General

The DF2B7AFU is a TVS diode (ESD protection diode) protects semiconductor devices used in mobile device

interfaces and other applications to protect against static electricity and noise.

Utilizing snapback characteristics, the DF2B7AFU provides low dynamic resistance and superior protective

performance.

Furthermore, it is optimum the high speed signal application for the low capacitance performance. The DF2B7AFU

is housed in an ultra-compact package (2.5 mm × 1.25 mm) to meet applications that require a small footprint.
