Product Description
The CM1203 comprises a family of 1, 2, and 3-channel
ESD protection arrays, which integrate two, three and
four identical avalanche-style diodes. It is intended that
one of these diodes is connected to GND and the other
diodes provide ESD protection for up to 3 lines
depending upon the configuration utilized. The back-
to-back diode connections provide ESD protection for
nodes that have AC signals up to 5.9V peak. These
devices provide a very high level of protection for sen-
sitive electronic components that may be subjected to
electrostatic discharge (ESD). The diodes are
designed and characterized to safely dissipate ESD
strikes of ±15kV, well beyond the maximum require-
ments of the IEC 61000-4-2 international standard.
Using the MIL-STD-883 (Method 3015) specification
for Human Body Model (HBM) ESD, these devices pro-
tect against contact discharges of greater than ±30kV.
The diodes also provide some EMI filtering, when used
in combination with a PCB trace or series resistor.
These devices are particularly well-suited for portable
electronics (e.g. cellular telephones, PDAs, notebook
computers) because of their small package format and
easy-to-use pin assignments.
The CM1203 incorporates OptiGuard™ coating which
results in improved reliability at assembly. The CM1203
is available in a space-saving, low-profile, chip-scale
package with optional lead-free finishing.
