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 ±30 kV
per the IEC 61000-4-2 international standard (greater
than Level 4).
This device features a 1 pF (typical) IO
capacitance enabling high-speed interfaces protection
for protocols such as USB 2.0. The extremely low
dynamic resistance (0.1 Ω) and clamping voltage (7.6
V at 16 TLP) is specified for system level protection
against transient events.
The 30 kV ESD rating and 6.2 A surge provides
robust transient protection in a tiny package for
protecting 5.5 V power rails in portable electronics
and other space constrained applications such as
wearables.
The ESD441 is offered in the industry standard 0201
(DPL) package.
