View Datasheet Manufacturer Site View Pricing & Stock

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.
