system is shown in Figure 8. TLP I−V curves of ESD
protection devices accurately demonstrate the product’s
DUT
ESD capability because the 10s of amps current levels and
V
C
under 100 ns time scale match those of an ESD event. This
Oscilloscope
is illustrated in Figure 9 where an 8 kV IEC61000−4−2
current waveform is compared with TLP current pulses at

8 A and 16 A. A TLP I−V curve shows the voltage at which
System
the device turns on as well as how well the device clamps
voltage over a range of current levels. A typical TLP I−V
curve for the ESD7383 is shown in Figures 6 and 7.
