Product Description
The CSPESD304 is a quad ESD transient voltage
supression diode array. Each diode provides a very
high level of protection for sensitive electronic compo-
nents that may be subjected to electrostatic discharge
(ESD). These diodes are designed and characterized
to safely dissipate ESD strikes of 15kV, exceeding the
maximum requirement of the IEC 61000-4-2 interna-
tional 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 CSPESD304 is particularly well suited for portable
electronics (e.g., cellular telephones, PDAs, notebook
computers) because of its small package format and
low weight.
The CSPESD304 is available in a space-saving, low-
profile Chip Scale Package with optional lead-free fin-
ishing.
