CDDFN2-TxxC Series - Surface Mount TVS Diode
General Information
The CDDFN2-TxxC Series provides ESD and EFT protection for external ports of electronic devices
such as cellular phones, hand held electronics and other portable electronic devices.
The device measures 1.05 mm x 0.65 mm and is available in a DFN-2 package and is intended to be
mounted directly onto an FR4 printed circuit board. The device will fit an 0402 footprint.
The device is designed to meet IEC 61000-4-2(ESD) and IEC 61000-4-4(EFT) protection requirements.
