Does the ESD-failure current obtained by transmission-line pulsing always correlate to human body model tests?

Two different technologies serve as examples that the degree of correlation between ESD-failure currents obtained by transmission-line pulsing (TLP) and human body model (HBM) is a matter of the technology under investigation. Stressing a device with HBM or TLP can lead to different failure modes and, as a consequence, to a miscorrelation between the two test methods. Optimising a technology or a protection device only by means of TLP can easily lead to false conclusions.
