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 ±30kV
per the IEC 61000-4-2 international standard (greater
than Level 4).
This device features a 0.5pF (typical) IO capacitance
enabling high-speed interface protection for protocols
such as USB 3.0. The extremely low dynamic
resistance (0.19Ω) and clamping voltage (10.4V at
16A TLP) 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 and data lines in portable electronics
and other space constrained applications such as
wearables.
The ESD451 is offered in the industry standard 0201
and 0402 package.
