Description
This family of SMT LEDs is packaged in the industry
standard PLCC-2 package. These SMT LEDs have high
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 as interior
signs application conditions.
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.
These LEDs are compatible with reflow soldering process.
The wide viewing angle at 120° makes these LEDs ideally
suited for panel, push button, office equipment, industrial
equipment, and home appliances. The flat top emitting
surface makes it easy for these LEDs to mate with light
pipes. With the built-in reflector pushing up the intensity of
the light output, these LEDs are also suitable to be used as
LED pixels in interior electronic signs.

Precautionary Notes
Handling Precautions
The encapsulation material of the LED is made of silicone
for better product reliability. Compared to epoxy
encapsulant that is hard and brittle, silicone is softer and
flexible. Observe special handling precautions during
assembly of silicone encapsulated LED products. Failure to
comply might lead to damage and premature failure of the
LED. Refer to Application Note AN5288, Silicone
Encapsulation for LED: Advantages and Handling
Precautions, for more information.
Do not poke sharp objects into the silicone encapsulant.
Sharp objects, such as tweezers or syringes, might
apply excessive force or even pierce through the
silicone and induce failures to the LED die or wire bond.
Do not touch the silicone encapsulant. Uncontrolled
force acting on the silicone encapsulant might result in
excessive stress on the wire bond. Hold the LED only
by the body.
Do not stack assembled PCBs together. Use an
appropriate rack to hold the PCBs.
The surface of the silicone material attracts dust and
dirt easier than epoxy due to its surface tackiness. To
remove foreign particles on the surface of silicone, use
a cotton bud with isopropyl alcohol (IPA). During
cleaning, rub the surface gently without putting much
pressure on the silicone. Utrasonic cleaning is not
recommended.
For automated pick and place, Broadcom has tested
the following nozzle size to work well with this LED.
However, due to the possibility of variations in other
parameters, such as pick and place, machine maker/
model and other settings of the machine, verify that the
selected nozzle will not cause damage to the LED.
Handling Moisture-Sensitive Devices
This product has a Moisture Sensitive Level 3 rating per
JEDEC J-STD-020. Refer to Broadcom Application Note
AN5305, Handling of Moisture Sensitive Surface Mount
Devices, for additional details and a review of proper
handling procedures.
Before use
– An unopened 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 humidity
indicator card (HIC) indicates that baking is not
required, it is safe to reflow the LEDs per the original
MSL rating.
– Do not open the MBB prior to assembly (for
example, for IQC).
Control after opening the MBB:
– Read the HIC immediately upon opening the MBB.
– Keep the LEDs at < 30°C / 60% RH at all times and
all high temperature-related processes, including
soldering, curing, or rework, must be completed
within 168 hours.
Control for unfinished reel:
Store unused LEDs in a sealed MBB with desiccant or
desiccator at <5% RH.
Control of assembled boards:
If the PCB soldered with the LEDs is to be subjected to
other high-temperature processes, store the PCB in a
sealed MBB with desiccant or desiccator at <5% RH to
ensure that all LEDs have not exceeded their floor life of
168 hours.
Baking is required if the following conditions exist:
– The HIC indicator is not BROWN at 10% and is
AZURE at 5%.
– The LEDs are exposed to condition of > 30°C / 60%
RH at any time.
– The LED floor life exceeded 168 hours.
The recommended baking condition is: 60°C ± 5ºC for
20 hours.
Baking should only be done once.
Storage:
The soldering terminals of these Broadcom LEDs are
silver plated. If the LEDs are exposed in an ambient
environment for too long, the silver plating might be
oxidized, thus affecting its solderability performance. As
such, keep unused LEDs in a sealed MBB with
desiccant or in desiccator at <5% RH.

Application Precautions
The drive current of the LED must not exceed the
maximum allowable limit across temperature as stated
in the data sheet. Constant current driving is
recommended to ensure consistent performance.
LEDs exhibit slightly different characteristics at different
drive currents that might result in larger variations in
their performance (that is, intensity, wavelength, and
forward voltage). Set the application current as close as
possible to the test current to minimize these variations.
The LED is not intended for reverse bias. Use other
appropriate components for such purposes. When
driving the LED in matrix form, ensure that the reverse
bias voltage does not exceed the allowable limit of the
LED.
Do not use the LED in the vicinity of material with sulfur
content, in environments of high gaseous sulfur
compounds and corrosive elements. Examples of
materials that may contain sulfur are rubber gaskets,
RTV (room temperature vulcanizing) silicone rubber,
rubber gloves, and so on. Prolonged exposure to such
environments may affect the optical characteristics and
product life.
Avoid rapid change in ambient temperature, especially
in high-humidity environments, because this will cause
condensation on the LED.
Although the LED is rated as IPx6 according to
IEC60529: Degree of protection provided by enclosure,
the test condition may not represent actual exposure
during application. If the LED is intended to be used in
outdoor or harsh environments, the LED must be
protected against damages caused by rain water, dust,
oil, corrosive gases, external mechanical stress, and so on
.
Thermal Management
Optical, electrical, and reliability characteristics of LED are
affected by temperature. The junction temperature (TJ) of
the LED must be kept below allowable limit at all times. TJ
can be calculated as follows:
TJ = TA + RθJ-A × IF × VFmax
where;
TA = ambient temperature (°C)
RθJ-A = thermal resistance from LED junction to ambient
(°C/W)
IF = forward current (A)
VFmax = maximum forward voltage (V)
The complication of using this formula lies in TA and RθJ-A.
Actual TA is sometimes subjective and hard to determine.
RθJ-A varies from system to system depending on design
and is usually not known.
Another way of calculating TJ is by using solder point
temperature TS as follows:
TJ = TS + RθJ-S × IF × VFmax
where;
TS = LED solder point temperature as shown in the
following figure (°C)
RθJ-S = Thermal resistance from junction to solder point
(°C/W)
TS can be measured easily by mounting a thermocouple on
the soldering joint as shown in the preceding figure, while
RθJ-S is provided in the data sheet. Verify the TS of the LED
in the final product to ensure that the LEDs are operated
within all maximum ratings stated in the data sheet.
Eye Safety Precautions
LEDs may pose optical hazards when in operation. Do not
look directly at operating LEDs because it may be harmful
to the eyes. For safety reasons, use appropriate shielding or
personal protective equipment.
