DATASHEET
EHP- B05 Series
Precautions For Use
1. Over-current-Protection
Thought the EHP-B05 series has an ESD protection mechanism, customer must not use the
device in reverse and should apply resistors for extra protection. Otherwise, slight voltage shifts
may cause significant current changes and may cause failure.
2. Storage
i. Do not open the moisture proof bag before the devices are ready to use
ii. Before the package is opened: The LEDs should be stored at temperatures 30℃or less
and humidity 50% or less.
iii. LEDs may be stored for 6 months. When the storage time has reached more than 6 months,
LEDs should be stored in a sealed container filled with Nitrogen gas.
iv. After the package is opened: The LEDs should be stored at temperatures under 30℃ or less
and humidity 30% or less.
v. LEDs should be used within 168 hours (7 days) after the package is opened.
vi. Before using LEDs: The LEDs should be baked under the following conditions: pre-curing at
60±5℃ for 24 hours.
3. Thermal Management
i. For maintaining high flux output and achieving maximum reliability, EHP-B05 series LEDs
should be mounted on a metal core printed circuit board (MCPCB) with proper thermal
connection to dissipate approximately 5W of thermal energy under 700mA operation.
ii. Special thermal designs are also recommended to take into account outer heat sink design,
such as FR4 PCB on Aluminum with thermal vias or FPC on Aluminum with thermal conductive
adhesive, etc.
Recommend:
Max TSlug = 70℃
iii. Sufficient thermal management must be implemented, or the die junction temperature may
exceed the limit and LED lifetime will decrease critically.
