## **Features** n RoHS compliant* n Working peak voltage 7 V or 12 V n ESD protection 30 kV max. n Surge protection ## **Applications** n Wireless systems n Network protection n Portable electronics n RS-485 port protection ## **CDSOT23-SM712 - Surface Mount TVS Diode** BOURNS [\ ## ~~**General Information**~~ 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 two TVS diodes with a Working Peak Reverse Voltage of 7 V or 12 V and 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. 1 3 2 ## ~~**Absolute Maximum Ratings (@ TA = 25 °C Unless Otherwise Noted)**~~ |**Parameter**|**Symbol**|**Value**|**Unit**| |---|---|---|---| |Peak Pulse Power (tp= 8/20 µs)1|PPK|400|W| |Peak Pulse Current (8/20 µs)|IPP|17|A| |Storage Temperature|TSTG|-55 to +150|ºC| |Operating Temperature|TOPR|-55 to +150|ºC| ## ~~**Electrical Characteristics (@ TA = 25 °C Unless Otherwise Noted)**~~ |**Parameter**|**Symbol**|**Value**|**Unit**| |---|---|---|---| |Minimum Breakdown Voltage @ 1 mA
