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.

The following is taken from Application Note

AND8308/D − Interpretation of Datasheet Parameters

for ESD Devices.

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

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.
