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.
