DESCRIPTION
PSD03-PSD36C
The PSDxx and PSDxxC Series are transient voltage suppressor
arrays designed for ESD protection of SMART phones,
laptop computers and other portable electronics. These silicon
based diodes offer superior clamping voltage and performance
compared to other technologies such as MLVs.

UNIDIRECTIONAL
The PSDxx and PSDxxC Series can be utilized as a
single line protector in either a unidirectional or
bidirectional configuration. The SOD-323 small package configu-
ration offers designers the flexibility of placement on the printed
circuit
board for each I/O port or voltage bus. The PSDxx and PSDxxC
Series meets the IEC 61000-4-2 (ESD), 61000-4-4 (EFT)
and 61000-4-5 requirements.
