ASMT‐SxB4‐Pxxxx
Surface Mount LED Indicator
Datasheet
Description
Avago Power PLCC‐4 SMT LEDs are high performance
SMT LEDs targeted mainly in Electronic Sign and
Signals (ESS) markets. The package can be driven at
higher current due to its superior package design. The
product is able to dissipate heat more efficiently
compared to the conventional PLCC‐2 SMT LEDs. In
proportion to the increase in driving current, this
family of LEDs is able to produce higher light output
compared to the conventional PLCC‐2 SMT LEDs.
These SMT LEDs have higher reliability and better
performance and are designed to work under a wide
range of environmental conditions. This higher
reliability makes them suitable to be used in
electronic signs and signals.
To facilitate easy pick and place assembly, the LEDs
are packed in EIA‐compliant tape and reel. Every reel
will be shipped in single intensity and color bin
(except for red color), to provide close uniformity.
These LEDs are compatible with IR solder reflow
process.
