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 negative 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 standard.
These devices are particularly well-suited for
protecting systems 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.
