Though EHP-A09 has conducted ESD protection mechanism, customers must not use the device in
reverse and should apply resistors for extra protection. Otherwise, slight voltage difference may cause
enormous current shift and burn out failure would happen.
Do not open the moisture proof bag before the devices are ready to use.
Before the package is opened, LEDs should be stored at temperature less than 30 and humidity
less than 90%.
LEDs should be used within a year.
After the package is opened, LEDs should be stored at temperature less than 30 and humidity
less than 70%.
LEDs should be used within 168 hours (7 days) after the package is opened.
If the moisture absorbent material (silicone gel) has faded away or LEDs have exceeded the
storage time, baking treatment should be implemented based on the following the conditions:
pre-curing at 60±5
For maintaining the high flux output and achieving reliability, EHP-A09 series LEDs should be
mounted on a metal core printed circuit board (MCPCB) or other kinds of heat sink with proper
thermal connection to dissipate approximate 0.5W of thermal energy at 150mA operation.
Special thermal designs are also recommended to take in heat dissipation management, such as
FR4 PCB on Aluminum with thermal vias or FPC on Aluminum with thermal conductive adhesive,
etc.
Sufficient thermal management must be implemented. Otherwise, the junction temperature of dies
might be over the limit at high current driving condition and LEDs’ lifetime might be decreases
dramatically.
For further thermal management suggestions, please consult Everlight Design Guide or local
representatives for assistance.
