Description

The ESD451 is a bidirectional ESD protection diode for protecting data line and other I/O ports. The ESD451 is rated to dissipate ESD strikes up to ±30kV per the IEC 61000-4-2 international standard (greater than Level 4).

This device features a 0.5pF (typical) IO capacitance enabling high-speed interface protection for protocols such as USB 3.0. The extremely low dynamic resistance (0.19Ω) and clamping voltage (10.4V at 16A TLP) is specified for system-level protection against transient events.

The ±30kV ESD rating and 6A surge provides robust transient protection in a tiny package for protecting 5.5V power rails and data lines in portable electronics and other space constrained applications such as wearables.

The ESD451 is offered in the industry standard 0201 and 0402 package.
