ESD7424
Ultra-Low Capacitance ESD
Protection
Micro−Packaged Diodes for ESD Protection
The ESD7424 is designed to protect voltage sensitive components
that require ultra−low capacitance from ESD and transient voltage
events. 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.

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

Transmission Line Pulse (TLP) provides current versus
voltage (I−V) curves in which each data point is obtained
from a 100 ns long rectangular pulse from a charged
transmission line. A simplified schematic of a typical TLP
system is shown in Figure 11. 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 12 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.
