CDSOD323-TxxC - TVS Diode Array Series
General Information
UNIDIRECTIONAL
1
Portable communications, computing and video equipment manufacturers are challenging
the semiconductor industry to develop increasingly smaller electronic components.
BIDIRECTIONAL
1
Bourns offers Transient Voltage Suppressor Array diodes for surge and ESD protection
applications, in SOD323 package size format. The Transient Voltage Supressor Array series
offers a choice of voltage types ranging from 3 V to 24 V in a unidirectional or bidirectional
configuration. Bourns Chip Diodes conform to JEDEC standards, are easy to handle on
standard pick and place equipment and their flat configuration minimizes roll away.
The Bourns® device will assist compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT)
and IEC 61000-4-5 (Surge) requirements.

Note: For 12 V and 24 V VDSL applications, the CDSOD323-TxxC-DSL family of
devices is recommended.
