial and industrial applications.

Notes:
• UL Recognized component, UL File E153537.
• Line to Line voltage is approximately 1.8 to 2 times the stated Line to Ground voltage.
• The rated discharge current 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 refl 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.
• At delivery AQL 0.65 AQL Level II, DIN ISO 2859
• Bourns recommends refl owing surface mount devices per IPC/JEDEC J-STD-020 rev D.
