RazerThin® LEDs CxxxRT290-S0100 Cree’s RazerThin LEDs are a new generation of solid-state LED emitters that combine highly efficient InGaN materials with Cree’s proprietary G•SiC® substrate to deliver superior price/performance for high-intensity blue and green LEDs. These vertically structured LED chips are approximately 95 microns in height and require a low forward voltage. Cree’s RazerThin series chips have the ability to withstand 1000V ESD. Applications for RazerThin LEDs include next-generation 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. Seller makes no representations regarding ratings for packages other than the T-1 3/4 package used by Seller. The forward currents (DC and Peak) are not limited by the G•SiC 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). Product resistance to electrostatic discharge (ESD) is measured by simulating ESD using a rapid avalanche energy test (RAET). The RAET procedures are designed to approximate the maximum ESD ratings shown. Seller gives no other assurances regarding the ability of Products to withstand ESD. 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 the average values expected by Seller in large quantities and are provided for information only. Seller gives no assurances products shipped will exhibit such typical ratings. All measurements were made using lamps in T-1 3/4 packages (with Hysol OS4000 epoxy). Dominant wavelength measurements taken using Illuminance E. For reference only, typical Vf for C460, C470, and C527 is 3.2 V and at 20 mA. Copyright © 2003-2006 Cree, Inc. All rights reserved.
