Product Description
The CM1213 family of diode arrays has been designed
to provide ESD protection for electronic components or
sub-systems 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 neg-
ative ESD current pulse to either the positive (V
P
) or
negative (V
N
) supply rail. A Zener diode is embedded
between V
P
and V
N
, offering two advantages. First, it
protects the V
CC
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 CM1213 will protect against
ESD pulses up to
±8kV
per the IEC 61000-4-2 stan-
dard and using the MIL-STD-883D (Method 3015)
specification for Human Body Model (HBM) ESD, all
pins are protected from contact discharges of greater
than
±15kV.
This device is particularly well-suited for protecting sys-
tems using high-speed ports such as USB2.0,
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 CM1213 family of devices is available with optional
lead-free finishing.
