WebJun 7, 2011 · The maximum junction temperature (T) attained with a given power input is determined by three factors: ambient temperature, thermal resistance between the LED junction and its surroundings, and the power dissipated by the chip.¹. For ease of calculation, let's assume an ambient temperature (T a) of 23 degrees Celsius (°C). Webunder electrical bias is the junction temperature (TJ) of the silicon. Figure 2 shows how the onset of EM changes with TJ on a TI proprietary silicon node. Note that EM performance may differ per technology but the principle of fail rate vs temperature will apply: running at temperature extremes for long durations above 105°C will shorten the ...
