TR3547™ LEDs
Data Sheet
CxxxTR3547-Sxx00
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 industry-
standard top-view packages.

Notes:
1. 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.

Standard Bins for CxxxTR3547-Sxx00
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 (CxxxTR3547-Sxxxx) orders may be filled with any or all bins (CxxxTR3547-xxxx) contained
in the kit. All radiant flux and dominant wavelength values shown and specified are at If = 50 mA.
