CM1293A
2 and 4-Channel
Low Capacitance
ESD Protection Arrays
Product Description
The CM1293A family of diode arrays has been designed to provide
ESD protection for electronic components or subsystems requiring
minimal capacitive loading. These devices are ideal for protecting
systems with high data and clock rates or for circuits requiring low
capacitive loading. Each ESD channel consists of a pair of diodes in
series that steer the positive or negative ESD current pulse to either the
positive (V
P
) or negative (V
N
) supply rail. A Zener diode is embedded
between V
P
and V
N
which helps protect the V
CC
rail against ESD
strikes. The CM1293A protects against ESD pulses up to
±8
kV
contact discharge) per the IEC 61000−4−2 Level 4 standard.
This device is particularly well−suited for protecting systems using
high−speed ports such as USB2.0, IEEE1394 (FireWire
®
, i.LINKt),
Serial ATA, DVI, HDMI, and corresponding ports in removable
storage, digital camcorders, DVD−RW drives and other applications
where extremely low loading capacitance with ESD protection are
required in a small package footprint.

*Standard test condition is IEC61000−4−2 level 4 test circuit with each pin
subjected to
±8
kV contact discharge for 1000 pulses. Discharges are timed at
1 second intervals and all 1000 strikes are completed in one continuous test run.
The part is then subjected to standard production test to verify that all of the
tested parameters are within spec after the 1000 strikes.
