Notes :
(1) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram. Color
coordinate : 0.005, CCT 5% tolerance.
(2) Seoul Semiconductor maintains a tolerance of 7% on flux and power measurements.
(3) ФV is the total luminous flux output as measured with an integrating sphere.
(4) Tolerance is 0.06V on forward voltage measurements.
(5) Tolerance is 2.0 on CRI measurements.
* No values are provided by real measurement. Only for reference purpose.

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.

Z5-P1 – High-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) Seoul Semiconductor 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.
(7) Avoid leaving fingerprints on silicone resin parts.

Z5-P1 – High-Power LED
Precaution for Use
(1) Storage
To avoid the moisture penetration, we recommend storing Z5 Series LEDs 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 SMD 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 1 year (MSL 2) 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 Seoul Semiconductor. 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.

Z5-P1 – High-Power LED
Precaution for Use
(13) VOCs (Volatile organic compounds) emitted from materials used in the construction of fixtures ca
n penetrate silicone encapsulants of LEDs and discolor when exposed to heat and photonic energy. T
he result can be a significant loss of light output from the fixture. Knowledge of the properties of the m
aterials selected to be used in the construction of fixtures can help prevent these issues.
(14) The slug is electrically isolated.
(15) Attaching LEDs, do not use adhesives that outgas organic vapor.
(16) The driving circuit must be designed to allow forward voltage only when it is ON or OFF. If the rev
erse voltage is applied to LED, migration can be generated resulting in LED damage.
(17) LEDs are sensitive to Electro-Static Discharge (ESD) and Electrical Over Stress (EOS). Below is
a list of suggestions that Seoul Semiconductor purposes to minimize these effects.
a. ESD (Electro Static Discharge)
Electrostatic discharge (ESD) is the defined as the release of static electricity when two objects come
into contact. While most ESD events are considered harmless, it can be an expensive problem in
many industrial environments during production and storage. The damage from ESD to an LEDs may
cause the product to demonstrate unusual characteristics such as:
- Increase in reverse leakage current lowered turn-on voltage
- Abnormal emissions from the LED at low current
The following recommendations are suggested to help minimize the potential for an ESD event.
One or more recommended work area suggestions:
- Ionizing fan setup
- ESD table/shelf mat made of conductive materials
- ESD safe storage containers
One or more personnel suggestion options:
- Antistatic wrist-strap
- Antistatic material shoes
- Antistatic clothes
Environmental controls:
- Humidity control (ESD gets worse in a dry environment)

Precaution for Use
b. EOS (Electrical Over Stress)
Electrical Over-Stress (EOS) is defined as damage that may occur when an electronic device is
subjected to a current or voltage that is beyond the maximum specification limits of the device.
The effects from an EOS event can be noticed through product performance like:
- Changes to the performance of the LED package
(If the damage is around the bond pad area and since the package is completely encapsulated
the package may turn on but flicker show severe performance degradation.)
- Changes to the light output of the luminaire from component failure
- Components on the board not operating at determined drive power
Failure of performance from entire fixture due to changes in circuit voltage and current across total
circuit causing trickle down failures. It is impossible to predict the failure mode of every LED exposed
to electrical overstress as the failure modes have been investigated to vary, but there are some
common signs that will indicate an EOS event has occurred:
- Damaged may be noticed to the bond wires (appearing similar to a blown fuse)
- Damage to the bond pads located on the emission surface of the LED package
(shadowing can be noticed around the bond pads while viewing through a microscope)
- Anomalies noticed in the encapsulation and phosphor around the bond wires.
- This damage usually appears due to the thermal stress produced during the EOS event.
c. To help minimize the damage from an EOS event Seoul Semiconductor recommends utilizing:
- A surge protection circuit
- An appropriately rated over voltage protection device
- A current limiting device
