NICHIA STS-DA1-3160 <Cat.No.140521>
(1) Storage
● The products should be stored in an air tight container with desiccant (silica gel) at 30°C or less and 70% RH or less.
● To avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly.
● The LED incorporated in the product is silver plated. Customer is advised to store properly the products in controlled ambient
as exposure to a corrosive environment might cause the plated metal parts of the product to tarnish,
which might leads to adverse effects on optical characteristics.
(2) Handling Precautions
● Do not expose the product to shock. Failure to comply might affect on its characteristics.
(3) 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 wriststrap, ESD footwear, clothes, and floors
Grounded workstation equipment and tools
ESD table/shelf mat made of conductive materials
● 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.
● ESD damaged LEDs may have a current flow at a low voltage or no longer illuminate at a low current.
Failure Criteria: V_F<2.0V at I_F=0.5mA
(4) 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.
(5) Others
● This product is designed to be used for calibration. Do not use this product for any other purposes or other applications.
● 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.
● When a customer purchases this product, the customer and Nichia shall agree the official specification of the supplied products.
● Specifications and appearance subject to change for improvement without notice.
