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.
