| ASMT-QTB0-0xxxx PLCC-4 Surface Mount Tricolor LED Data Sheet Description This family of SMT LEDs is packaged in the industry standard PLCC-4 package with additional heat sinking capability enabling it to be driven at even higher current. These SMT LEDs have high brightness and reliability performance and are designed to work under a wide range of environmental conditions. This high reliability feature makes them ideally suited to be used under exterior and interior full color signs application conditions. To facilitate easy pick & place assembly, the LEDs are packed in EIA-compliant tape and reel. Every reel will be shipped in single intensity and color bin; except red color to provide close uniformity. These LEDs are compatible with reflow soldering process. This super wide viewing angle at 120 together with the built in reflector pushing up the intensity of the light output makes these LED suitable to be used in the interior electronics signs. The black top surface of the LED provides better contrast enhancement especially in the full color sign application. Features * Industry Standard PLCC-4 package (Plastic Leaded Chip Carrier) with additional heat sinking capability * High reliability LED package with silicone encapsulation * High brightness using AlInGaP and InGaN dice technologies * Wide viewing angle at 120 * Compatible with reflow soldering process * JEDEC MSL 2a Applications * Indoor and outdoor full color display CAUTION: LEDs are Class 1C ESD sensitive. Please observe appropriate precautions during handling and processing. Please refer to Avago Application Note AN-1142 for additional details.

As silicone is a soft material, please do not press on the silicone or poke a sharp object onto the silicone. These might damage the product and cause premature failure. During assembly of handling, the unit should be held on the body only. Please refer to Avago Application Note AN 5288 for detail information. B. Control after opening the MBB * The humidity indicator card (HIC) shall be read immediately upon opening of MBB. * The LEDs must be kept at <30C / 60%RH at all time and all high temperature related process including soldering, curing or rework need to be completed within 672 hours. C. Control for unfinished reel * For any unuse LEDs, they need to be stored in sealed MBB with desiccant or desiccator at <5%RH. Moisture Sensitivity This product is qualified as Moisture Sensitive Level 2a per Jedec J-STD-020. Precautions when handling this moisture sensitive product is important to ensure the reliability of the product. Do refer to Avago Application Note AN5305 Handling of Moisture Sensitive Surface Mount Devices for details. D. Control of assembled boards * If the PCB soldered with the LEDs is to be subjected to other high temperature processes, the PCB need to be stored in sealed MBB with desiccant or desiccator at <5%RH to ensure no LEDs have exceeded their floor life of 672 hours A. Storage before use * Unopen moisture barrier bag (MBB) can be stored at <40C/90%RH for 12 months. If the actual shelf life has exceeded 12 months and the HIC indicates that baking is not required, then it is safe to reflow the LEDs per the original MSL rating. * It is not recommended to open the MBB prior to assembly (e.g. for IQC). E. Baking is required if: * "10%" or "15%" HIC indicator turns pink * The LEDs are exposed to condition of >30C / 60% RH at any time. * The Led floor life exceeded 672hrs. Recommended baking condition: 605C for 20hrs For product information and a complete list of distributors, please go to our web site: www.avagotech.com Avago, Avago Technologies, and the A logo are trademarks of Avago Technologies Limited in the United States and other countries.
