1. Part numbers with suffix “C” indicate bidirectional device, i.e. CDSOD323-T05SC.
2. For bidirectional devices only, the electrical specifications apply in both directions.
General Information
Portable communications, computing and video equipment manufacturers 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 series
offers a choice of voltage types ranging from 3 V to 36 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.
