Description
These parts are designed for high current operation and high flux output applications. In
order to solve the high temperature produced by the higher current operation, the package’s
design features better thermal management characteristics than other LED solutions coupled
with an efficient optical design.
This package design allows the lighting designer to reduce the number of LEDs required as
well as the overall lighting system cost. The low profile package can be easily coupled to
reflectors or lenses to efficiently distribute light and provide the desired illuminated appearance.
This product family employs the world’s brightest red, red-orange, amber, blue, cyan, green,
and white LED materials etc., which allow designers to match the color of popular lighting
applications, such as automotive lighting and electronic signs.

1. ØV is the total luminous flux output as measured with an integrating sphere.
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.

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 lead frame 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.

Note: Excessive soldering temperature and/or time might result in deformation of the LED lens or catastrophic
failure of the LED. IR re-flow is not suitable process for through whole type Piranha LED production.

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
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
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 Leeds 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 >[email protected] for InGaN product and >[email protected] for AlInGaP product.
