Overview
The CM1213A-04MR, produced by onsemi, is a 4-channel low capacitance ESD (Electrostatic Discharge) protection array. This device is designed to provide ESD protection for electronic components or subsystems that require minimal capacitive loading. It is particularly suitable for systems with high data and clock rates, such as those using USB 2.0, IEEE1394 (Firewire), Serial ATA, DVI, and HDMI ports. The CM1213A-04MR features a unique design with a pair of diodes in series for each ESD channel, steering positive or negative ESD current pulses to the supply rails, and an embedded Zener diode to protect the VCC rail and eliminate the need for a bypass capacitor.
