Product Description

The CM1215 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 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. The CM1215 will protect

against ESD pulses up to +15kV per the IEC 61000-4-2

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 CM1215 family of devices is available with

optional lead-free finishing.
