Enhanced Compact Industry Standard PLCC-4/6 Package Provides High Contrast, a Wide Viewing Angle, Better Color Control and Reliability

Avago Technologies announced it has developed the industry’s first compact high-brightness water-resistant tricolor surface mount light-emitting diodes (LEDs) for use in indoor and outdoor full color signs and displays.  Avago’s ASMT-QTCO Plastic Leaded Chip Carrier (PLCC)-6 Blackbody and ASMT-YTBO industry standard PLCC- 4 LEDs have been enhanced to make them water-resistant.  As a result, a protection cover is not needed saving money for indoor and outdoor display designers.  These compact tricolor LEDs are ideal for use in electronic video screens and advertising signs used in transit malls, airports, and stadium scoreboards.  Avago is a leading supplier of analog interface components for communications, industrial and consumer applications.

Avago’s enhanced ASMT-YTBO LEDs provide full color display application designers with better color control and contrast, a 115-degree viewing angle and are specially designed to meet indoor and outdoor LED screen requirements for better screen resolution (greater than 12mm pixel size), and high-brightness performance.  They also have six leads to enable enhanced thermal management and individual color control of each chip to display a multitude of colors including white.  With dimensions of 4.4 mm by 4.4 mm by 3.5 mm, these LEDs from Avago also incorporate silicone material to extend light output performance over time.

The compact ASMT- QTCO package incorporates a separate heat path for each LED dice to enable it to be driven at higher currents. As a result, these SMT LEDs can operate in a wide range of environmental conditions to provide customers with high reliability.   Both tricolor LEDs are compatible with reflow soldering processes and have a moisture sensitivity level of 2a (MSL 2a) to make them ideal for use in SMT production environments.
