Description:
* The ESD5Z12 is designed to protect voltage sensitive
components from ESD. Excellent clamping capability, low leakage,
and fast response time provide best in class protection on designs that
are exposed to ESD. Because of its small size, it is suited for use in cellular phones, MP3 players, digital cameras and many other portable
applications where board space is at a premium.
