Revised: 01/21/20
XTREME-GUARDTM ESD Suppressors protect sensitive
electronic equipment against extreme ESD conditions, in
very small 0402 and 0603 footprints. This product series is
specifically designed to suppress fast-rising ESD transients
up to 30kV while adding virtually no capacitance to the
circuit, which helps preserve signal integrity and minimize
data loss. It is RoHS compliant, halogen free and Pb free
ESD Suppressor.

Design Consideration
Because of the fast rise-time of the ESD transient, proper
placement of XTREME-GUARD™ suppressors are a key
design consideration to achieving optimal ESD suppression.
The components should be placed on the circuit board as
close to the source of the ESD transient as possible. Install
XTREME-GUARD™ suppressors (connected from signal/
data line to ground) directly behind the connector so that they
are the first board-level circuit component encountered by the
ESD transient.
Caution: This device should not be used in Power Bus
applications.
