Transient Voltage
Suppressors
Micro−Packaged Diodes for ESD Protection
The ESD9B 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.

AND8308/D − Interpretation of Datasheet Parameters
for ESD Devices.
systems such as cell phones or laptop computers it is not
clearly defined in the spec how to specify a clamping voltage
at the device level. ON Semiconductor has developed a way
to examine the entire voltage waveform across the ESD
protection diode over the time domain of an ESD pulse in the
form of an oscilloscope screenshot, which can be found on
the datasheets for all ESD protection diodes. For more
information on how ON Semiconductor creates these
screenshots and how to interpret them please refer to
AND8307/D.
ESD Voltage Clamping
For sensitive circuit elements it is important to limit the
voltage that an IC will be exposed to during an ESD event
to as low a voltage as possible. The ESD clamping voltage
is the voltage drop across the ESD protection diode during
an ESD event per the IEC61000−4−2 waveform. Since the
IEC61000−4−2 was written as a pass/fail spec for larger
