Data Sheet
Description
Features
The new Avago ALMD-Lx37 Oval LED series has the same
or just slightly less luminous intensity than conventional
high brightness through holes LEDs.
• Well defined spatial radiation pattern
The new Oval LED lamps can be assembled using common
SMT assembly processes and are compatible with industrial reflow soldering processes.
The LEDs are made with an advanced optical grade epoxy
for superior performance in outdoor sign applications.
The surface mount Oval LEDs are specifically designed for
full color / video signs and indoor or outdoor passenger
information sign applications.
• High brightness material
• Available in Red, Amber, Green and Blue color:
– Red AlInGaP 626 nm
– Amber AlInGaP 590 nm
– Green InGaN 525 nm
– Blue InGaN 470 nm
• JEDEC MSL 2A
• Compatible with reflow soldering process
• Tinted and diffused lens
For easy pick and place assembly, the LEDs are shipped
in tape and reel. Every reeled is shipped from a single
intensity and color bin except the red color for better uniformity.

CAUTION: InGaN devices are Class 1C HBM ESD sensitive, AlInGaP devices are Class 1B ESD sensitive per JEDEC Standard.
Please observe appropriate precautions during handling and processing. Refer to Application Note AN-1142 for additional details.
CAUTION: Customer is advised to always keep the LED in the moisture barrier bag with <5%RH when not in use as prolonged
exposure to environment might cause the leads to tarnish or rust, which might cause difficulties in soldering.

Notes:
1. The luminous intensity is measured on the mechanical axis of the lamp package and it is tested with pulsing condition.
2. The optical axis is closely aligned with the package mechanical axis.
3. Dominant wavelength, λd, is derived from the CIE Chromaticity Diagram and represents the color of the lamp.
4. θ½ is the off-axis angle where the luminous intensity is half the on-axis intensity.
5. Tolerance for each bin limit is ± 15%

Notes:
1. The dominant wavelength is derived from the chromaticity Diagram and represents the color of the lamp.
2. The radiant intensity, Ie in watts per steradian, may be found from the equation Ie = IV/hV where IV is the luminous intensity in candelas and hV is
the luminous efficacy in lumens/watt.
3. Indicates product final testing condition. Long term reverse bias is not recommended.

c. Do not apply any pressure or force on the LED during
reflow and after reflow when the LED is still hot.
d. It is preferred that you use reflow soldering to
solder the LED. Use hand soldering only for rework
if unavoidable but must be strictly controlled to the
following conditions:
- Soldering iron tip temperature = 320 °C max.
- Soldering duration = 3 sec max.
- Number of cycles = 1 only
- Power of soldering iron = 50 W max.
e. Do not touch the LED body with a hot soldering iron
except the soldering terminals as this may damage the
LED.
f. For de-soldering, it is recommended to use appropriate
double head soldering iron. User is advised to confirm
beforehand whether the functionality and performance
of the LED is affected by hand soldering.

PRECAUTIONARY NOTES
d. Control of assembled boards
1. Handling precautions
For automated pick and place, Avago has tested nozzle
size below made with urethane material 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.
Pick & Place nozzle
3.20
4.00
4.00
5.00
Note:
1. Nozzle tip should touch the LED flange during pick and place.
2. Outer dimensions of the nozzle should be able to fit into the
carrier tape pocket.
2. Handling of moisture-sensitive device
This product has a Moisture Sensitive Level 2a 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
- 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, then it is safe to reflow the
LEDs per the original MSL rating.
- It is recommended that the MBB not be opened
prior to assembly (e.g. for IQC).
b. Control after opening the MBB
- The humidity indicator card (HIC) shall be read
immediately upon opening of MBB.
- The LEDs must be kept at <30°C / 60%RH at all
times and all high temperature related processes
including soldering, curing or rework need to be
completed within 672 hours.
c. Control for unfinished reel
- Unused LEDs must be stored in a sealed MBB
with desiccant or desiccator at <5%RH.
11
e. Baking is required if:
- The HIC indicator is not BROWN at 10% and is
AZURE at 5%.
>2.2mm
LED flange
- If the PCB soldered with the LEDs is to be
subjected to other high temperature processes,
the PCB need to be stored in sealed MBB with
desiccant or desiccator at <5%RH to ensure that
all LEDs have not exceeded their floor life of 672
hours.
- The LEDs are exposed to condition of >30°C /
60% RH at any time.
- The LED floor life exceeded 672hrs.
The recommended baking condition is: 60±5ºC
for 20hrs. Baking should only be done once.
f. Storage
- The soldering terminals of these Avago LEDs
are silver plated. If the LEDs are being exposed
in ambient environment for too long, the silver
plating might be oxidized and thus affecting its
solderability performance. As such, unused LEDs
must be kept in sealed MBB with desiccant or in
desiccator at <5%RH.
3. Application precautions
a. Drive current of the LED must not exceed the
maximum allowable limit across temperature as
stated in the datasheet. Constant current driving is
recommended to ensure consistent performance.
b. LED is not intended for reverse bias. Do use other
appropriate components for such purpose. When
driving the LED in matrix form, it is crucial to ensure
that the reverse bias voltage is not exceeding the
allowable limit of the LED.
c. Avoid rapid change in ambient temperature
especially in high humidity environment as this will
cause condensation on the LED.
d. If the LED is intended to be used in outdoor or harsh
environment, the LED leads must be protected
with suitable potting material against damages
caused by rain water, oil, corrosive gases etc. It is
recommended to have louver or shade to reduce
direct sunlight on the LEDs.
4. Eye safety precautions
LEDs may pose optical hazards when in operation. It is
not advisable to view directly at operating LEDs as it
may be harmful to the eyes. For safety reasons, use appropriate shielding or personal protective equipments.
