Transmission Line Pulse (TLP) Measurements
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 10 s
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
IEC61000-4-2 current waveform is compared with TLP current pulses at 8 and 16 A. A TLP 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. Typical TLP I-V curves for
the EMI4182 are shown in Figure 13.

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 On Semiconductor
Application Notes AND8307/D and AND8308/D.
