UltraThin™ Gen III LEDs
Data Sheet
CxxxUT190-Sxxxx-31
Cree’s UltraThin LEDs combine highly efficient InGaN materials with Cree’s proprietary G•SiC
®
substrate to deliver
superior price/performance for blue LEDs. These vertically structured LED chips are small in size and require a low
forward voltage. Cree’s UT™ series chips are tested for conformity to optical and electrical specifications and the
ability to withstand 1000 V ESD. Applications include keypad backlighting where sub-miniaturization and thinner
form factors are required.

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 125°C 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 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 minimum ESD ratings shown. The ESD classification of
Class 2 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 5 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). Optical characteristics measured in an
integrating sphere using Illuminance E.
4. Caution: To obtain optimum output efficiency, the amount of epoxy used should be characterized based upon the specific
application.

only one bin. Sorted die kit (CxxxUT190-Sxxxx-31) orders may be filled with any or all bins (CxxxUT190-xxxx-31)
contained in the kit. All radiant flux values are measured at If = 20 mA and all dominant wavelength values are
measured at If = 5 mA.
