3 Description

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.
