CDSOD323-T24C-DSLQ - TVS Diode Series
General Information
Portable communications and telecom equipment manufacturers are challenging the
semiconductor industry to develop increasingly smaller electronic components for high-
speed communication rates.
Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection
applications in SOD323 package size format. Bourns® Chip Diodes conform to JEDEC
The Bourns® device will assist compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4
(EFT) and IEC 61000-4-5 (Surge) requirements.
