The SP2555NUTG 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 device 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 SP2555NUTG 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.
