Small Half-Watt High-Brightness LEDs for Automotive Applications

Avago's 0.5W ASMC-QxB2-Txxx series of SMT LEDs are the latest addition to its family of Envisium(tm) Mid-Power LEDs. The target automotive applications for these new LEDs include rear combination lamps, center high-mounted stop lights (CHSML), tail lights, brake lights, side mirror turn-signal repeaters, and marker lamps for trucks and trailers. The high brightness output per LED and small package footprint (3.2 L by 2.8 W by 1.9 H mm) of the 0.5-W Envisium series provide the automotive lighting designer 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 0.5W Envisium Power PLCC-4 series provide two significant advantages in the automotive 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 0.5W 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 ASMC-QHB2-TCD0E (red-orange) and ASMC-QAB2-TAC0E (amber) Envisium LEDs feature typical luminous flux of 6.6 lumens and 9.3 lumens, respectively, at 150 mA drive currents.
