Product Description

The CM1223 family of diode arrays are designed to provide

ESD protection for electronic components or subsystems

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 (VP) or negative (VN) supply rail. A Zener diode is

embedded between VP and VN, to absorb positive ESD

strikes and provide ESD protection for the VP rail. An

additional diode is integrated to serve as backdrive current

protection. The CM1223 protects against ESD pulses up to

±8kV per the IEC 61000-4-2 standard. In addition, all pins

are protected from contact discharges of greater than

±15kV as outlined by the MIL-STD-883D (Method 3015)

specification for Human Body Model (HBM) ESD.

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, as well as other applications

where extremely low loading capacitance with ESD

protection are required in a small package footprint.

The CM1223 family of devices are manufactured with

RoHS-compliant, lead-free packaging.
