Features
Product Description
•
•
•
Four, six or eight channels of ESD protection for
high data rate signals
The CM1209 family of diode arrays are designed to
provide either 4, 6 or 8 channels of ESD protection for
electronic components or sub-systems. Each channel
consists of a pair of diodes which steer the ESD cur-

bance due to these ESD current pulses. The CM1209
devices will protect against ESD pulses up to 15kV
contact discharge per the International Standard

Available in miniature MSOP and SOIC packages
Lead-free versions available
Applications
These devices are particularly well-suited for portable
electronics (e.g. cellular phones, PDAs, notebook com-
puters) because of its small package footprint, high
ESD protection level, and low loading capacitance.
They are also suitable for protecting video output lines
and I/O ports in computers, set top boxes, digital TVs
and peripheral equipment.

Application Information
Design Considerations
In order to realize the maximum protection against
ESD pulses, care must be taken in the PCB layout to
minimize parasitic series inductances on the Supply/
Ground rails as well as the signal trace segment
between the signal input (typically a connector) and the
ESD protection device. Refer to Figure 4, which illus-
trates an example of a positive ESD pulse striking an
input channel. The parasitic series inductance back to

An ESD current pulse can rise from zero to its peak
value in a very short time. As an example, a level 4
contact discharge per the IEC61000-4-2 standard
results in a current pulse that rises from zero to 30
