● 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.

● Although the leads or electrode pads (anode and cathode) of the product are plated with gold, prolonged exposure to a corrosive

environment might cause the gold 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 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.
NVSU033C



● 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 product also emits visible light. If the LEDs are used as a light source in applications such as sensors, etc. take into

consideration the emission that is in the visible light spectrum.

● If this product is stored and/or used constantly under high humidity conditions, it may accelerate the deterioration of the die; this

may cause the radiant flux to decrease. If the LEDs are stored and/or used under these conditions, sufficient verification must be

done prior to use to ensure there are no issues for the chosen application.

● Do not design this LED into applications where condensation may occur. If the LEDs are stored/operated in these environments,

it may cause issues (e.g. current leaks that cause the radiant flux to decrease).


(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 glass. Otherwise, The glass 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 glass 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.

● If an aluminum PCB is used, customer is advised to verify the PCB with the products before use. Thermal stress during use can

cause the solder joints to crack.


(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, 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: V F <2.0V at I F =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 (T J ).

● Drive current should be determined for the surrounding ambient temperature (T A ) to dissipate the heat from the product.

● The following equations can be used to calculate the junction temperature of the products.

1) T J =T A +R θJA ・W 2) T J =T S +R θJS ・W

*T J =LED junction temperature: °C

T A =Ambient temperature: °C

T S =Soldering temperature (die heat sink): °C

R θJA =Thermal resistance from junction to ambient: °C/W

R θJS =Thermal resistance from junction to T S measurement point: °C/W

W=Input power(I F ×V F ): W

T S Measurement Point

U365nm


(7) Cleaning

● The LEDs should not be cleaned. Other cleaning agents except for Freon solvent should be tested prior to use whether they will

not affect the package and the glass. Please note that Freon solvent is prohibited worldwide.

● 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 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.

● Ensure that appropriate warning signs/labels are provided both on each of the systems/applications using the UV LEDs, in all

necessary documents (e.g. specification, manual, catalogs, etc.), and on the packaging materials.
