CDDFN2-T3.3C - Surface Mount TVS Diode
General Information
The CDDFN2-T3.3C device provides ESD, EFT and Surge 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 x 0.55 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), IEC 61000-4-4 (EFT) and IEC61000-4-5 (Surge)
protection requirements.
