THERMAL DESIGN
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-B 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 profile provided by the
manufacturer of solder paste used.
Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment.

Note: All temperatures refer to topside of the package, measured on the package body surface.
Note: While the high reflow temperatures (above) have been approved, Cree’s best practice guideline for reflow is to use
as low a temperature as possible during the reflow soldering process for these LEDs.

NOTES
Lumen Maintenance Projections
Cree currently recommends a maximum drive current of 80 mA for XLamp ML-B white in designs seeking the ENERGY
STAR* 35,000 hour lifetime rating (≥ 94.1% luminous flux @ 6000 hours) or 25,000-hour lifetime rating (≥ 91.8%
luminous flux @ 6000 hours).
Please read the XLamp Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance
testing and forecasting. Please read the XLamp Thermal Management application note for details on how thermal design,
ambient temperature, and drive current affect the LED junction temperature.
* These lifetime ratings are based on the current ENERGY STAR Solid State Lighting Luminaires V1.1 (December 12,
2008) and ENERGY STAR Integral LED Lamps V1.0 (December 3, 2009) lumen maintenance criteria.
Moisture Sensitivity
In testing, Cree has found XLamp ML-B LEDs to have unlimited floor life in conditions ≤30ºC / 85% relative humidity
(RH). Moisture testing included a 168 hour soak at 85ºC / 85% RH followed by 3 reflow cycles, with visual and electrical
inspections at each stage.
RoHS Compliance
The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or otherwise 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 2002/95/
EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), as
amended through April 21, 2006.
Vision Advisory Claim
Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye.
