* 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.  
* Since the silicone used in the encapsulating resin is soft, do not press on the encapsulant resin.  
Pressure can cause nicks, chip-outs, encapsulant delamination and deformation, and wire breaks, decreasing reliability.  
* 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.  
* When using a pick and place machine, choose an appropriate nozzle for this product. Using a pick-and-place nozzle  
with a smaller diameter than the size of the LED's emitting surface will cause damage to the emitting surface  
and may also cause the LED not to illuminate.  
* The recommended soldering pad pattern is designed for attachment of the LED without problems.  
When precise mounting accuracy is required, such as high-density mounting, ensure that the size and shape of the pad  
are suitable for the circuit design.  
* Consider factors such as the reflow soldering temperature, hand soldering temperature, etc. when choosing the solder.  
* When flux is used, it should be a halogen free flux. Ensure that the manufacturing process is not designed in a manner  
where the flux will come in contact with the LEDs.  
* Make sure that there are no issues with the type and amount of solder that is being used.  
* All of the electrode pads are on the backside of this product; solder connections will not be able to be seen nor confirmed  
by a normal visual inspection. When using the product, ensure that there are no issues with the soldering conditions.

● 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.  
● Customer is advised to keep the LEDs in an airtight container when not in use. Exposure to a corrosive environment  
may cause the plated metal parts of the product to tarnish, which could adversely affect soldering and optical characteristics.  
It is also recommended to return the LEDs to the original moisture proof bags and reseal.  
● After assembly and during use, silver plating can be affected by the corrosive gases emitted by components and materials  
in close proximity of the LEDs within an end product, and the gases entering into the product from the external atmosphere.  
The above should be taken into consideration when designing.  
Resin materials, in particular, may contain substances which can affect silver plating, such as halogen.  
● 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.  
● Do not store the LEDs in a dusty environment.  
● Do not expose the LEDs to direct sunlight and/or an environment where the temperature is higher than  
normal room temperature.  
(2) Directions for Use  
● When designing a circuit, the current through each LED must not exceed the Absolute Maximum Rating.  
Operating at a constant current per LED is recommended. In case of operating at a constant voltage, Circuit B is recommended.  
If the LEDs are operated with constant voltage using Circuit A, the current through the LEDs may vary due to the variation  
in Forward Voltage characteristics of the LEDs.  
(A)  
(B)  
● This product should be operated using forward current. Ensure that the product is not subjected to  
either forward or reverse voltage while it is not in use. In particular, subjecting it to continuous reverse voltage  
may cause migration, which may cause damage to the LED die. When used in displays that are not used for a long time,  
the main power supply should be switched off for safety.  
● It is recommended to operate the LEDs at a current greater than 10% of the sorting current to stabilize the LED characteristics.  
● Ensure that excessive voltages such as lightning surges are not applied to the LEDs.  
● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage.

NICHIA STS-DA1-2713A <Cat.No.130328>  
(3) Handling Precautions  
● Do not handle the LEDs with bare hands as it will contaminate the LED surface and may affect the optical characteristics:  
it might cause the LED to be deformed and/or the wire to break, which will cause the LED not to illuminate.  
● 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.  
(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  
Grounded wrist strap, ESD footwear, clothes, and floors  
Grounded workstation equipment and tools  
ESD table/shelf mat made of conductive materials  
● Ensure that tools (e.g. soldering irons), jigs and machines that are being used are properly grounded and  
that proper grounding techniques are used in work areas. For devices/equipment that mount the LEDs,  
protection against surge voltages should also be used.  
● 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).  
● ESD damaged LEDs may have current flow at a low voltage or no longer illuminate at a low current.  
Failure Criteria: VF<4.0V at IF=0.5mA

NICHIA STS-DA1-2713A <Cat.No.130328>  
(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.  
● The following equations can be used to calculate the junction temperature of the products.  
1) TJ=TA+RθJA･W  
2) TJ=TS+RθJS･W  
*TJ=LED junction temperature: °C  
TA=Ambient temperature: °C  
TS=Soldering temperature (cathode side): °C  
RθJA=Thermal resistance from junction to ambient: °C/W  
RθJS=Thermal resistance from junction to TS measuring point: °C/W  
W=Input power(IF×VF): W  
Ts Point  
(7) Cleaning  
● The LEDs should not be cleaned with water, benzine, and/or thinner.  
● 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.  
● When dust and/or dirt adheres to the LEDs, soak a cloth with Isopropyl alcohol (IPA), then squeeze it before wiping the LEDs.  
● 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.
