Transient Voltage Suppressors for ESD Protection
General Description
The ESD8B Series 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 comes at a premium.
