ASMT-SxB4-Zxxxx
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.

Handling Precaution
The en
capsulation material of the product is made of
silicone for better reliability of the product. As silicone is a
soft material, please do not press on the silicone or poke a
sharp object onto the silicone. These might damage the
product and cause premature failure. During assembly or
handling, the unit should be held on the body only. Please
refer to Avago Application Note AN 5288 for detail
information.
Moisture Sensitivity
This product is qualified as Moisture Sensitive Level 3 per
Jedec J-STD-020. Precautions when handling this moisture
sensitive product is important to ensure the reliability of
the product. Do refer to Avago Application Note AN5305
Handling of Moisture Sensitive Surface Mount Devices for
details.
A. Storage before use
• Unopen moisture barrier bag (MBB) can be stored
at <40°C/90%RH for 12 months. If the actual shelf
life has exceeded 12 months and the HIC indicates
that baking is not required, then it is safe to reflow
the LEDs per the original MSL rating.
• It is not recommended to open the MBB prior to
assembly (e.g. for IQC).
B. Control after opening the MBB
• The humidity indicator card (HIC) shall be read im-
mediately upon opening of MBB.
•
The LEDs must be kept at <30°C / 60%RH at all
time and all high temperature related process
including
soldering, curing or rework need to be
completed within 168 hours.
C. Control for unfinished reel
•
For any unuse LEDs, they need to be stored in
sealed MBB with desiccant or desiccator at <5%RH.
D. Control of assembled boards
• If the PCB soldered with th
e LEDs is to be
subjected to other high temperature processes,
the PCB need to be stored in sealed MBB with
desiccant or desic
cator at <5%RH to ensure no
LEDs have exceeded their floor life of 168 hours.
E. Baking is required if:
• “10%” is Not Green and “5%” HIC indicator turns
Azure.
• The LEDs are exposed to condition of >30°C / 60%
RH at any time.
• The LEDs floor life exceeded 168 hours.
Recommended baking condition: 60±5°C for 20 hours.
