Note : 1. Luminous intensity is measured with a light sensor and filter combination that approximates the
CIE eye-response curve.
2. Iv classification code is marked on each packing bag.
3. The chromaticity coordinates (x, y) is derived from the 1931 CIE chromaticity diagram.
4. Caution in ESD:
Static Electricity and surge damages the LED. It is recommend to use a wrist band or anti-electrostatic
glove when handling the LED. All devices, equipment and machinery must be properly grounded.
5. Tester
CAS140B is for the chromaticity coordinates (x, y) & Iv.
6. The chromaticity coordinates (x, y) guarantee should be added ± 0.01 tolerance.

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
The storage ambient for the LEDs should not exceed 30°C temperature or 60% relative humidity.
It is recommended that LEDs out of their original packaging are IR-reflowed within 672hrs.
For extended storage out of their original packaging, it is recommended that the LEDs be stored in a
sealed container with appropriate desiccant, or in a desiccators with nitrogen ambient.
LEDs stored out of their original packaging for more than 672hrs should be baked at about 60 deg C
for at least 20 hours before solder assembly.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.
4. Soldering

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.
Circuit model A
LED
Circuit model B
LED
(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:
Part
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.
