Cree® XLamp® ML-E LEDs
PRODUCT DESCRIPTION
The Cree XLamp® ML-E LED
brings lighting-class reliability and
performance to ½-watt LEDs. The
XLamp ML-E LED expands Cree’s
lighting-class leadership to LED
bulbs and linear and distributed
lighting applications. With XLamp
LED lighting-class reliability, a wide
viewing angle, uniform light output, and
industry-leading chromaticity binning in
a 3.5-mm X 3.5-mm package, the XLamp
ML-E LED continues Cree’s history of
segment-focused product innovation in
LEDs for lighting applications.
The XLamp ML-E LED brings high
performance and a smooth look to a
wide range of lighting applications,
including linear lighting, LED light bulbs,
uorescent retrots and retail-display
lighting.

THERMAL DESIGN - PARALLEL WHITE
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is crucial for the end
product to be designed in a manner that minimizes the thermal resistance from the solder point to ambient in order to optimize lamp life
and optical characteristics.

REFLOW SOLDERING CHARACTERISTICS
In testing, Cree has found XLamp ML-E LEDs to be compatible with JEDEC J-STD-020C, using the parameters listed below. As a general
guideline, Cree recommends that users follow the recommended soldering prole provided by the manufacturer of the solder paste used.
Note that this general guideline may not apply to all PCB designs and congurations of reow soldering equipment.
Profile Feature Lead-Free Solder
Average Ramp-Up Rate (Tsmax to Tp) 1.2°C/second
Preheat: Temperature Min (Tsmin) 120 °C
Preheat: Temperature Max (Tsmax) 170 °C
Preheat: Time (tsmin to tsmax) 65-150 seconds
Time Maintained Above: Temperature (TL) 217 °C
Time Maintained Above: Time (tL)45-90 seconds
Peak/Classication Temperature (Tp) 235 - 245 °C
Time Within 5°C of Actual Peak Temperature (tp) 20-40 seconds
Ramp-Down Rate 1 - 6 °C/second
Time 25°C to Peak Temperature 4 minutes max.
Note: All temperatures refer to topside of the package, measured on the package body surface.
Note: While the high reow temperatures (above) have been approved, Cree’s best practice guideline for reow is to use as low a
temperature as possible during the reow soldering process for these LEDs.

NOTES
Measurements
The luminous ux, radiant power, chromaticity, forward voltage and CRI measurements in this document are binning specications 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’s control and are not intended or provided as operational specications for the products. Calculated
values are provided for informational purposes only and are not intended as specications.

Please read the LED Reliability Overview for details of the qualication process Cree applies to ensure long-term reliability for XLamp
LEDs and details of Cree’s pre-release qualication testing for XLamp LEDs.
Lumen Maintenance
Cree 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 specic 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’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.
Moisture Sensitivity
Cree recommends keeping XLamp ML-E LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately prior to
soldering. Unopened MBPs that contain XLamp LEDs do not need special storage for moisture sensitivity.
Once the MBP is opened, XLamp ML-E LEDs should be handled and
stored as MSL 2a per JEDEC J-STD-033, meaning they have limited
exposure time before damage to the LED may occur during the soldering
operation. The table on the right species the maximum exposure time
in days depending on temperature and humidity conditions. LEDs with
exposure time longer than the specied maximums must be baked
according to the baking conditions listed below.
Baking Conditions
It is not necessary to bake all XLamp ML-E LEDs. Only the LEDs that meet all of the following criteria must be baked:
1. LEDs that have been removed from the original MBP.
2. LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above.
3. LEDs that have not been soldered.

23
XLamp® mL-E LED
LEDs should be baked at 70ºC for 24 hours. LEDs may be baked on the original reels. Remove LEDs from the MBP before baking. Do
not bake parts at temperatures higher than 70ºC. This baking operation resets the exposure time as dened in the Moisture Sensitivity
section above.
Storage Conditions
XLamp ML-E LEDs that have been removed from the original MBP but not soldered should be stored in one of the following ways:
• Store the parts in a rigid metal container with a tight-tting lid. Verify that the storage temperature is <30°C, and place fresh desiccant
and an RH indicator in the container to verify that the RH is no greater than 60%.
• Store the parts in a dry, nitrogen-purged cabinet or container that actively maintains the temperature at <30° and the RH at no greater
than 60%.
• For short-term store only: LEDs can be resealed in the original MBP soon after opening. Fresh desiccant may be needed. Use the
included humidity indicator card to verify <60% RH.
If an environment of <60% RH is not available for storage, XLamp ML-E LEDs should be baked (described above) before reow soldering.
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 representative or from the Product
Documentation sections of www.cree.com.
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 representative to
insure you get the most up-to-date REACh SVHC Declaration. REACh banned substance information (REACh Article 67) is also available
upon request.
UL® Recognized Component
Level 4 enclosure consideration. The LED package or a portion thereof has been investigated as a re 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.
