TLP is able to obtain current versus voltage (I−V) curves in which each data point is obtained with a 100 ns 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 datasheet parameters extracted from TLP for SDI Technology’s protection products Comparison of a Current Waveform of IEC 61000−4−2w ith TLP Pulses at 8 and 16 A. The IEC 61000−4−2 ESD waveforms is true to the Standard and is shown here as captured on an oscilloscope. The points A, B, and C show the points on the aveforms specified in IEC 61000−4−2.

Such steps are listed below. 1. Place the ESD protection device as close as possible to the I/O connector to reduce the ESD path to ground andimprove the protection performance. 1.1. In USB 3.0/3.1 applications, the ESD protection device should be placed between the AC coupling capacitors and the I/O connector on the TX differential lanes as shown in below drawing In this configuration, no DC current can flow through the ESD protection device preventing any potential latch-up condition. For more information on latchup considerations, see below description on below drawing. 2. Make sure to use differential design methodology and impedance matching of all high speed signal traces. 2.1. Use curved traces when possible to avoid unwanted reflections. 2.2. Keep the trace lengths equal between the positive and negative lines of the differential data lanes to avoid common mode noise generation and impedance mismatch. 2.3. Place grounds between high speed pairs and keep asmuch distance between pairs as possible to reduce crosstalk.
