EMI4182
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.
