Functional Description

The CM1220 ESD protection arrays are available in four

and eight channel configurations. Each ESD channel

features a nominal capacitance of 14pF making the devices

ideal for protecting high speed I/O ports and LCD and

camera data lines without significantly affecting signal

integrity. The CM1220 integrates avalanche-type ESD

diodes on every channel, providing a very high level of

protection for sensitive electronic components that may be

subjected to electrostatic discharge (ESD). These diodes

safely dissipate ESD strikes of ±15kV, exceeding the

maximum requirement of the IEC61000-4-2 international

standard. Using the MIL-STD-883 (Method 3015)

specification for Human Body Model (HBM) ESD, the

CM1220 protect against contact discharges at greater than

±30kV.

These devices are particularly well-suited for portable

electronics (e.g. wireless handsets, PDAs, notebook

computers) because of their small package and easy-to-

use pin assignments. In particular, the CM1220 is ideal for

protecting high speed I/O ports and data and control lines

for the LCD display and camera interface in mobile

handsets.

The CM1220 incorporates CMD’s OptiGuardTM coating for

improved reliability at assembly in a space-saving, low-

profile Chip Scale Package.
