CSPESD304
4-Channel ESD Array in CSP
Product Description
The CSPESD304 is a quad ESD transient voltage suppression 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 ± 15 kV,
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 ± 30 kV.
The CSPESD304 is particularly well ? suited for portable electronics
(e.g., cellular telephones, PDAs, notebook computers) because of its
small package and low weight.
The CSPESD304 is available in a space ? saving, low ? profile Chip
Scale Package with lead ? free finishing.
