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. 1200 Maximum Forward Current (mA) 1000 800 600 Rth j-a = 10 Rth j-a = 15 Rth j-a = 20 Rth j-a = 25 400 200 C/W C/W C/W C/W 0 25 50 75 100 125 150 175 Ambient Temperature (C) Copyright © 2010 Cree, Inc.
