TR3547M

Cree® TR3547M™ LEDs
CxxxTR3547M-Sxx00
Data Sheet
Cree’s TR3547M 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 TR3547M 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 metal backside allows for eutectic
die attach and enables superior performance from improved thermal management. 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
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).
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 intrinsic AuSn metal die
attach). Optical characteristics measured in an integrating sphere using Illuminance E.

Standard Bins for CxxxTR3547M-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 (CxxxTR3547M-Sxxxx) orders may be filled with any or all bins (CxxxTR3547M-xxxx)
contained in the kit. All radiant flux and dominant wavelength values shown and specified are at If = 50 mA.
