Product Description
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-
rent pulse either to the positive (V
P
) or negative (V
N
)
supply. In addition, there is an integral Zener diode
between V
P
and V
N
to suppress any voltage distur-
bance due to these ESD current pulses. The CM1209
devices will protect against ESD pulses up to 15kV
contact discharge per the International Standard
IEC61000-4-2.
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.
The CM1209 family of devices is optionally available
with lead-free finishing.
