CM1293A-04SO_12 Datasheet, PDF (1/6 Pages) ON Semiconductor – 4-Channel Low Capacitance ESD Protection Array

CM1293A-04SO
4-Channel
Low Capacitance
ESD Protection Array
Product Description
CM1293A−04SO has been designed to provide ESD protection for
electronic components or subsystems requiring minimal capacitive
loading. This device is 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. This device 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.
