Direct Attach DA1000™ LEDs
CxxxDA1000-Sxx000
Data Sheet
Cree’s Direct Attach DA1000 LEDs are the next generation of solid-state LED emitters that combine highly efficient
InGaN materials with Cree’s proprietary device technology and silicon-carbide substrates to deliver superior value for
the general-illumination market. The DA1000 LEDs are among the brightest in the lighting market while delivering
a low forward voltage, resulting in a very bright and highly efficient solution. The bondpad-down design allows for
a eutectic direct die-attach process, eliminating the need for wire bonds, and enables superior performance from
improved thermal management.

Maximum ratings are package-dependent. The above ratings were determined using a Cree 3.45-mm x 3.45-mm SMT package (with silicone
encapsulation and intrinsic AuSn metal die attach) for characterization. Ratings for other packages may differ. Junction temperature should be
characterized in a specific package to determine limitations. Assembly processing temperature must not exceed 325°C (< 5 seconds).
All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled and operated at 350
mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given are within the range of average values
expected by manufacturer in large quantities and are provided for information only. All measurements were made using lamps in T-1¾ packages (with
Hysol OS4000 epoxy encapsulant and intrinsic AuSn metal die attach). Optical characteristics measured in an integrating sphere using Illuminance E.
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 LED junction to ambient in order to optimize product performance.

Standard Bins for CxxxDA1000-Sxx000
LED chips are sorted to the
radiant flux
and
dominant wavelength
bins shown. A sorted die sheet contains die
from only one bin. Sorted die kit (CxxxDA1000-Sxxxxx) orders may be filled with any or all bins (CxxxDA1000-xxxxx)
contained in the kit. All radiant flux and dominant wavelength values shown and specified are at If = 350 mA.
