Additional Details

The ESD5V5U5ULC offers unidirectional ESD protection, meaning it protects against positive ESD strikes on the protected line. Its ultra-low capacitance makes it suitable for protecting high-speed data interfaces without degrading signal quality. The low clamping voltage ensures that the voltage seen by the protected component is limited during an ESD event. The ULC-3-2 package provides a very small footprint, making it ideal for use in portable devices and other space-constrained applications. This device is compliant with the IEC 61000-4-2 standard, which specifies the requirements for ESD immunity testing. Infineon Technologies is a leading manufacturer of semiconductors, renowned for their high-quality and reliable protection devices.
