CM1293
8-Channel Low
Capacitance ESD
Protection Arrays
Product Description
The CM1293 family of diode arrays has been designed to provide
ESD protection for electronic components or sub−systems 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 which steer the positive or negative ESD current pulse to either
the positive (V
embedded between V
protects the V
need for a bypass capacitor that would otherwise be needed for
absorbing positive ESD strikes to ground. The CM1293 will protect
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
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.
