Product Description
The CM1213A 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.
