- Automotive Cree® EZ900™ Gen II LEDs Data Sheet CxxxEZ900-Sxx000-2 Cree’s EZBright™ LEDs are the next generation of solid-state LED emitters that combine highly efficient InGaN materials with Cree’s proprietary optical design and device submount technology to deliver superior value for high- intensity LEDs. The optical design maximizes light extraction efficiency and enables a Lambertian radiation pattern. Additionally, these LEDs are die-attachable with conductive epoxy, solder paste or solder preforms, as well as the flux eutectic method. These vertically structured, low forward voltage LED chips are approximately 170 microns in height. Cree’s EZ™ chips are tested for conformity to optical and electrical specifications. These LEDs are useful in a broad range of applications such as general illumination, automotive lighting, and LCD backlighting. CxxxEZ900-Sxx000-2 Chip Diagram Dat a Sheet: CPR3DX Rev.

Maximum ratings are package-dependent. The above ratings were determined using a 3.45 x 3.45 mm SMT without an encapsulant for characterization. Ratings for other packages may differ. The junction temperature should be characterized in a specific package to determine limitations. Assembly processing temperature must not exceed 325°C (< 5 seconds). See Cree EZBright Applications Note for assembly-process information. 2. All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled and operated at 350 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 a Au-plated TO39 header without an encapsulant. Optical characteristics were measured in an integrating sphere using Illuminance E. 200 400 600 800 1000 1200 25 50 75 100 125 150 175 Maximum Forward Current (mA) Ambient Temperature (˚C) Rth j-a = 10 °C/W Rth j-a = 15 °C/W Rth j-a = 20 °C/W Rth j-a = 25 °C/W
