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 70% relative humidity.
It is recommended that LEDs out of their original packaging are used within three months.
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 desiccators with nitrogen ambient.
3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LEDs if necessary.
4. Lead Forming & Assembly
During lead forming, the leads should be bent at a point at least 3mm from the base of LED lens.
Do not use the base of the leadframe as a fulcrum during forming.
Lead forming must be done before soldering, at normal temperature.
During assembly on PCB, use minimum clinch force possible to avoid excessive mechanical stress.
5. Soldering
When soldering, leave a minimum of 2mm clearance from the base of the lens to the soldering point.
Dipping the lens into the solder must be avoided.
Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.
Recommended soldering conditions :
Soldering iron

100°C Max.

300°C Max.
Pre-heat
Soldering time

Note: Excessive soldering temperature and/or time might result in deformation of the LED lens or
catastrophic failure of the LED. IR reflow is not suitable process for through hole type LED lamp
product.

6. 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
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
7. ESD (Electrostatic Discharge)
Static Electricity or power surge will damage the LED.
Suggestions to prevent ESD damage:
Use 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 LEDs
plastic lens as a result of friction between LEDs during storage and handing
ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low
forward voltage, or “no light up” at low currents. To verify for ESD damage, check for “light up” and
Vf of the suspect LEDs at low currents.
The Vf of “good” LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP product.

Suggested checking list :
Training and Certification
1. Everyone working in a static-safe area is ESD-certified?
2. Training records kept and re-certification dates monitored?
Static-Safe Workstation & Work Areas
1. Static-safe workstation or work-areas have ESD signs?
2. All surfaces and objects at all static-safe workstation and within 1 ft measure less than 100V?
3. All ionizer activated, positioned towards the units?
4. Each work surface mats grounding is good?
Personnel Grounding
1. Every person (including visitors) handling ESD sensitive (ESDS) items wear wrist strap, heel strap or
conductive shoes with conductive flooring?
2. If conductive footwear used, conductive flooring also present where operator stand or walk?
3. Garments, hairs or anything closer than 1 ft to ESD items measure less than 100V*?
4. Every wrist strap or heel strap/conductive shoes checked daily and result recorded for all DLs?
5. All wrist strap or heel strap checkers calibration up to date?
Note: *50V for Blue LED.
Device Handling
1. Every ESDS items identified by EIA-471 labels on item or packaging?
2. All ESDS items completely inside properly closed static-shielding containers when not at static-safe
workstation?
3. No static charge generators (e.g. plastics) inside shielding containers with ESDS items?
4. All flexible conductive and dissipative package materials inspected before reuse or recycle?
Others
1. Audit result reported to entity ESD control coordinator?
2. Corrective action from previous audits completed?
3. Are audit records complete and on file?
8. Others
White LED is materialized by combining blue LED and phosphors. Color of White LED is changed a little
by an operating current.
The appearance and specifications of the product may be modified for improvement, without prior notice.
