ON ESD7481 Esd protection diode Datasheet

ESD7481, SZESD7481
ESD Protection Diodes
Micro−Packaged Diodes for ESD Protection
The ESD7481 is designed to protect voltage sensitive components
that require ultra−low capacitance from ESD and transient voltage
events. Excellent clamping capability, low capacitance, low leakage,
and fast response time, make these parts ideal for ESD protection on
designs where board space is at a premium. Because of its low
capacitance, the part is well suited for use in high frequency designs
such as USB 2.0 high speed and antenna line applications.

ESD Voltage Clamping
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.
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
