General
The DF2B12M4SL 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 DF2B12M4SL provides low dynamic resistance and superior protective
performance.
Furthermore, it is optimum the high speed signal application for the low capacitance performance. The
DF2B12M4SL is housed in an ultra-compact package (0.62 mm × 0.32 mm) to meet applications that require a
small footprint.
