Precaution for use
• Storage
To avoid the moisture penetration, we recommend storing Z Power LEDs in a dry box
with a desiccant . The recommended storage temperature range is 5C to 30C and a maximum
humidity of 50%.
• Use Precaution after Opening the Packaging
Use proper SMD techniques when the LED is to be soldered dipped as separation of the lens may
affect the light output efficiency.
Pay attention to the following:
a. Soldering should be done immediately after opening the package (within 24Hrs).
b. Required conditions after opening the package
- Sealing
- Temperature : 5 ~ 40
Humidity : less than 30%
c. If the package has been opened more than 1 week or the color of the desiccant changes,
components should be dried for 10-12hr at 60 5
• Do not apply mechanical force or excess vibration during the cooling process to normal
temperature after soldering.
• Do not rapidly cool device after soldering.
• Components should not be mounted on warped (non coplanar) portion of PCB.
• Radioactive exposure is not considered for the products listed here in.
• Gallium arsenide is used in some of the products listed in this publication. These products are
dangerous if they are burned or shredded in the process of disposal. It is also dangerous to
drink the liquid or inhale the gas generated by such products when chemically disposed of.
• This device should not be used in any type of fluid such as water, oil, organic solvent and etc.
When washing is required, IPA (Isopropyl Alcohol) should be used.
• When the LEDs are in operation the maximum current should be decided after measuring the
package temperature.
• LEDs must be stored properly to maintain the device. If the LEDs are stored for 3 months or
more after being shipped from SSC, a sealed container with a nitrogen atmosphere should be used
for storage.
• The appearance and specifications of the product may be modified for improvement without
notice.
• Long time exposure of sunlight or occasional UV exposure will cause lens discoloration.
• The slug is isolated from anode electrically.
Therefore, we recommend that you don’t isolate the heat sink.
• Attaching LEDs, do not use adhesives that outgas organic vapor.
