The CM1204 is a quad ESD transient voltage supression
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
safely dissipate ESD strikes of ±15kV, exceeding the
maximum 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 ^TM coating which results in
improved reliability at assembly. It is available in a space-
saving, low-profile chip scale package with RoHS-
compliant lead-free finishing.
