CDSOD323-TxxLC - TVS Diode Series
General Information
The markets of portable communications, computing and video equipment are
challenging the semiconductor industry to develop increasingly smaller electronic
components.

Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection
applications in SOD323 package size format. The Transient Voltage Suppressor Diode
series offers a choice of voltage types ranging from 5 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 meets 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.

1. Part numbers with suffix “C” indicate bidirectional device, i.e. CDSOD323-T05LC.
2. For bidirectional devices only, the electrical specifications apply in both directions.
3. Unidirectional only: Positive potential is applied from pin 1 to 2.
*No lead detected in standard tests of homogeneous materials.
