NOTE: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
2.θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single
wavelength which defines the color of the device.
4. Forward Voltage Tolerance is +/- 0.1 volt.

CAUTIONS
1. Application
The LEDs described here are intended to be used for ordinary electronic equipment (such as office
equipment, communication equipment and household applications).Consult Liteon’s Sales in advance
for information on applications in which exceptional reliability is required, particularly when the failure
or malfunction of the LEDs may directly jeopardize life or health (such as in aviation, transportation,
traffic control equipment, medical and life support systems and safety devices).
2. Storage
This product is qualified as Moisture sensitive Level 3 per JEDEC J-STD-020 Precaution when handing
this moisture sensitive product is important to ensure the reliability of the product.
The package is sealed:
The LEDs should be stored at 30°C or less and 90%RH or less. And the LEDs are limited to use
within one year, while the LEDs is packed in moisture-proof package with the desiccants inside.
The package is opened:
The LEDs should be stored at 30°C or less and 60%RH or less. Moreover, the LEDs are limited to
solder process within 168hrs. If the Humidity Indicator shows the pink color in 10% even higher or
exceed the storage limiting time since opened, that we recommended to baking LEDs at 60°C at least
48hrs. To seal the remainder LEDs return to package, it’s recommended to be with workable
desiccants in original package.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.

5. Drive Method
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs
connected in parallel in an application, it is recommended that a current limiting resistor be incorporated
in the drive circuit, in series with each LED as shown in Circuit A below.

(A) Recommended circuit.
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics
of those LEDs.

6. ESD (Electrostatic Discharge)
Static Electricity or power surge will damage the LED.
Suggestions to prevent ESD damage:
Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs.
All devices, equipment, and machinery must be properly grounded.
Work tables, storage racks, etc. should be properly grounded.
Use ion blower to neutralize the static charge which might have built up on surface of the LED’s
plastic lens as a result of friction between LEDs during storage and handling.
ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low
forward voltage, or “ no lightup ” at low currents.
To verify for ESD damage, check for “ lightup ” and Vf of the suspect LEDs at low currents.
The Vf of “ good ” LEDs should be >[email protected] for InGaN product and >[email protected] for AlInGaP
product.
