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. 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 CM1213A will protect

against ESD pulses up to 12 kV per the IEC 61000?4?2 standard.
