The ESD7371 Series is designed to protect voltage sensitive
components that require ultra−low capacitance from ESD and
transient voltage events. Excellent clamping capability, low
capacitance, high breakdown voltage, high linearity, low leakage, and
fast response time make these parts ideal for ESD protection on
designs where board space is at a premium. It has industry leading
capacitance linearity over voltage making it ideal for RF applications.
This capacitance linearity combined with the extremely small package
and low insertion loss makes this part well suited for use in antenna
line applications for wireless handsets and terminals.

The following is taken from Application Note
AND8308/D − Interpretation of Datasheet Parameters
for ESD Devices.
from a 100 ns long rectangular pulse from a charged
transmission line. A simplified schematic of a typical TLP
system is shown in Figure 9. TLP I−V curves of ESD
protection devices accurately demonstrate the product’s
ESD capability because the 10s of amps current levels and
under 100 ns time scale match those of an ESD event. This
is illustrated in Figure 10 where an 8 kV IEC 61000−4−2
current waveform is compared with TLP current pulses at
8 A and 16 A. A TLP I−V curve shows the voltage at which
the device turns on as well as how well the device clamps
voltage over a range of current levels.
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.
