The AQ2555NUTG is a low-capacitance, TVS Diode Array designed to provide protection against ESD (electrostatic discharge), CDE (cable discharge events), EFT (electrical
fast transients), and lightning induced surges for highspeed, differential data lines. It’s packaged in a μDFN package (3.0 x 2.0mm) and each component can protect up 4 channels or 2 differential pairs, up to 45A (IEC 61000- 4- 5 2nd edition,) and up to 30kV ESD (IEC 61000-4-2). The “flow-through” design minimizes signal distortion, reduces
voltage overshoot, and provides a simplified PCB design. The AQ2555NUTG with its low capacitance and low clamping voltage makes it ideal for high-speed data interfaces such as 1GbE applications found in notebooks, switches, etc.

Features:

  • ESD, IEC 61000-4-2, ±30kV contact, ±30kV air
  • EFT, IEC 61000-4-4, 50A (5/50ns)
  • Lightning, IEC 61000-4-5 2nd edition, 45A (tP=8/20μs)
  • Low capacitance of 2.5pF@0V (TYP) per I/O
  • Low leakage current of 0.1μA (TYP) at 2.5V
  • μDFN-10 package is optimized for high-speed data line routing
  • Provides protection for two differential data pairs (4 channels) up to 45A
  • Low operating and clamping voltage
  • AEC-Q101 qualified
  • Halogen free, Lead free and RoHS compliant
  • Moisture Sensitivity Level (MSL -1)

Applications:

  • Applications:
  • 10/100/1000 Ethernet
  • WAN/LAN Equipment
  • Desktops, Servers and Notebooks
  • LVDS Interfaces
  • Integrated Magnetics
