Refer to the Operating Limits section.
OPERATING LIMITS
The maximum current rating of the CXA2520 depends 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 14 for the location of the Tc measurement point.
Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree LED recommends a
maximum LES temperature of 135 °C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 15 for more
information on LES
temperature measurement.

Notes
•
Cree LED 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 16).
•
CXA2520 LED order codes specify only a minimum flux bin and not a maximum. Cree LED 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.

Cree LED 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 16).
•
CXA2520 LED order codes specify only a minimum flux bin and not a maximum. Cree LED 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.

RELATIVE LUMINOUS FLUX
The relative luminous flux values provided below are the ratio of:
• Measurements of CXA2520 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 550 mA at TJ = 85 °C.
For example, at steady-state operation of Tc = 25 °C, IF = 725 mA, the relative luminous flux ratio is 140% in the chart below. A CXA2520
LED that measures 2100 lm during binning will deliver 3300 lm (2940 * 1.4) at steady-state operation of Tc = 25 °C, IF = 725 mA.

XLAMP ® CXA2520 LED
THERMAL 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 (TJ). Cree LED has intentionally removed junction-temperature-based operating limits and replaced the commonplace
maximum TJ calculations with maximum ratings based on forward current (IF) and case temperature (Tc). No additional calculations
are required to ensure that the CXA LED is being operated within its designed limits. LES temperature measurement provides additional
verification of good thermal design. Please refer to page 2 for the Operating Limit specifications.
There is no need to calculate for TJ inside the package, as the thermal management design process, specifically from TSP to ambient (Ta),
remains identical to any other LED component. For more information on thermal management of XLamp LEDs, please refer to the Thermal
Management application note. For CXA soldering recommendations and more information on thermal interface materials (TIM), LES
temperature measurement, and connection methods, please refer to the XLamp CX Family LEDs soldering and handling document. The
CX Family LED Design Guide provides basic information on the requirements to use XLamp CXA LEDs successfully in luminaire designs.
To keep the CXA2520 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
R_j-c
scale.
Tc
Tc
As the figure at right shows, the R_c-a value is the sum of the thermal resistance of the TIM (R_tim)
R_tim
graph, depending on the operating environment. The y‑axis in the graph is a base 10 logarithmic
R_c-a
plus the thermal resistance of the heat sink (R_hs).

NOTES
Measurements
The luminous flux, radiant power, chromaticity, forward voltage and CRI measurements in this document are binning specifications only
and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number
of factors that are not within Cree LED’s control and are not intended or provided as operational specifications for the products. Calculated
values are provided for informational purposes only and are not intended or provided as specifications.
Pre‑Release Qualification Testing
Please read the LED Reliability Overview for details of the qualification process Cree LED applies to ensure long-term reliability for XLamp
LEDs and details of Cree LED’s pre-release qualification testing for XLamp LEDs.
Lumen Maintenance
Cree LED now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen
maintenance. For information on the specific LM-80 data sets available for this LED, refer to the public LM-80 results document.
Please read the Long-Term Lumen Maintenance application note for more details on Cree LED’s lumen maintenance testing and
forecasting. Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive
current affect the LED junction temperature.
RoHS Compliance
The levels of RoHS restricted materials in this product are below the maximum concentration values (also referred to as the threshold
limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 2011/65/EC (RoHS2), as
implemented January 2, 2013. RoHS Declarations for this product can be obtained from your Cree LED representative or from the Product
Ecology section of the Cree LED website.
REACh Compliance
REACh substances of very high concern (SVHCs) information is available for this product. Since the European Chemical Agency (ECHA)
has published notice of their intent to frequently revise the SVHC listing for the foreseeable future, please contact a Cree LED representative
to insure you get the most up-to-date REACh Declaration. REACh banned substance information (REACh Article 67) is also available upon
request.
UL® Recognized Component
This product meets the requirements to be considered a UL Recognized Component with Level 4 enclosure consideration. The LED
package or a portion thereof has been investigated as a fire and electrical enclosure per ANSI/UL 8750.
Vision Advisory
WARNING: Do not look at an exposed lamp in operation. Eye injury can result. For more information about LEDs and eye safety, please
refer to the LED Eye Safety application note.
