● Recommended Soldering Pad Pattern
* 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.
* If the LEDs are reflowed a second time, it is recommended to perform the second soldering as soon as the LEDs have cooled down
to room temperature naturally after the first soldering in order to avoid moisture absorption.
* 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.
* When using a pick and place machine, choose an appropriate nozzle for this product.
* This product can differ in optical characteristics depending on both the number of reflow cycles and reflow temperature conditions.
In a single display, only LEDs with both the same number of reflow cycles and reflow temperature conditions
should be used regardless of the application type (e.g. rental and/or permanent installations).
* 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.

● 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.
● 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.
13
NICHIA STS-DA1-3207A <Cat.No.150528>
(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.
● 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.
● Care must be taken to ensure that the reverse voltage will not exceed the Absolute Maximum Rating
when using the LEDs with matrix drive.
● Ensure that excessive voltages such as lightning surges are not applied to the LEDs.
● Aging is recommended for detecting manufacturing and assembly defects. In particular, ensure that excessive current
and/or voltage is not applied to the LEDs. This aging should be conducted in environments where water condensation
does not occur.
● This product can be used in both indoor and outdoor applications; however, when the LEDs are used in the following environments,
incorporate sufficient measures into the display to prevent debris, water/moisture and gases
that will adversely affect the product.
- where water vapor is abundant
- where water condensation is likely to occur
- where water is likely to splash onto the LEDs
- where frost is likely to form on the surface of the LEDs (e.g. freezer, ice skating rink, etc.)
- where dust, dirt, debris, loose metallic materials and/or gases that will adversely affect the product are present
● When this product is used for displays that will be installed outside, the leads of the LEDs should be covered with silicone resin
to avoid exposure to outdoor environments. When silicone resin is filled up to the height of the 1-pin mark of the LED,
the LED lens will absorb less moisture. Choose a silicone resin that is sufficient to prevent water/moisture penetration
and salt damage.
● Reducing direct sunlight will be able to extend the life (Example: using a louver).
● The loss of luminous output due to sunlight can be minimized if the LEDs are used with louvers
and mounted in an orientation where the LED dice are vertically arranged in BGR order (Blue on top).
● In areas where hydrogen sulfide, which is a sulfide-based gas, is present (e.g. hot springs and volcanic areas),
and where salt is abundant (e.g. coastal areas), the life may be shortened.
● When power is applied for the first time after installation, the display should not be powered at 100% wattage
since the LEDs may have absorbed moisture. Before normal use of this display, operate the display at approximately 20% wattage
for an initial time period.
● If the display units will be rented, those units should be selected carefully to ensure that the display as a whole
will appear the same color and brightness.
● If the display units are loaded onto and/or transported by ship, the damp environment on the vessel will cause condensation;
the display units should be packaged to prevent moisture absorption.
● If a display that has been, or is being, used is relocated, it is possible that degradation of the LED has occurred.
When transporting this display, provide sufficient protection for the LEDs in addition to the moisture-proof packaging
for the display. When this display is reinstalled, ensure to follow the installation instructions for environments and use.
(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.
The lead could also cause an injury.
● 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.
14
NICHIA STS-DA1-3207A <Cat.No.150528>
(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).
● 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
● 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.
(9) Others
● 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.
● The specifications and appearance of this product may change without notice;
Nichia does not guarantee the contents of this specification. Both the customer and Nichia
will agree on the official specifications of supplied products before the volume production of a program begins.
