CDSOT23-SM712 — Surface Mount TVS Diode
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 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.
