* This LED is designed to be reflow soldered on to a PCB. If dip soldered, Nichia cannot guarantee its reliability.
* Reflow soldering must not be performed more than twice. Hand soldering must not be performed more than once.
* Avoid rapid cooling. Ramp down the temperature gradually from the peak temperature.
* Nitrogen reflow soldering is recommended. Air flow soldering conditions can cause optical degradation,
caused by heat and/or atmosphere.
* Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable,
a double-head soldering iron should be used.
It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.
* When soldering, do not apply stress to the LED while the LED is hot.
* This product can differ in optical characteristics depending on the number of reflow cycles.
In a single display, only LEDs with same number of reflow cycles should be used regardless of the application type,
such as rental and/or permanent installations.

Baking
● 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
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.
● After opening the moisture-proof aluminum bag, the products should go through the soldering process
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.
● After the “Period After Opening” storage time has been exceeded or silica gel desiccants are no longer blue,
the products should be baked. Baking should only be done once.
● The leads or electrode pads (anode and cathode) of the product are plated with silver. Exposure to a corrosive environment
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.
● Do not use sulfur-containing materials in commercial products. Some materials, such as seals and adhesives, may contain sulfur.
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.
● To prevent water condensation, please avoid large temperature and humidity fluctuations for the storage conditions.
(2) Directions for Use
● In designing a circuit, the current through each LED die must not exceed the Absolute Maximum Rating current
specified for each die.
It is recommended that each LED die is driven at a constant current.
● When having the two or more dice within this product on at the same time, the total power dissipation for the LED package
must be within the absolute maximum value specified in this specification.
● LEDs should be operated in forward bias. Driving circuits must not subject LEDs to either forward or reverse voltage while off.
Continuous reverse voltage can cause migration and LED damage.
● 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
when using the LEDs with matrix drive.
● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage.
(3) Handling Precautions
● Do not handle LEDs with bare hands, it may contaminate the LED surface and affect optical characteristics.
In the worst case, catastrophic failure from excess pressure through wire-bond breaks and package damage may result.
● When handling the product with tweezers, be careful not to apply excessive force to the resin.
Otherwise, The resin can be cut, chipped, delaminate or deformed, causing wire-bond breaks and catastrophic failures.
● 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,
delaminated and/or deformed. It may cause wire to break, leading to catastrophic failures.
13
NICHIA STS-DA1-1857C <Cat.No.120522>
(4) Design Consideration
● PCB warpage after mounting the products onto a PCB can cause the package to break.
The LED should be placed in a way to minimize the stress on the LEDs due to PCB bow and twist.
● The position and orientation of the LEDs affect how much mechanical stress is exerted on the LEDs placed near the score lines.
The LED should be placed in a way to minimize the stress on the LEDs due to board flexing.
● Board separation must be performed using special jigs, not using hands.
(5) Electrostatic Discharge (ESD)
● The products are sensitive to static electricity or surge voltage. ESD can damage a die and its reliability.
When handling the products, the following measures against electrostatic discharge are strongly recommended:
Eliminating the charge

● Proper grounding is required for all devices, equipment, and machinery used in product assembly.
Surge protection should be considered when designing of commercial products.
● If tools or equipment contain insulating materials such as glass or plastic,
the following measures against electrostatic discharge are strongly recommended:
Dissipating static charge with conductive materials
Preventing charge generation with moisture
Neutralizing the charge with ionizers
● The customer is advised to check if the LEDs are damaged by ESD
when performing the characteristics inspection of the LEDs in the application.
Damage can be detected with a forward voltage measurement or a light-up test at low current (≤1mA).
● LEDs with ESD-damaged dice (i.e. other than red) may have an increased leakage current, current flow at a low voltage,
or no longer illuminate at a low current.
Failure Criteria: VF<2.0V at IF=0.5mA
(6) Thermal Management
● Proper thermal management is an important when designing products with LEDs. LED die temperature is affected
by PCB thermal resistance and LED spacing on the board. Please design products in a way that the LED die temperature
does not exceed the maximum Junction Temperature (TJ).
● Drive current should be determined for the surrounding ambient temperature (TA) to dissipate the heat from the product.
(7) Cleaning
● If required, isopropyl alcohol (IPA) should be used. Other solvents may cause premature failure to the LEDs
due to the damage to the resin portion. The effects of such solvents should be verified prior to use.
In addition, the use of CFCs such as Freon is heavily regulated.
● Ultrasonic cleaning is not recommended since it may have adverse effects on the LEDs
depending on the ultrasonic power and how LED is assembled.
If ultrasonic cleaning must be used, the customer is advised to make sure the LEDs will not be damaged prior to cleaning.
(8) Eye Safety
● In 2006, the International Electrical Commission (IEC) published IEC 62471:2006 Photobiological safety of lamps
and lamp systems, which added LEDs in its scope.
On the other hand, the IEC 60825-1:2007 laser safety standard removed LEDs from its scope.
However, please be advised that some countries and regions have adopted standards
based on the IEC laser safety standard IEC 60825-1:20112001, which still includes LEDs in its scope.
Most of Nichia's LEDs can be classified as belonging into either the Exempt Group or Risk Group 1.
High-power LEDs, that emit light containing blue wavelengths, may be classified as Risk Group 2.
Please proceed with caution when viewing directly any LEDs driven at high current, or viewing LEDs
with optical instruments which may greatly increase the damages to your eyes.
● Viewing a flashing light may cause eye discomfort. When incorporating the LED into your product,
please be careful to avoid adverse effects on the human body caused by light stimulation.

● The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment,
communications equipment, measurement instruments and household appliances).
Consult Nichia's sales staff in advance for information on the applications in which exceptional quality
and reliability are required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or
health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor control system, automobiles,
traffic control equipment, life support systems and safety devices).
● The customer shall not reverse engineer by disassembling or analysis of the LEDs without having prior written consent
from Nichia. When defective LEDs are found, the customer shall inform Nichia directly before disassembling or analysis.
● Both the customers and Nichia will agree on official specifications of supplied products before a customer's volume production.
● Specifications and appearance subject to change for improvement without notice.
