* Solder the LED no closer than 3mm from the base of the lead.
* Dip soldering/hand soldering must not be performed more than once.
* Care should be taken to avoid cooling at a rapid rate and ensure the peak temperature ramps down slowly.
* When soldering, do not apply stress to the lead frame while the LED is hot.
* When using a pick and place machine, choose an appropriate nozzle for this product.
* After soldering, the LED position must not be corrected.
* After soldering, NO mechanical shock or vibration should be applied to LED cap
until the LEDs cool down to room temperature.
* In order to avoid damage on the cap during cutting and clinching the leads,
it is not recommended to solder the LEDs directly on customer PCB without any gap between the cap and the board.
If it is unavoidable, customer is advised to check whether such soldering will not cause wire breakage or cap damage.
Direct soldering to double-sided PCBs must be avoided due to an increased effect of heat on the cap.
* When it is necessary to clamp the LEDs to prevent soldering failure,
it is important to minimize the mechanical stress on the LEDs.
* Cut the LED lead frames at room temperature. Cutting the lead frames at high temperature may cause failure of the LEDs.
* Consider factors such as the dip 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.

CAUTIONS
(1) Lead Forming
● When forming leads, the leads should be bent at a point at lease 3mm from the base of the lead.
Do not use the base of the leadframe as a fulcrum during lead forming.
● Lead forming should be done before soldering.
● Do not apply any bending stress to the base of the lead.
The stress to the base may damage the LED's characteristics or it may break the LEDs.
● When mounting the product onto a printed circuit board, the via-holes on the board should be exactly aligned
with the lead pitch of the product. If the LEDs are mounted with stress at the leads, it causes deterioration of the cap
and this will degrade the LEDs.
(2) Storage
● Shelf life of the products in unopened bag is 3 months(max.) at <30°C and 70% RH from the delivery date.
If the shelf life exceeds 3 months or more, the LEDs need to be stored in a sealed container
with silica gel desiccants to ensure their shelf life will not exceed 1 year.
● Nichia LED leadframe are gold plated iron alloy. This gold surface may be affected by environments
which contain corrosive substances. Please avoid conditions which may cause the LED to corrode, tarnish or discolor.
This corrosion or discoloration may cause difficulty during soldering operation.
It is recommended that the LEDs be used as soon as possible.
● To avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly.
● 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.
(3) 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.
● This LED also emits visible light. Please take notice of visible light spectrum,
in case you use this LED as light source of sensors etc.
(4) 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.
● Dropping the product may cause damage.
● Do not stack assembled PCBs together. Failure to comply can cause the cap portion of the product to be cut, chipped,
delaminated and/or deformed. It may cause wire to break, leading to catastrophic failures.
12
NICHIA STS-DA1-2749C <Cat.No.131107>
(5) 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.
(6) 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 at low current (≤1mA).
● ESD damaged LEDs may have current flow at a low voltage.
Failure Criteria: VF<2.0V at IF=0.5mA
(7) 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.
(8) 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.

NICHIA STS-DA1-2749C <Cat.No.131107>
(9) 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 products are UV light LEDs, and radiate intense UV light during operation. Since UV light can be harmful to eyes,
do NOT look directly into the UV light, even through an optical instrument. In case of the light reflection,
UV protective glasses are required to use in order to avoid damage by the light.
(10) 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.
