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 high-speed, 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.
