Compact Power PLCC-4 Surface-Mount LEDs Ideal for Use in Automotive, Electronic Sign and Signals, Industrial and Consumer Applications

SAN JOSE, Calif., May 08, 2007

Avago Technologies today introduced the industry’s first half-watt (0.5-W) high-brightness light-emitting diodes (LED) in an industry-standard PLCC-4 surface-mount (SMT) package. These new 0.5-W Power LEDs, which are available in white, amber, red-orange and red colors, feature the industry’s smallest package size, a wide 120-degree viewing angle, and are optimized for long operating life under severe environmental conditions. Moreover, these new high-brightness LEDs were designed to dissipate heat more efficiently to provide superior thermal management and consistent light output. Avago’s new 0.5-W LEDs are ideal for use by designers of automotive interior and exterior lighting, electronic sign and signals (ESS), office automation, home appliances and industrial equipment. Avago is a leading supplier of analog interface components for communications, industrial and consumer applications.

Avago’s 0.5-W ASMT-QWB2 (white) and ASMT-QxB2 (amber, red-orange and red) series of SMT LEDs can be used for backlighting dashboards, dome and map lighting, puddle lamps, rear reverse lamp indicator lighting and license plate illumination in automotive applications. These LEDs can also be used for decorative lighting in general lighting applications, channel lettering in ESS applications, and for backlighting instrument panels and displays in industrial equipment, office automation and home appliance applications. Moreover, the high brightness output per LED and small package footprint (3.2 L by 2.8 W by 1.9 H mm) of Avago’s 0.5-W high-brightness Power LED series provide lighting designers with greater flexibility in designing the size, shape and appearance of lighting assemblies.

In addition to the combination of high-brightness, long life and compact size, Avago’s 0.5-W Power PLCC-4 series of LEDs provide two significant advantages in the production environment: They can be easily soldered using conventional surface mount techniques to minimize production costs, and the package is qualified to a Joint Electron Device Engineering Council (JEDEC) moisture sensitive level (MSL) rating of 2A. For manufacturers, this rating means that the 0.5-W Power PLCC-4 LEDs can be kept in the open air (30° C, 60 percent relative humidity) for up to four weeks after being removed from its sealed package without the need to remove absorbed moisture.

Avago’s ASMT-QWB2 and ASMT-QxB2 0.5-W LEDs feature typical luminous flux of 9.8 to 17 lumens at 150 mA drive currents. The colors and corresponding part numbers for these new high-brightness SMT Power LEDs are: White (ASMT-QWB2), Amber (ASMT-QAB2), Red-Orange (ASMT-QHB2), and Red (ASMT-QRB2). Other features include:

* High optical efficiency: 30 lm/W
* High junction temperature of 125 degrees C
* Low thermal resistance: 60 degrees C/W junction to pin Long Life feature:
- IV degrades < 50 percent over 50,000 hours at 25 deg C
- IV degrades < 50 percent over 5,000 hours at 85 deg C
* Standard PLCC-4 package
* Available in 12 mm tape on 8-inch (180 mm) diameter reels for automated assembly
* Operating temperature range: –40° C to 110°
* Pb-Free and RoHS compliant

U.S. Pricing and Availability

Avago’s 0.5-W Power LEDs are priced from $0.53 to $0.73 each depending on quantity. Samples and production quantities are available now through Avago’s direct sales channel and worldwide distribution partners.
