DF2B7ACT ESD Protection Diodes Silicon Epitaxial Planar DF2B7ACTDF2B7ACTDF2B7ACTDF2B7ACT 1. 1. GeneralGeneral 1. 1. GeneralGeneral The DF2B7ACT 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 DF2B7ACT provides low dynamic resistance and superior protective performance. Furthermore, it is optimum the high speed signal application for the low capacitance performance. The DF2B7ACT is housed in an ultra-compact package (1.0 mm 0.6 mm) to meet applications that require a small footprint. 2. 2. 2. 2.
