Product Description

The CM1213A family of diode arrays has been designed to provide ESD protection for electronic

components or sub-systems 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 apair of diodes in series which steer the positive or negative ESD current pulse to either the positive(VP) or negative (VN) supply rail.
