PUSB2X4YH is a high-speed, dual-channel ESD Suppressor manufactured by Nexperia (formerly NXP Semiconductors) for applications such as USB, MIPI, eMMC, LLI, DSI, and CSI. It works by suppressing transient voltages to ensure that electronic devices are protected from electrostatic discharge (ESD). It provides a safe, integrated solution to the common problem of ESD damage occurring when two conductors come into contact at very high speeds, with excellent thermal performance and low insertion and clamping losses. Its integrated circuitry is capable of tolerating high-voltage transients, while dissipating energy to limit the peak current threat. The ESD protection for high-speed interface also provides unidirectional ESD protection to ensure safe data transfer on both data (D) and ground (G) lines. Its advanced design allows for a wide operating temperature range, making it suitable for use in various applications or products, including automotive networks.
