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 meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC
61000-4-5 (Surge) requirements.
