* Solder the LED no closer than 2 mm from the base of the lens. Soldering beyond the base of the tie bar is recommended.
* Dip soldering and manual soldering must only be done once.
* A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.
* Do not apply any stress to the lead particularly when heated.
* After soldering, the LED position must not be corrected.
* After soldering, NO mechanical shock or vibration should be applied to LED lens until the LEDs cool down
to room temperature.
* In order to avoid damage on the lens during cutting and clinching the leads, it is not recommended to solder
the LEDs directly on customer PCB without any gap between the lens and the board. If it is unavoidable,
customer is advised to check whether such soldering will not cause wire breakage or lens damage.
Direct soldering to double-sided PCBs must be avoided due to an increased effect of heat on the lens.
* 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.

CAUTIONS
(1) Lead Forming
● When forming leads, the leads should be bent at a point at lease 3mm from the base of the epoxy bulb.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 epoxy resin
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 desiccant (silica gel) to ensure
their shelf life will not exceed 1 year.
● Customer is advised to store properly the products in controlled ambient and complete immediately all high temperature
related process including soldering as exposure to corrosive environment might cause the plated metal parts of the product
to tarnish, which might lead to difficulties in soldering.
● To avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly.
(3) Directions for Use
● In designing a circuit, the current through each LED must not exceed the Absolute Maximum Rating specified for each LED.
It is recommended to use Circuit B which regulates the current flowing through each LED. In the meanwhile,
when driving LEDs with a constant voltage in 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 in forward bias. A driving circuit must be designed so that the product is not subjected to
either forward or reverse voltage while it is off. In particular, if a reverse voltage is continuously applied to the product,
such operation can cause migration resulting in LED damage.
● For stabilizing the LED characteristics, it is recommended to operate at 10% of the rated current or higher.
● 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.
(4) Handling Precautions
● When handling the product, do not touch it directly with bare hands as it may contaminate the surface and affect
on optical characteristics. In the worst cases, excessive force to the product might result in catastrophic failure due to
package damage and/or wire breakage.
● If the product is dropped, it might be damaged.
● 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, and wire to be broken, and thus resulting in catastrophic failure.
(5) Design Consideration
● PCB warpage after mounting the products onto a PCB can cause the package to brake.
The LEDs should be placed so as 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 LEDs should be placed so as to minimize the stress on the LEDs due to board flexing.
● Board separation must be performed using special jigs, not with hands.
13
NICHIA STS-DA1-1350 <Cat.No.110117>
(6) Electrostatic Discharge (ESD)
● The products are sensitive to static electricity or surge voltage. An ESD event may damage its die or reduce its reliability
performance. When handling the products, measures against electro static discharge, including the followings, are strongly
recommended.
Eliminating the charge;
Wrist strap, ESD footwear and garments, ESD floors
Grounding the equipment and tools at workstation
ESD table/shelf mat (conductive materials)
● Proper grounding techniques are required for all devices, equipment and machinery used in the assembly of the products.
Also note that surge protection should be considered in the design of customer products.
● If tools or equipment contain insulating materials, such as glass or plastic, proper measures against electro static discharge,
including the followings, are strongly recommended.
Dissipating the charge with conductive materials
Preventing the charge generation with moisture
Neutralizing the charge with ionizers
● When performing the characteristics inspection of the LEDs in your application, customer is advised to check on the LEDs
whether or not they are damaged by ESD. Such damage can be detected during forward voltage measurement
or lightup test at low current. (the recommended current is 1mA or lower)
● ESD-damaged LEDs may have an increased leakage current, current flow at low voltage, or no longer light up at low current.
Failure Criteria: VF<2.0V at IF=0.5mA
(7) Thermal Management
● Thermal management is an important factor when designing your product by using the LEDs. The rise in LED die temperature
can be affected by PCB thermal resistance or/and LED spacing as mounted on the board. Customer is advised to design
the product to ensure that the LED die temperature does not exceed the required maximum Junction Temperature (TJ).
● Drive current should be determined for the surrounding ambient temperature (TA) to dissipate the heat from the product.
(8) 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 for the LEDs since it may adversely effect on the LEDs by the ultrasonic power and
LED assembled condition. If it is unavoidable, customer is advised to check prior to use that the cleaning
will not damage the LEDs.
(9) Eye Safety
● The International Electrical Commission (IEC) published in 2006, IEC 62471:2006 Photobiological safety of lamps
and lamp systems which includes LEDs within its scope. Meanwhile LEDs were removed from the scope
of the IEC 60825-1:2007 laser safety standard, the 2001 edition of which included LED sources within its scope.
However, keep it mind that some countries and regions have adopted standards based on the IEC laser safety
standard IEC 60825-1:2001 which includes LEDs within its scope. Following IEC 62471:2006,
most of Nichia LEDs can be classified as belonging to either Exempt Group or Risk Group 1.
Especially a high-power LED, that emits light containing blue wavelengths, may be in Risk Group 2.
Great care should be taken when viewing directly the LED driven at high current or the LED with optical instruments,
which greatly increase the hazard to your eyes.
● Viewing a flashing light may cause eye discomfort. When incorporating the LED into your product,
precaution should be taken to avoid adverse effect on human body caused by the light stimulus.

NICHIA STS-DA1-1350 <Cat.No.110117>
(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.
● Customer and Nichia shall agree the official specification of supplied products prior to the start of a customer’s volume production.
● The appearance and specifications of the product may be modified for improvement without notice.
