14 ther mal design the cxa family of led arrays can include over a hundred different led die inside one package, and thus over a hundred different junction temperatures (t j ). cree has intentionally removed junction ? temperature? based operating limits and replaced the commonplace maximum t j calculations with maximum ratings based on forward current (i f ) and case temperature (tc). no additional calculations are required to ensure the cxa led is being operated within its designed limits. please refer to page 2 for the operating limit specifcation. there is no need to calculate for t j inside the package, as the thermal management design process, specifcally from solder point (t sp ) to ambient (t a ), remains identical to any other led component. for more information on thermal management of cree xlamp leds, please refer to the thermal management application note . for cxa soldering recommendations and more information on thermal interface materials (tim) and connection methods, please refer to the cree xlamp cx family leds soldering and handling document . the cx family led design guide provides basic information on the requirements to use cree xlamp cxa leds successfully in luminaire designs. to keep the cxa1520 led at or below the maximum rated tc, the case to ambient temperature thermal resistance (r_c ? a) must be at or below the maximum r_c? a value shown on the following graph, depending on the operating environment. the y?axis in the graph is a base 10 logarithmic scale. as the fgure at right shows, the r_c ? a value is the sum of the thermal resistance of the tim (r_tim) plus the thermal resistance of the heat sink (r_hs). r_j-c tc r_tim r_hs ta r_j-c tc r_c-a ta cxa1520 . 0.01 0.10 1.00 10.00 100.00 100 200 300 400 500 600 700 800 900 maximum r_c - a current (ma) ta = 25 c ta = 55 c ta = 85 c ta = 105 c copyright ? 2013-2016 cree, inc. all rights reserved. the information in this document is subject to change without notice. cree ? , xlamp ? and easywhite ? are registered trademarks and the cree logo is a trademark of cree, inc. ul ? and the ur logo are registered trademarks of ul llc. xlamp ? cx a 1520 led
