The NUP2114UPXV5T1G from onsemi is a high‑performance surge protection device designed to protect high‑speed data lines from electrostatic discharge (ESD) and transient voltage events. With an ultra‑low capacitance of just 0.8pF, this device is ideally suited for high‑speed communication interfaces such as USB 2.0, Gigabit Ethernet, HDMI, and DVI, where signal integrity is critical. It offers excellent ESD protection, exceeding IEC 61000‑4‑2 Level 4 requirements, with human body model (HBM) ratings of Class 3B (>8kV) and machine model (MM) ratings of Class C (>400V). The NUP2114 features low clamping voltage and low leakage current, ensuring robust protection without compromising system performance. The device is available in a compact SOT‑553 surface‑mount package, is Pb‑free, halogen‑free, BFR‑free, and RoHS compliant. The S‑prefix version is AEC‑Q101 qualified and PPAP capable, making it suitable for automotive and other applications requiring stringent site and process control.
