4. Outline Drawing & Dimension Recommended Land Pattern unit : mm Tolerance : ± 0.13 * This LED has built-in ESD protection device(s) connected in parallel to LED Chip(s). * The thermal pad is electrically isolated from the anode and cathode contact pads. Ts Point & Measurement Method * Measure the nearest point to the thermal pad as shown below. If necessary, remove PSR of PCB to reach Ts point. * Thermal pad must be soldered to the PCB to dissipate heat properly. Otherwise, LED can be damaged.

10. Precaution for use 1) For over current-protection, customers are recommended to apply resistors connected in series with the LEDs to mitigate sudden change of the forward current caused by shift of the 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 cleaning agent. Solvent-based cleaning agent such as Zestron(R) may damage the silicone resins used in the device.
11) Risk of Sulfurization (or Tarnishing) The LED from Samsung Electronics uses a silver-plated lead frame and its surface color may change to black(or dark colored) when it is exposed to sulfur (S), chlorine (Cl) or other halogen compound. Sulfurization of lead frame may cause intensity degradation, change of chromaticity coordinates and, in extreme cases, open circuit. It requires caution.
