Cree® TR3547™ LEDs CxxxTR3547-Sxx00 Data Sheet Cree’s TR3547 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 TV-backlighting and general-illumination markets. The TR3547 LEDs are among the brightest in the top-view market while delivering a low forward voltage, resulting in a very bright and highly efficient solution. The design is optimally suited for industrystandard top-view packages. FEATURES APPLICATIONS • • Rectangular LED RF performance – 450 & 460 nm – 70 mW min Large LCD backlighting – Television • Low forward voltage - 3.2 Vf typical at 50 mA • General illumination • Maximum DC forward current – 150 mA • Medium LCD backlighting • 1000-V ESD threshold rating – Portable PCs • InGaN junction on thermally conductive SiC – Monitors substrate • LED video displays • White LEDs CxxxTR3547-Sxx00 Chip Diagram Die Cross Section Top View Bottom View A CPR3FJ Rev.

Maximum ratings are package-dependent. The above ratings were determined using a Cree SMT package (with silicone encapsulation) 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). 2. Product resistance to electrostatic discharge (ESD) according to the HBM is measured by simulating ESD using a rapid avalanche energy test (RAET). The RAET procedures are designed to approximate the maximum ESD ratings shown. 3. All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled and operated at 50 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-1 3/4 packages (with Hysol OS4000 epoxy encapsulant and silicone die attach). Optical characteristics measured in an integrating sphere using Illuminance E. Copyright © 2011-2012 Cree, Inc. All rights reserved.
