Product Brief
Description
Features and Benefits
•
The Acrich3 series of products are
designed to be driven directly off of AC
line voltage, therefore they do not need
the standard converter essential for
conventional general lighting products.

•
Connects directly to AC line voltage
High Power Efficiency & Factor
Low THD
Long Life Time
Simple BOM
•
The converter or driver found in most
general lighting products can limit the
overall life of the product, but with the
Acrich3 series of products the life of the
product can more closely be estimated
from the LED itself. This will also allow
for a much smaller form factor from an
overall fixture design allowing for higher
creativity in the fixture.
Miniaturization
Lead Free Product
RoHS Compliant
TRIAC Dimming
Key Applications
•
•
•
•
Down Llight
•
The modules have a high power factor
which can contribute to a higher energy
savings in the end application.

Notes :
(1) At 120/220Vac, Ta = 25ºC
(2) ФV is the total luminous flux output measured with an integrated sphere.
(3) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram.
(4) Operating Voltage doesn't indicate the maximum voltage which customers use but means
tolerable voltage according to each country’s voltage variation rate. It is recommended that the
solder pad temperature should be below 70℃.
(5) Surge withstand in accordance with IEC61000-4-5
(6) At 120Vac, seven strikes, 100kHz 2.5kV in accordance with ANSI/IEEE C62.41.2-2002 Category

Notes :
The Acrich3 module is recommended to keep the junction temperature under maximum junction
temperature spec. (Table 5)
LED lead temperature and IC top case temperature are measured with thermocupler. (Fig1)
LED & IC juntion temperatures can be calculated using the formulas below.
Ts_max = Tj_max - (Rθj-s * Pd)
< Example >
If LED lead temperature and IC top temerature are 110℃
1) LED juntion temperature
TJ = TS + (Rθj-s * Pd)
= 110℃ + (9 ℃/W * 0.84W) = 117.56 ℃
2) IC junction temperature
TJ = TS + (Rθj-s * Pd) (1)
= 110℃ + (11.25 ℃/W * 2.8W) = 141.5℃
* (1) : In the example, Pd value is the power consumption of IC when the rated voltage.

Handling of Silicone Resin for LEDs
(1) Acrich3 series is encapsulated with silicone resin for high optical efficiency.
(2) Please do not touch the silicone resin area with sharp objects such as pincette(tweezers).
(3) Finger prints on silicone resin area may affect the performance.
(4) Please store LEDs in covered containers to prevent dust accumulation as this may affect
performance.
(5) Excessive force more than 3000gf to the silicone lens can result in fatal or permanent damage
with LEDs.
(6) Please do not cover the silicone resin area with any other resins such as epoxy, urethane, etc.

Precaution for Use
(1) Please review the Acrich3 Application Note for proper protective circuitry usage.
(2) Please note, Acrich3 products run off of high voltage, therefore caution should be taken when
working near Acrich3 products.
(3) Make sure proper discharge prior to starting work.
(4) DO NOT touch any of the circuit board, components or terminals with body or metal while circuit
is active.
(5) Please do not add or change wires while Acrich3 circuit is active.
(6) Long time exposure to sunlight or UV can cause the lens to discolor.
(7) Please do not use adhesives to attach the LED that outgas organic vapor.
(8) Please do not use together with the materials containing Sulfur.
(9) Please do not assemble in conditions of high moisture and/or oxidizing gas such as Cl, H2S, NH3,
SO2, NOx, etc.
(10) Please do not make any modification on module.
(11) Please be cautious when soldering to board so as not to create a short between different trace
patterns.
(12) Do not impact or place pressure on this product because even a small amount of pressure can
damage the product. The product should also not be placed in high temperatures, high humidity
or direct sunlight since the device is sensitive to these conditions.
(13) When storing devices for a long period of time before usage, please following these guidelines:
* The devices should be stored in the anti-static bag that it was shipped in from
Seoul-Semiconductor with opening.
* If the anti-static bag has been opened, re-seal preventing air and moisture from being present
in the bag.
(14) LEDs and IC are sensitive to Electro-Static Discharge (ESD) and Electrical Over Stress (EOS).
The Acrich3 product should also not be installed in end equipment without ESD protection.
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:

Product Data Sheet
SMJD-XD16W4PX - Acrich3 -16.9W
Precaution for Use
- 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)
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
