(1) Storage
(2) Directions for Use
(3) Handling Precautions
● Product complies with JEDEC MSL 3 or equivalent. See IPC/JEDEC STD-020 for moisture-sensitivity details.
● Absorbed moisture in LED packages can vaporize and expand during soldering, which can cause interface delamination
● After opening the moisture-proof aluminum bag, the products should go through the soldering process
● After the “Period After Opening” storage time has been exceeded or silica gel desiccants are no longer blue,
● The leads or electrode pads (anode and cathode) of the product are plated with silver. Exposure to a corrosive environment
● Do not use sulfur-containing materials in commercial products. Some materials, such as seals and adhesives, may contain sulfur.
● To prevent water condensation, please avoid large temperature and humidity fluctuations for the storage conditions.
● In designing a circuit, the current through each LED die must not exceed the Absolute Maximum Rating current
● When having the two or more dice within this product on at the same time, the total power dissipation for the LED package
● LEDs should be operated in forward bias. Driving circuits must not subject LEDs to either forward or reverse voltage while off.
● For stabilizing the LED characteristics, it is recommended to operate at greater than 10% nominal current.
● Care must be taken to ensure that the reverse voltage will not exceed the Absolute Maximum Rating
● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage.
● Do not handle LEDs with bare hands, it may contaminate the LED surface and affect optical characteristics.
● When handling the product with tweezers, be careful not to apply excessive force to the resin.
● Dropping the product may cause damage.
● Do not stack assembled PCBs together. Failure to comply can cause the resin portion of the product to be cut, chipped,

and result in optical performance degradation. Products are packed in moisture-proof aluminum bags
to minimize moisture absorption during transportation and storage.
Included silica gel desiccants change from blue to red if moisture had penetrated bags.
within the range of the conditions stated above. Unused remaining LEDs should be stored with silica gel desiccants
in a hermetically sealed container, preferably the original moisture-proof bags for storage.
the products should be baked. Baking should only be done once.
might cause the silver plated the leads or electrode pads to tarnish, and thus leading to difficulties in soldering.
If unused LEDs remain, they must be stored in a hermetically sealed container.
Nichia recommends using the original moisture-proof bag for storage.
The extremely corroded or contaminated plating of LEDs might cause an open circuit. Silicone rubber is recommended
as a material for seals. Bear in mind, the use of silicones may lead to silicone contamination of electrical contacts
inside the products, caused by low molecular weight volatile siloxane.
specified for each die.
It is recommended that each LED die is driven at a constant current.
must be within the absolute maximum value specified in this specification.
Continuous reverse voltage can cause migration and LED damage.
when using the LEDs with matrix drive.
In the worst case, catastrophic failure from excess pressure through wire-bond breaks and package damage may result.
Otherwise, The resin can be cut, chipped, delaminate or deformed, causing wire-bond breaks and catastrophic failures.
