ASMT-UWB1-Nxxxx
OneWhite Surface Mount PLCC-2 LED Indicator
Data Sheet
Description
Features
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.
• High reliability package with silicone encapsulation
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.
• JEDEC MSL 3 product
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.
• Compatible with reflow soldering process
• High optical efficiency with 100 lm/W
• Available in 8 mm carrier tape with reel diameter
180mm
• ESD threshold of 1000 V (HBM model) per Jedec
Applications
• Non-automotive use
• General Signage backlighting
• Amusement machine backlighting
• Industrial lighting
• Light strips
CAUTION: LEDs are ESD sensitive. Please observe appropriate precautions during handling and processing.

PRECAUTIONARY NOTES
1. Handling precautions
2. Handling of moisture sensitive device
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. Special handling precautions need to be
observed during assembly of silicone encapsulated
LED products. Failure to comply might lead to damage
and premature failure of the LED. Do refer to Application Note AN5288, Silicone Encapsulation for LED: Advantages and Handling Precautions for more information.
a. Do not poke sharp objects into the silicone
encapsulant. Sharp object like tweezers or syringes
might apply excessive force or even pierce through
the silicone and induce failures to the LED die or
wire bond.
b. Do not touch the silicone encapsulant. Uncontrolled
force acting on the silicone encapsulant might result
in excessive stress on the wire bond. The LED should
only be held by the body.
c. Do no stack assembled PCBs together. Use an
appropriate rack to hold the PCBs.
d. Surface of silicone material attracts dusk and dirt
easier than epoxy due to its surface tackiness. To
remove foreign particles on the surface of silicone, a
cotton bud can be used with isopropyl alcohol (IPA).
During cleaning, rub the surface gently without
putting much pressure on the silicone. Ultrasonic
cleaning is not recommended.
e. For automated pick and place, Avago has tested
nozzle size below to be working fine 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, customer
is recommended to verify the nozzle selected will
not cause damage to the LED.
ID
Note: Diameter "ID" should
be bigger than 2.3mm
This product has a Moisture Sensitive Level 3 rating
per JEDEC J-STD-020. Refer to Avago Application Note
AN5305, Handling of Moisture Sensitive Surface Mount
Devices, for additional details and a review of proper
handling procedures.
a. Before use
