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 (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 CM1293 will protect against ESD pulses up to ( ±15kV air, ±8kV contact discharge) per the IEC 61000-4-2 Level 4 standard. 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 CM1293 family of devices is available with optional lead-free finishing.
