The ESD441W-Q1 is a unidirectional ESD protection diode for protecting data lines and other I/O ports. The ESD441W-Q1 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 1pF (typical) IO capacitance enabling high-speed interfaces protection for protocols such as USB 2.0. The extremely low dynamic resistance (0.16Ω) and clamping voltage (8.2V 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 in portable electronics and other space constrained applications such as wearables.
The ESD441W-Q1 is offered in a wettable flank 0402 package.
