WebSince Rth (j-a) is 250 deg./W, the junction temperature rises by 25 deg. per each increment of 0.1W of current consumption. This means, the junction temperature becomes 150 deg. when the current consumption is 0.5W, and the graph in this case suggests that the current beyond 0.5W can not be applied to TR.

WebTo calculate the maximum power dissipation at Tc (case temperature) = 25degC, you can simply substitute Tc for Ta and RthetaJC for RthetaJA as follows: PD = (Tj - Tc)/RthetaJC = (150 - 25) / 1.8degC/W = 69.4W. WebIo : Rated ripple current at maximum operating temperature I : Actual ripple current 2. Ambient Temperature Calculation Formula If measuring ambient temperature (Ta) is difficult, Ta can be calculated from surface temperature of the capacitor as follows. Tj Ta Tc = − Ta : Calculated ambient Temperature Tc : Surface Temperature of capacitor

WebThe temperature rise is then 4.41 W * 5.3 C/W = 23.4 C and the junction temperature is 52 C + 23.4 C = 75.4 C. This LED is operating well below the 115 C Tj max limit in the datasheet. A board temperature of 52 C implies that the heat extraction path at the system level is over engineered and cost can be reduced by redesigning it.
