tAbLE of ContEnts
Thꢀ XLamp® CXA1520 LED is Cree’s first
High Density (HD) LED array, featuring
a 9‑mm optical source and enabling
lighting manufacturers to create a new
generation of products that delivers the
same intensity and light quality as 39‑W
ceramic metal halide (CMH) at up to 50
percent lower power. The new HD class
of CXA arrays provide unrivaled lumen
density that can reduce system cost for
the next generation of LED spotlights.

The maximum current rating of the CXA1520 is dependent on the case temperature (Tc) when the LED has reached thermal equilibrium
under steady‑state operation. The graph shown below assumes 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 13 for the location of the Tc measurement point.

Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI
measurements. See the Measurements section (page 15).
Cree XLamp CXA1520 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.
Flux values @ 25 °C are calculated and for reference only.

The relative luminous flux values provided below are the ratio of:
•
•
Measurements of CXA1520 at steady‑state operation at the given conditions, divided by
Flux measured during binning, which is a pulsed measurement at 500 mA at T = 85 °C.
J
For example, at steady‑state operation of Tc = 105 °C, IF = 700 mA, the relative luminous flux ratio is 120% in the chart below. A CXA1520
LED that measures 2100 lm during binning will deliver 2520 lm (2100 * 1.2) at steady‑state operation of Tc = 105 °C, IF = 700 mA.

XLamp® CXa1520 LED
thEꢀMAL 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 ). Cree has intentionally removed junction‑temperature‑based operating limits and replaced the commonplace maximum
J
T calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations are required to
J
ensure the CXA LED is being operated within its designed limits. Please refer to page 2 for the Operating Limit specification.
There is no need to calculate for T inside the package, as the thermal management design process, specifically from solder point (TSP) to
J
ambient (Ta), 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
R_j-c
Tc
R_j-c
Tc
graph, depending on the operating environment. The y‑axis in the graph is a base 10 logarithmic
scale.
R_tim
As the figure 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).
