Description
Cree's UBTM series of UltraBrightTM LEDs combine highly efficient InGaN materials with Cree's
proprietary G
SiC substrate to deliver excellent price performance for high intensity blue and green
LEDs. UltraBright LED chips are available in a geometrically enhanced vertical structure or a straight-
wall design for use in reflector-less applications such as ChipLEDs. Both require only a single wire
bond connection. Sorted Die Kits provide die sheets conveniently sorted into wavelength and radiant
flux bins. Cree's UB series chips are tested for conformity to optical and electrical specifications and
the ability to withstand 1000V ESD. These LEDs are useful in a broad range of applications such as
outdoor and indoor full motion LED video signs, transportation signaling and white LEDs, yet can also
be used in high volume applications such as LCD backlighting. Cree's UB series chips are compatible
with most radial and SMT LED assembly processes.

Notes:
1) Maximum ratings are package dependent. The above ratings were determined using a T-1 3/4 package (with Hysol OS4000 epoxy) for
characterization. Ratings for other packages may differ. The forward currents (DC and Peak) are not limited by the die but by the effect of the LED
junction temperature on the package. The junction temperature limit of 125C is a limit of the T-1 3/4 package; junction temperature should be
characterized in a specific package to determine limitations. Assembly processing temperature must not exceed 325C (< 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. The RAET procedure is performed on each die. The ESD
classification of Class II is based on sample testing according to MIL-STD 883E.

3)
All Products conform to the listed minimum and maximum specifications for electrical and optical characteristics, when assembled and operated at 20
mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given are within the range of average values
expected by the 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). Dominant wavelength measurements taken using Illuminance E.

4)
Caution: To obtain optimum output efficiency, the maximum height of die attach epoxy on the side of the chip should not exceed 80
m.

5)
Specifications are subject to change without notice.
