Data Sheet

Precautionary Notes

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.

NOTE

a. Nozzle tip should touch the LED flange during pick

and place.

b. Outer dimensions of the nozzle should be able to fit

into the carrier tape pocket.

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.

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).

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.

Control for unfinished reel



Unused LEDs must be stored 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,

the PCB must 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.

Baking is required if:



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 672 hrs.

The recommended baking condition is: 60 °C ±5 ºC for

20 hrs. Baking should only be done once.

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.

Application precautions

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 do exhibit slightly different characteristics at

different drive currents that might result in larger

performance variations (i.e., intensity, wavelength,

and forward voltage). The user is recommended to set

the application current as close as possible to the test

current to minimize these variations.

The LED is not intended for reverse bias. Do use other

appropriate components for such purposes. When

driving the LED in matrix form, it is crucial to ensure

that the reverse bias voltage does not exceed the

allowable limit of the LED.

Avoid rapid change in ambient temperature,

especially in high humidity environments, because

this will cause condensation on the LED.

If the LED is intended to be used in outdoor or harsh

environments, 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.
