ESD Protection Arrays
CM1213A
Features
• One, two, and four channels of ESD protection
Note: For 6- and 8-channel devices, see the
CM1213 datasheet.
• Provides ESD protection to IEC61000-4-2
Level 4
±8kV contact discharge

strikes*
• Available in SOT, SC70, and MSOP RoHS-
compliant, lead-free packages
Applications
• USB2.0 ports at 480Mbps in desktop PCs,
notebooks and peripherals
• IEEE1394 Firewire® ports at 400Mbps /
800Mbps
• 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

Product Description
The CM1213A 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
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. The CM1213A will protect against ESD
pulses up to 8kV per the IEC 61000-4-2 standard.
These devices are 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.
The CM1213A family of devices is available with
RoHS-compliant, lead-free finishing.
