Product Description
The CSPESD301/302/303 is 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 protec-
tion for nodes that have AC signals up to 5.9V peak.
These devices provide a very high level of protection
for sensitive electronic components that may be sub-
jected to electrostatic discharge (ESD). The diodes
are designed and characterized to safely dissipate
ESD strikes of ±15kV, well beyond the maximum
requirements of the IEC 61000-4-2 international stan-
dard. Using the MIL-STD-883 (Method 3015) specifica-
tion for Human Body Model (HBM) ESD, these devices
protection against contact discharges at 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 CSPESD301/2/3 is available in a space-saving,
low-profile, chip-scale package with optional lead-free
finishing.
