| RazerThin(R) LEDs CXXXRT230-S0200 Cree's RazerThin LEDs combine highly efficient InGaN materials with Cree's proprietary G*SiC(R) substrate to deliver superior price/performance for blue and green LEDs. These vertically structured LED chips are small in size and require a low forward voltage. Cree's RT 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.

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). 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 2 is based on sample testing according to MIL-STD-883E. 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 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. Caution: To obtain optimum output efficiency, the amount of epoxy used should be characterized based upon the specific application. Specifications are subject to change without notice.

A Standard Bins for CXXXRT230-S0200 LED chips are sorted to the radiant flux and dominant wavelength bins shown. Sorted die sheets contain die from only one bin. Sorted die kit (CXXXRT230-S0200) orders may be filled with any or all bins (CxxxRT230-0xxx) contained in the kit. All radiant flux values are measured at If = 20 mA and all dominant wavelength values are measured at If = 20 mA.
