Product Description CM1213A−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 which steer the positive or
negative ESD current pulse to either the positive (VP) or negative (VN)
supply rail. A Zener diode is embedded between VP and VN, offering
two advantages. First, it protects the VCC rail against ESD strikes, and
second, it eliminates the need for a bypass capacitor that would
otherwise be needed for absorbing positive ESD strikes to ground.
This device will protect against ESD pulses up to 8 kV per the
IEC 61000−4−2 standard.
This device is particularly well-suited for protecting systems using
high-speed ports such as USB 2.0, IEEE1394 (Firewire , iLink�),
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.

Applications USB2.0 Ports at 480 Mbps in Desktop PCs, Notebooks and Peripherals IEEE1394 Firewire Ports at 400 Mbps/800 Mbps DVI Ports, HDMI Ports in Notebooks, Set Top Boxes, Digital TVs,
LCD Displays Serial ATA Ports in Desktop PCs and Hard Disk Drives PCI Express Ports General Purpose High−Speed Data Line ESD Protection
**Standard test condition is IEC61000−4−2 level 4 test circuit with each pin subjected to 8 kV contact discharge for 1000 pulses. Dischargesare timed at 1 second intervals and all 1000 strikes are completed in one continuous test run. The part is then subjected to standard productiontest to verify that all of the tested parameters are within spec after the 1000 strikes.
