4. Outline Drawing & Dimension
Notes:
1) This LED has built-in ESD protection device(s) connected in parallel to LED chip(s).
2) The thermal pad is electrically isolated from the anode and cathode contact pads.
3) Ts point and measurement method:
① Measure the nearest point to thermal pad as shown above. If necessary, remove PSR of PCB to reach Ts point.
② All pads must be soldered to the PCB to dissipate heat properly, otherwise the LED can be damaged.
Precautions:
1) Pressure on the LEDs will influence to the reliability of the LEDs. Precautions should be taken to avoid strong pressure on
the LEDs. Do not put stress on the LEDs during heating.
2) Re-soldering should not be done after the LEDs have been soldered. If re-soldering is unavoidable, LED`s characteristics
should be carefully checked before and after such repair.
3) Do not stack assembled PCBs together. Since materials of LEDs is soft, abrasion between two PCB assembled with LED
might cause catastrophic failure of the LEDs.

10. Precautions in Handling & Use
1) For over-current protection, users are recommended to apply resistors connected in series with the LEDs to mitigate
sudden change of the forward current caused by shift of forward voltage.
2) This device should not be used in any type of fluid such as water, oil, organic solvent, etc. When cleaning is required, IPA
is recommended as the cleaning agent. Some solvent-based cleaning agent may damage the silicone resins used in the
device.
3) When the device is in operation, the forward current should be carefully determined considering the maximum ambient
temperature and corresponding junction temperature.
4) LEDs must be stored in a clean environment. If the LEDs are to be stored for three months or more after being shipped
from Samsung, they should be packed with a nitrogen-filled container (shelf life of sealed bags is 12 months at
temperature 0~40 ºC, 0~90 % RH).
5) After storage bag is opened, device subjected to soldering, solder reflow, or other high temperature processes must be:
a. Mounted within 672 hours (28 days) at an assembly line with a condition of no more than 30 ºC / 60 % RH, or
b. Stored at <10 % RH
6) Repack unused devices with anti-moisture packing, fold to close any opening and then store in a dry place.
7) Devices require baking before mounting, if humidity card reading is >60 % at 23 ± 5 ºC.
8) Devices must be baked for 1 hour at 60 ± 5 ºC, if baking is required.
9) The LEDs are sensitive to the static electricity and surge current. It is recommended to use a wrist band or anti-
electrostatic glove when handling the LEDs. If voltage exceeding the absolute maximum rating is applied to LEDs, it may
cause damage or even destruction to LED devices. Damaged LEDs may show some unusual characteristics such as
increase in leakage current, lowered turn-on voltage, or abnormal lighting of LEDs at low current.
10) VOCs (Volatile Organic Compounds) can be generated from adhesives, flux, hardener or organic additives used in
luminaires (fixtures). Transparent LED silicone encapsulant is permeable to those chemicals and they may lead to a
discoloration of encapsulant when they exposed to heat or light. This phenomenon can cause a significant loss of light
emitted (output) from the luminaires. In order to prevent these problems, we recommend users to know the physical
properties of materials used in luminaires and they must be carefully selected.
