Characteristic Curves

Transmission Line Pulse (TLP)

ESD2.5V88D-CDN

Transmission Line Pulse (TLP) is a measurement technique used in the Electrostatic Discharge (ESD) arena to characterize

performance attributes of devices under ESD stresses. TLP is able to obtain current versus voltage (I−V) curves in which each

data point is obtained with a 100ns long pulse, with currents up to 40 A. TLP was first used in the ESD field to study human

body model (HBM) in integrated circuits, but it is an equally valid tool in the field of system level ESD. The applicability of TLP to

system level ESD is illustrated in Figure 1, which compares an 8 KV IEC 61000−4−2 current waveform with TLP current pulses

of 8 and 16 A. The current levels and time duration for the pulses are similar and the initial rise time for the TLP pulse is

comparable to the rise time of the IEC 61000−4−2’s initial current spike. This application note will give a basic introduction to

TLP measurements and explain the data sheet parameters extracted from TLP for SDI Technology’s protection products
