®
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.
