Product Data Sheet Acrich2 – 8.7W Integrated AC LED Solution Acrich2 – 8.7W SMJE-XV08W1P3 MacAdam 3-Step RoHS Product Brief Description Features and Benefits • • • • • • • • • • • The Acrich2 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. The converter or driver found in most general lighting products can limit the overall life of the product, but with the Acrich2 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. The modules have a high power factor which can contribute to a higher energy savings in the end application. Connects directly to AC line voltage High Power Efficiency & Factor Low THD Long Life Time Simple BOM Miniaturization Lead Free Product RoHS Compliant Key Applications • • • • Bulb Llight Down Light Factory Ceiling Light Industrial Light Table 1.

(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℃. Rev5.1, January 15, 2014 3 www.seoulsemicon.com Product Data Sheet Acrich2 – 8.7W Absolute Maximum Ratings Table 4.

The maximum junction temperature of the Acrich2 LED package is 125℃, therefore the maximum lead temperature Ts_max is Ts_max = Tj_max - (Rθj-s * Pd) = 125℃ - (27℃/W * 0.58W) = 109.34℃ Although this is the maximum lead temperature, it is recommended to keep the lead temperature under 70℃.

(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. Rev5.1, January 15, 2014 23 www.seoulsemicon.com Product Data Sheet Acrich2 – 8.7W Precaution for Use (1) Please review the Acrich2 Application Note for proper protective circuitry usage. (2) Please note, Acrich2 products run off of high voltage, therefore caution should be taken when working near Acrich2 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 Acrich2 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, H 2S, 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 Acrich2 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: Rev5.1, January 15, 2014 24 www.seoulsemicon.com Product Data Sheet Acrich2 – 8.7W 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 Rev5.1, January 15, 2014 25 www.seoulsemicon.com Product Data Sheet Acrich2 – 8.7W Company Information Published by Seoul Semiconductor © 2013 All Rights Reserved.
