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 4.4 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.
