3 Description

The ESD851-Q1 is a bidirectional ESD protection

diode designed for clamping harmful transients such

as ESD and surge. The ESD851-Q1 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-Q1 is offered in the industry

standard, leaded SOD-323 package to enable easy

solderability.
