CM1224-04SO ESD Protection Diodes by ON Semiconductor

Low Capacitance ESD Protection Arrays


The CM1224 family of diode arrays has been 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, offering two advantages. First, it protects the VCC 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 CM1224 protects 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 USB 2.0, IEEE1394 (Firewire®, iLink™), Serial ATA, DVI, HDMI and corresponding ports in removable storage, digital camcorders, as well as DVD-RW drives and other applications where extremely low loading capacitance with ESD protection are required. The CM1224 family of devices has lead-free finishing in a small package footprint.
