[Data Sheet]

■APPLICATION METHOD

１．Precaution for Drive System and Off Mode

　　　・Design the circuit without the electric load exceeding the ABSOLUTE MAXIMUM RATING that

　　　applies on the products.

　　　・If drive by constant voltage, it may cause current deviation of the LED and result in deviation of

　　　luminous intensity, so we recommend to drive by constant current. (Deviation of VF Value will

　　　cause deviation of current in LED.)

・Furthermore, for off mode, please do not apply voltage neither forward nor reverse. Especially,

for the products with the Ag-paste used in the die bonding, thereʼs high possibility to cause electro

migration and result in function failure.

２. Operation Life Span

　　　Thereʼs possibility for intensity of light drop according to working conditions and environments

　　　 (applied current, surrounding temperature and humidity, corrosive gases ), please call our Sales

　　　staffs for inquiries about the concerned application below.

　　　(1) Longtime intensity of light life

　　　(2) On mode all the time

３. Usage

　　　The Product is LED. We are not responsible for the usage as the diode such as Protection Chip,

Rectifier, Switching and so on.

■OTHERS

１. Surrounding Gas

　　　Notice that if it is stored under the condition of acid gas (chlorine gas, sulfured gas) or alkali gas

　　　 (ammonia), it may result in low soldering ability (caused by the change in quality of the plating

　　　surface ) or optical characteristics changes (light intensity, chrominance) and change in quality of

　　　die bonding (Ag-paste) materials. All of the above will cause function failure of the products.

　　　Therefore, please pay attention to the storage environment for mounted product (concern the

　　　generated gas of the surrounding parts of the products and the atmospheric environment).

２. Electrostatic Damage

　　　The product is part of semiconductor and electrostatic sensitive, thereʼs high possibility to be

　　　damaged by the electrostatic discharge.

　　　Please take appropriate measures to avoid the static electricity from human body and earthing

　　setting of production equipment. The resistance values of electrostatic discharge (actual values)

　　are different varies with products, therefore, please call our Sales staffs for inquiries.

３. Electromagnetic Wave

Applications with strong electromagnetic wave such as, IH cooker, will influence the reliability of LED,

therefore please evaluate before using it.
