TR5050™ LEDs CxxxTR5050-Sxx000 Data Sheet Cree’s TR5050 LEDs are the next generation of solid-state LED emitters that combine highly efficient InGaN materials with Cree’s proprietary device technology and silicon-carbide substrates to deliver superior value for the TV-backlighting and general-illumination markets. The TR5050 LEDs are among the brightest in the top-view market while delivering a low forward voltage, resulting in a very bright and highly efficient solution. The design is optimally suited for industrystandard top-view packages. FEATURES APPLICATIONS • • Rectangular LED RF Performance – 450 & 460 nm – 180 mW min Large LCD Backlighting – Television • Adhesive Die Attach • General Illumination • Low Forward Voltage – 3.3 V Typical at 120 mA • Medium LCD Backlighting • Maximum DC Forward Current - 180 mA – Portable PCs • Class 2 ESD Rating – Monitors • InGaN Junction on Thermally Conductive SiC • LED Video Displays Substrate • White LEDs CxxxTR5050-Sxx000 Chip Diagram .CPR3ER Rev Data Sheet: Top View Die Cross Section Bottom View TR5050 LED 500 x 500 μm Cathode (-) 98-μm diameter Anode (+) 90-μm diameter Bottom Surface 327 x 327 μm t = 175 μm Subject to change without notice. www.cree.com 1 Maximum Ratings at TA = 25°C Notes 1&3 DC Forward Current CxxxTR5050-Sxx000 180 mA Note 4 Peak Forward Current (1/10 duty cycle @ 1 kHz) 230 mA LED Junction Temperature 150°C Reverse Voltage 5V Operating Temperature Range -40°C to +100°C Storage Temperature Range Electrostatic Discharge Threshold (HBM) -40°C to +100°C 1000 V Note 2 Electrostatic Discharge Classification (MIL-STD-883E) Class 2 Note 2 Typical Electrical/Optical Characteristics at TA = 25°C, If = 120 mA Part Number Forward Voltage (Vf, V) Note 3 Reverse Current [I(Vr=5V), μA] Full Width Half Max (λD, nm) Min.

Maximum ratings are package-dependent. The above ratings were determined using lamps in chip-on-MCPCB (metal core PCB) packages for characterization. Ratings for other packages may differ. 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 maximum ESD ratings shown. 3. All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled and operated at 120 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 encapsulant and clear epoxy die attach). Optical characteristics measured in an integrating sphere using Illuminance E. 4. The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is crucial for the end-product to be designed in a manner that minimizes the thermal resistance from the LED junction to ambient in order to optimize product performance.
