Notes :
(1) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram.
Color coordinate : 0.007
(2) Seoul Semiconductor maintains a tolerance of 7% on Intensity and power measurements.
The luminous intensity IV was measured at the peak of the spatial pattern which may not be
aligned with the mechanical axis of the LED package.
(3) Calculated performance values are for reference only.

Caution
(1) Reflow soldering is recommended not to be done more than two times. In the case of more than
24 hours passed soldering after first, LEDs will be damaged.
(2) Repairs should not be done after the LEDs have been soldered. When repair is unavoidable,
suitable tools must be used.
(3) Die slug is to be soldered.
(4) When soldering, do not put stress on the LEDs during heating.
(5) After soldering, do not warp the circuit board.

STW9B12C – Mid-Power LED
Handling of Silicone Resin for LEDs
(1) During processing, mechanical stress on the surface should be minimized as much as possible.
Sharp objects of all types should not be used to pierce the sealing compound.
(2) In general, LEDs should only be handled from the side. By the way, this also applies to LEDs
without a silicone sealant, since the surface can also become scratched.
(3) When populating boards in SMT production, there are basically no restrictions regarding the form
of the pick and place nozzle, except that mechanical pressure on the surface of the resin must be
prevented. This is assured by choosing a pick and place nozzle which is larger than the LED’s
reflector area.
(4) Silicone differs from materials conventionally used for the manufacturing of LEDs. These
conditions must be considered during the handling of such devices. Compared to standard
encapsulants, silicone is generally softer, and the surface is more likely to attract dust.
As mentioned previously, the increased sensitivity to dust requires special care during processing.
In cases where a minimal level of dirt and dust particles cannot be guaranteed, a suitable cleaning
solution must be applied to the surface after the soldering of components.
(5) SSC suggests using isopropyl alcohol for cleaning. In case other solvents are used, it must be
assured that these solvents do not dissolve the package or resin.
Ultrasonic cleaning is not recommended. Ultrasonic cleaning may cause damage to the LED.
(6) Please do not mold this product into another resin (epoxy, urethane, etc) and do not handle this.
product with acid or sulfur material in sealed space.

Product Data Sheet
STW9B12C – Mid-Power LED
Precaution for Use
(1) Storage
To avoid the moisture penetration, we recommend store in a dry box with a desiccant .
The recommended storage temperature range is 5℃ to 30℃ and a maximum humidity of
RH50%.
(2) Use Precaution after Opening the Packaging
Use proper SMT 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. Recommend conditions after opening the package
- Sealing
- Temperature : 5 ~ 40℃ Humidity : less than RH30%
b. If the package has been opened more than 4 week(MSL_2a) or the color of the desiccant
changes, components should be dried for 10-12hr at 60±5℃
(3) Do not apply mechanical force or excess vibration during the cooling process to normal
temperature after soldering.
(4) Do not rapidly cool device after soldering.
(5) Components should not be mounted on warped (non coplanar) portion of PCB.
(6) Radioactive exposure is not considered for the products listed here in.
(7) 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.
(8) 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.
(9) When the LEDs are in operation the maximum current should be decided after measuring the
package temperature.
(10) 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.
(11) The appearance and specifications of the product may be modified for improvement without
notice.
(12) Long time exposure of sunlight or occasional UV exposure will cause lens discoloration.
(13) VOCs (Volatile organic compounds) emitted from materials used in the construction of fixtures
can penetrate silicone encapsulants of LEDs and discolor when exposed to heat and photonic
energy.
The result can be a significant loss of light output from the fixture.
Knowledge of the properties of the materials selected to be used in the construction of fixtures
can help prevent these issues.
(14) Attaching LEDs, do not use adhesives that outgas organic vapor.
(15) The driving circuit must be designed to allow forward voltage only when it is ON or OFF.
If the reverse voltage is applied to LED, migration can be generated resulting in LED damage.
