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.

Transmission Line Pulse (TLP) Measurement

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 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.
