3 ope rating li m its the maximum current rating of the cxb3590 is dependent on the case temperature (tc) when the led has reached thermal equilibrium under steady ? state operation. the graphs shown below assume that the system design employs good thermal management (thermal interface material and heat sink) and may vary when poor thermal management is employed. please refer to the mechanical dimensions section on page 15 for the location of the tc measurement point. 0 400 800 1200 1600 2000 2400 2800 3200 3600 4000 0 25 50 75 100 125 150 if (ma) case temperature ( c) 36 v cxb3590 0 200 400 600 800 1000 1200 1400 1600 1800 2000 0 25 50 75 100 125 150 if (ma) case temperature ( c) 72 v copyright ? 2015-2016 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 ? cxb3590 led

16 therm al design the cxb 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 cxb led is being operated within its designed limits. please refer to page 22 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 cxb soldering recommendations and more information on thermal interface materials (tim) and connection methods, please refer to the cree xlamp cx family l e ds soldering and handling document . the cx family l e d design guide provides basic information on the requirements to use cree xlamp cxb leds successfully in luminaire designs. to keep the cxb3590 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 each 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 0.01 0.10 1.00 10.00 100.00 400 800 1200 1600 2000 2400 2800 3200 3600 maximum r_c - a current (ma) ta = 25 c ta = 55 c ta = 85 c ta = 105 c 36 v copyright ? 2015-2016 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 ? cxb3590 led
