3 Description

The ESD451 is a bidirectional ESD protection diode

for protecting data line and other I/O ports. The

ESD451 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 0.5 pF (typical) IO capacitance

enabling high-speed interface protection for protocols

such as USB 3.0. The extremely low dynamic

resistance (0.19 Ω) and clamping voltage (10.4 V

at 16 A 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 and data lines in portable

electronics and other space constrained applications

such as wearables.

The ESD451 is offered in the industry standard 0201

(DPL) package.
