Space-saving industry standard 0201 footprint (0.6mm × 0.3mm) and 0402 footprint (1.0mm x 0.6mm)
The ESD441 is a unidirectional ESD protection diode for protecting data lines and other I/O ports. The ESD441 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 (0.1Ω) and clamping voltage (7.6V at 16TLP) 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 ESD441 is offered in the industry standard 0201 and 0402 package.
