SLR-56 Series
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, there’s high possibility to cause electro migration and result in
function failure.
2. Operation Life Span
There’s 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) 　
aterials.
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, there’s 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
Please concern the influence on LED in case of application with strong electromagnetic wave such as IH
(Induction heating).
