CDSOT953-T05 - Surface Mount TVS Diode
General Information
The CDSOT953-T05 device provides ESD and EFT protection for high speed data
ports meeting IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) requirements. The
Transient Voltage Suppressor array offers a Working Peak Reverse Voltage of 5 V and
Minimum Breakdown Voltage of 6 V.
