Pressure can cause nicks, chip-outs, encapsulant delamination and deformation, and wire breaks, decreasing reliability. * Repairing should not be done after the LEDs have been soldered. It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing. * When soldering, do not apply stress to the LED while the LED is hot. * When using a pick and place machine, choose an appropriate nozzle for this product. Using a pick-and-place nozzle with a smaller diameter than the size of the LED's emitting surface will cause damage to the emitting surface and may also cause the LED not to illuminate. * When flux is used, it should be a halogen free flux. Ensure that the manufacturing process is not designed in a manner where the flux will come in contact with the LEDs. * During and/or after soldering an electric wire to the electrode, ensure that tension is not applied to the electric wire. This may cause the electrode to be damaged and/or reduce the adhesive strength of the electrode to the package. * If soldering is used to join electric wires to the electrodes, the adhesive strength of the electrode to the package may be reduced depending on the substances that are found in the solder paste and/or the type of the wire cover that is used. Ensure that there are no issues with the materials that will be used in the chosen application prior to use. 5 NICHIA STS-DA1-3036B <Cat.No.150401> TRAY DIMENSIONS * 数量は1トレイにつき 42個入りです。 Tray Size: 42pcs 寸法は参考です。 * All dimensions shown are for reference only and are not guaranteed. 管理番号 No. NxxxJ130x STS-DA7-5788 (単位 Unit: mm) 297 210 7 19 .7 145 210 29 35 24.7 6 NICHIA STS-DA1-3036B <Cat.No.150401> PACKAGING - TRAY PACK シリカゲルとともにトレイをアルミ防湿袋に入れ、熱シールにより封をします。 Trays are shipped with desiccants in heat-sealed moisture-proof bags. トレイ Tray シリカゲル Desiccants 管理番号 No. Nxxxxxxx STS-DA7-5106 ラベル Label XXXX LED TYPE Nxxxxxxx ******* LOT YMxxxx-RRR QTY.

Unused remaining LEDs should be stored with silica gel desiccants in a hermetically sealed container, preferably the original moisture-proof bags for storage. ● Although the leads or electrode pads (anode and cathode) of the product are plated with gold, prolonged exposure to a corrosive environment might cause the gold plated the leads or electrode pads to tarnish. If unused LEDs remain, they must be stored in a hermetically sealed container. Nichia recommends using the original moisture-proof bag for storage. ● Do not use sulfur-containing materials in commercial products. Some materials, such as seals and adhesives, may contain sulfur. The contaminated plating of LEDs might cause an open circuit. Silicone rubber is recommended as a material for seals. Bear in mind, the use of silicones may lead to silicone contamination of electrical contacts inside the products, caused by low molecular weight volatile siloxane. ● To prevent water condensation, please avoid large temperature and humidity fluctuations for the storage conditions. ● Do not store the LEDs in a dusty environment. ● Do not expose the LEDs to direct sunlight and/or an environment where the temperature is higher than normal room temperature. (2) Directions for Use ● When designing a circuit, the current through each LED must not exceed the Absolute Maximum Rating. Operating at a constant current per LED is recommended. In case of operating at a constant voltage, Circuit B is recommended. If the LEDs are operated with constant voltage using Circuit A, the current through the LEDs may vary due to the variation in Forward Voltage characteristics of the LEDs. (A) (B) ... ... ● This product should be operated using forward current. Ensure that the product is not subjected to either forward or reverse voltage while it is not in use. In particular, subjecting it to continuous reverse voltage may cause migration, which may cause damage to the LED die. When used in displays that are not used for a long time, the main power supply should be switched off for safety. ● Pulse width modulation (PWM) is recommended for dimming LEDs as color point changes with drive current. ● It is recommended to operate the LEDs at a current greater than 10% of the sorting current to stabilize the LED characteristics. ● Ensure that excessive voltages such as lightning surges are not applied to the LEDs. ● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage. (3) Handling Precautions ● Do not handle the LEDs with bare hands as it will contaminate the LED surface and may affect the optical characteristics: it might cause the LED to be deformed and/or the wire to break, which will cause the LED not to illuminate. ● When handling the product with tweezers, be careful not to apply excessive force to the resin. Otherwise, The resin can be cut, chipped, delaminate or deformed, causing wire-bond breaks and catastrophic failures. ● Dropping the product may cause damage. ● Do not stack assembled the products. Failure to comply can cause the resin portion of the product to be cut, chipped, delaminated and/or deformed. It may cause wire to break, leading to catastrophic failures. 20 NICHIA STS-DA1-3036B <Cat.No.150401> (4) Design Consideration ● Volatile organic compounds that have been released from materials present around the LEDs (e.g. housing, packing, adhesive, secondary lens, lens cover, etc.) may penetrate the LED lens and/or encapsulating resin. If the LEDs are being used in a hermetically sealed environment, these volatile compounds can discolor after being exposed to heat and/or photon energy and it may greatly reduce the LED light output and/or cause a color shift. In this case, ventilating the environment may improve the reduction in light output and/or color shift. Perform a light-up test of the chosen application for optical evaluation to ensure that there are no issues, especially if the LEDs are planned to be used in a hermetically sealed environment. ● Excessive forces on this product can cause the ceramic package to crack. It is recommended to use a holder when fixing this product to a chassis. ● It is recommended to use a thermal film or thermal grease between the product and a chassis for increased heat dissipation. (5) Electrostatic Discharge (ESD) ● The products are sensitive to static electricity or surge voltage. ESD can damage a die and its reliability. When handling the products, the following measures against electrostatic discharge are strongly recommended: Eliminating the charge Grounded wrist strap, ESD footwear, clothes, and floors Grounded workstation equipment and tools ESD table/shelf mat made of conductive materials ● Ensure that tools (e.g. soldering irons), jigs and machines that are being used are properly grounded and that proper grounding techniques are used in work areas. For devices/equipment that mount the LEDs, protection against surge voltages should also be used. ● If tools or equipment contain insulating materials such as glass or plastic, the following measures against electrostatic discharge are strongly recommended: Dissipating static charge with conductive materials Preventing charge generation with moisture Neutralizing the charge with ionizers (6) Thermal Management ● Proper thermal management is an important when designing products with LEDs. LED die temperature is affected by LED module thermal resistance and LED spacing. Please design products in a way that the LED die temperature does not exceed the maximum Junction Temperature (TJ). ● The dice temperature of the products should be calculated, using the case temperature (TC) of the product incorporated into the end-product, by the following equation. TJ=TC+RθJC･W *TJ=LED junction temperature: °C TC=Case temperature: °C RθJC=Thermal resistance from junction to TC measuring point: °C/W W=Input power(IF×VF): W Tc Point 21 NICHIA STS-DA1-3036B <Cat.No.150401> (7) Cleaning ● The LEDs should not be cleaned with water, benzine, and/or thinner. ● If required, isopropyl alcohol (IPA) should be used. Other solvents may cause premature failure to the LEDs due to the damage to the resin portion. The effects of such solvents should be verified prior to use. In addition, the use of CFCs such as Freon is heavily regulated. ● When dust and/or dirt adheres to the LEDs, soak a cloth with Isopropyl alcohol (IPA), then squeeze it before wiping the LEDs. ● Ultrasonic cleaning is not recommended since it may have adverse effects on the LEDs depending on the ultrasonic power and how LED is assembled. If ultrasonic cleaning must be used, the customer is advised to make sure the LEDs will not be damaged prior to cleaning. (8) Eye Safety ● In 2006, the International Electrical Commission (IEC) published IEC 62471:2006 Photobiological safety of lamps and lamp systems, which added LEDs in its scope. On the other hand, the IEC 60825-1:2007 laser safety standard removed LEDs from its scope. However, please be advised that some countries and regions have adopted standards based on the IEC laser safety standard IEC 60825-1:20112001, which still includes LEDs in its scope. Most of Nichia's LEDs can be classified as belonging into either the Exempt Group or Risk Group 1. High-power LEDs, that emit light containing blue wavelengths, may be classified as Risk Group 2. Please proceed with caution when viewing directly any LEDs driven at high current, or viewing LEDs with optical instruments which may greatly increase the damages to your eyes. ● Viewing a flashing light may cause eye discomfort. When incorporating the LED into your product, please be careful to avoid adverse effects on the human body caused by light stimulation. (9) Others ● The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment, communications equipment, measurement instruments and household appliances). Consult Nichia's sales staff in advance for information on the applications in which exceptional quality and reliability are required, particularly when the failure or malfunction of the LEDs may directly jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor control system, automobiles, traffic control equipment, life support systems and safety devices). ● The customer shall not reverse engineer by disassembling or analysis of the LEDs without having prior written consent from Nichia. When defective LEDs are found, the customer shall inform Nichia directly before disassembling or analysis. ● The specifications and appearance of this product may change without notice; Nichia does not guarantee the contents of this specification. Both the customer and Nichia will agree on the official specifications of supplied products before the volume production of a program begins. 22
