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.
