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.
