• This product is sensitive to electrostatic and care must be fully taken when handling products. Particularly
in the case that an overvoltage shall be applied, the overflowed energy may cause damage to or possibly
result in destruction of the product. Users shall take absolutely secure countermeasures against
electrostatic and surge when handling the product.
• A damage to the device might create a tiny leakage path, which causes the LED lamp not to light up in the
low-current region or causes a drop in the V
F
rise voltage.
Failure criterion: I
F
≥ 0.5 mA @ V
F
= 2 V
• If multiple LEDs are connected in parallel, they will experience variations in the forward current due to
the characteristics differences in forward voltage. Ensure that the forward current of all the LEDs fall
within the intended range of the system design, for example, by inserting current-limiting resistors to each
LED string.
• Since this product is intended to be used for display lighting, the measurement standard is based on the
spectral sensitivity of the human eye. It is not intended to be used for any applications other than display
lighting (e.g., sensors and light communications systems.)
• Generally, GaN-based LEDs exhibit instability or significant device-to-device variations in the relative
luminous flux in the low-current region. To avoid these problems, an application system should be
designed in such a manner that the GaN-based LEDs are driven with a forward current of 10 mA or
higher.
• This device should not be reverse-biased.
• When the device is used in places that are likely to be exposed to condensation, salt or corrosive gas, the
effect on its performance and reliability must be thoroughly verified.
• Please note the handling of products during evaluation.
(1) Please do not apply pressure to the upper surface of the product with finger, tweezers, and others.
Failure of product to light up may occur due to package deformation, wire deformation and/or
disconnection.
(2) Should tweezers be used in product handling, one with flat surfaces is recommended.
(3) Please handle the product widthwise.
(4) Please do not drop the product. There is a possibility for package transformation etc. to occur when the
product is dropped.
(5) Please do not stack the printed circuit boards on which the product is mounted to prevent damages to
product surface. Also, please note not to damage the surface of the product with cushioning material
etc. Surface damage to the product may influence their optical characteristics.
(6) Solder, flux, paper or heat-sensitive materials that might be deformed or discolored at
high temperatures should not be left on the surface of an LED lamp.
• Extreme care should be exercised when using this device for high-power applications:
(1) Do not directly touch this device during active operation because it becomes hot,
depending on the operating power.
(2) Take a possible rise in ambient temperature around this device and the heat-resistant temperature of
the system components into consideration.
