CDSOT23-0502B - Surface Mount TVS Diode
General Information
The CDSOT23-0502B bidirectional device provides ESD, EFT and Surge protection
for high speed data ports meeting IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC
61000-4-5 (Surge) requirements. The Transient Voltage Suppressor array offers a
Working Peak Reverse Voltage of 5 V and Minimum Breakdown Voltage of 6 V.
The SOT23-3 packaged device will mount directly onto the industry standard SOT23-3
footprint. Bourns^® Chip Diodes are easy to handle with standard pick and place
equipment and their flat configuration minimizes roll away.
