Product Description

The CM1204 is a quad ESD transient voltage supres-

sion diode array. Each diode provides a very high level

of protection for sensitive electronic components that

may be subjected to electrostatic discharge (ESD).

These diodes are designed and characterized to safely

dissipate ESD strikes of +15kV, exceeding the maxi-

mum requirement of the IEC 61000-4-2 international

standard. Using the MIL-STD-883 (Method 3015)

specification for Human Body Model (HBM) ESD, the

device provides protection for contact discharges to

greater than +30kV.

The CM1204 is particularly well suited for portable

electronics (e.g., cellular telephones, PDAs, notebook

computers) because of its small package format and

low weight.

The CM1204 features Optiguard

™ coating which

results in improved reliability at assembly. It is available

in a space-saving, low-profile chip scale package with

optional lead-free finishing.
