General Information
Absolute Maximum Ratings (@ TA= 25 °C Unless Otherwise Noted)
The CDSOT23-SM712 device provides ESD, EFT and Surge protection for 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 2 TVS diodes with
Working Peak Reverse Voltage of 7 V or 12 V with Minimum Breakdown Voltage of
7.5 V or 13.3 V respectively.
The SOT23 packaged device will mount directly onto the industry standard SOT23
footprint. Bourns®Chip Diodes conform to JEDEC standards, are easy to handle with
standard pick and place equipment and the flat configuration minimizes roll away.
*RoHS COMPLIANT
*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.
