Description
XTREME-GUARD
TM
ESD Suppressors protect sensitive
electronic equipment against extreme ESD conditions, in
very small 0402 and 0603 footprints. This series product 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 designed as RoHS compliant, halogen free,
and Pb free.
Features
• High ESD Rating up to
30kV Contact/Air
Discharge
• RoHS compliant, lead-free
and halogen-free
• Ultra-low capacitance
• Low leakage current
• Fast response time
• Bi-directional
• Withstands multiple
ESD strikes
Applications
• Compatible with
pick-and-place processes
• Available in 1000, 5000,
and 10000 piece reels
(EIA-RS481)
• High rated voltage up to
32V maximum
• High operating
temperature at 125ºC

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 devices 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.
