3 Description

The ESD851 is a bidirectional ESD protection

diode designed for clamping harmful transients

such as ESD and surge. The ESD851 is rated to

dissipate ESD strikes up to ±30kV (contact and air

gap discharge), which exceeds the maximum level

specified in the IEC 61000-4-2 international standard

(Level 4). For surges, the device can clamp 8/20μs

surges with peak currents up to 6.5A in accordance

with the IEC 61000-4-5 standard.

This device also features a 4.3pF (typical) IO

capacitance enabling it to protect data lines. The

low dynamic resistance and low clamping voltage

provides system level protection against transient

events.

The ESD851 is offered in the industry standard,

leaded SOD-323 package to enable easy

solderability.
