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.
