Cree® TR5270M™ LEDs
CxxxTR5270M-Sxx000 (175-μm)
CxxxTR5270M-Sxx000-3 (250-μm)
Data Sheet
Cree’s TR5270M 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 TR5270M 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 TR5270M is available
in two chip thicknesses: 175 μm and 250 μm. The 250-μm-thick version offers 5% improvement brightness over the
175-μm version due the increased bevel area. 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.

All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled and operated at 120
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 clear epoxy 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.
