Robustness of monochromatic LED modules towards electrostatic discharge events

In this work the robustness of LEDs and LED modules towards ESDs was investigated. A TLP system was used to generate negative-bias ESD pulses. Three different types of LEDs (green, blue and red) were tested, both singularly (with and without the use of an EMCCD camera to detect light emission) and in monochromatic modules. An analysis of the type of failure of the single LEDs was also carried out. The results showed that that different types of devices (and modules) have a different behaviour.
