Model CDDFN2-T5.0LC low capacitance device provides ESD and EFT
protection for external ports of electronic devices such as cellular phones, handheld
electronics and other portable electronic devices.
The device measures 1.0 mm x 0.60 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 a
0402 footprint.
The device is designed to meet IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT)
protection requirements.
