XBright® Power Chip LED CxxxXB500-Sxx00-A Cree’s XB™ power chip series of LEDs are the next 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 LEDs. These LED chips have a geometrically enhanced Epi-down design to maximize light extraction efficiency and require only a single wire bond connection. These LEDs are useful in a broad range of applications such as outdoor full-motion LED video signs, automotive lighting and white LEDs. Cree’s XB power chips are compatible with optical power packages that employ proper thermal management.

Maximum ratings are package dependent. The above ratings were determined using a Au-plated TO39 header 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). All Products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled and operated at 125 mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given are within the range of average expected by 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 measured in an integrating sphere using Illuminance E. 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. Back contact metal is 80%/20% Au/Sn by weight, with target eutectic melting temperature of approximately 282°C. Caution: To avoid leakage currents and achieve maximum output efficiency, die attach material must not contact the side of the chip. XB500™ chips are shipped with the junction side up, requiring die transfer prior to die attach. Specifications are subject to change without notice. Copyright © 2005-2006 Cree, Inc.
