6. ESD (Electrostatic Discharge)
The package is opened:
Static Electricity or power surge will damage the LED.
Suggestions to prevent ESD damage:
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.
(A) Recommended circuit.
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).
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.
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary.
Recommended soldering conditions:
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.
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics of
