PLCC-4 Surface Mount Tricolor LED
Datasheet
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.
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.
