CM1220
4 and 8-Channel ESD
Protection Arrays in CSP
Description
The CM1220 ESD protection arrays are available in four and eight
channel configurations. Each ESD channel features a nominal
capacitance of 14 pF 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 ±15 kV, 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 ±30 kV.
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 ON Semiconductor’s OptiGuardt
coating for improved reliability at assembly in a space−saving,
low−profile Chip Scale Package.
