There is a possibility that this can cause exfoliation of the contacts and damage the optical characteristics of the LEDs. For this reason, the moisture proof package is used to keep moisture to a minimum in the package. · The moisture proof package is made of an aluminum moisture proof bag. A package of a moisture absorbent material (silica gel) is inserted into the aluminium moisture proof bag. The silica gel changes its color from blue to pink as it absorbs moisture. (2) Storage · Storage Conditions Before opening the package : The LEDs should be kept at 30°C or less and 90%RH or less. The LEDs should be used within a year. When storing the LEDs, moisture proof packaging with absorbent material (silica gel) is recommended. After opening the package : The LEDs should be kept at 30°C or less and 70%RH or less. The LEDs should be soldered within 168 hours (7days) after opening the package. If unused LEDs remain, they should be stored in the moisture proof packages, such as sealed containers with packages of moisture absorbent material (silica gel). It is also recommended to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again. · If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be performed using the following condition. Baking treatment : more than 24 hours at 65 ± 5°C · This product has silver plated metal parts that are inside and/or outside the package body. The silver plating becomes tarnished when being exposed to an environment which contains corrosive gases. Any LED with tarnished leads may lead to poor solderability and deterioration of optical characteristics. Please do not expose the LEDs to corrosive atmosphere during storage. · After assembly and during use, silver plating can be affected by the corrosive gases emitted by components and materials in close proximity of the LEDs within an end product, and the gases entering into the product from the external atmosphere. The above should be taken into consideration when designing. · Please avoid rapid transitions in ambient temperature, especially in high humidity environments where condensation can occur. -4- Nichia STS-DA1-0051 <Cat.No.071228> (3) Static Electricity · Static electricity or surge voltage damages the LEDs. It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs. · All devices, equipment and machinery must be properly grounded. It is recommended that precautions be taken against surge voltage to the equipment that mounts the LEDs. · When inspecting the final products in which LEDs were assembled, it is recommended to check whether the assembled LEDs are damaged by static electricity or not. It is easy to find static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended). · Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA) (4) Application Design Considerations · In designing a circuit, the current through each LED must not exceed its absolute maximum rating. It is recommended to use Circuit B which regulates the current flowing through each LED. In the meanwhile, when driving LEDs with a constant voltage in Circuit A, the current through the LEDs may vary due to the variation in forward voltage (VF) of the LEDs. In the worst case, some LED may be subjected to stresses in excess of the absolute maximum rating. (B) (A) ... ... · Thermal design of the end product is of paramount importance. Please consider the heat generation of the LED when making the system design. The coefficient of temperature increase per input electric power is affected by the thermal resistance of the circuit board and density of LED placement on the board, as well as other components. It is necessary to avoid intense heat generation and operate within the maximum ratings given in this specification. · Please determine the operating current with consideration of the ambient temperature local to the LED and refer to the plot of Ambient temperature vs. Allowable Forward Current on CHARACTERISTICS in this specifications. Please also take measures to remove heat from the area near the LED (heat sink) to improve the operational characteristics of the LED. · The equation 1 indicates correlation between Tj and Ta, and the equation 2 indicates correlation between Tj and Tc. Tj=Ta + Rja W 1 Tj=Tc + Rjc W 2 Tj = Dice Temperature : °C, Ta = Ambient Temperature : °C, Tc = Die Heat sink Temperature : °C, Rja = Heat resistance from Dice to Ambient temperature : °C /W, Rjc = Heat resistance from Dice to Tc measuring point ≒ 10°C /W, W = Inputting Power (IF VF) : W -5- Nichia STS-DA1-0051 <Cat.No.071228> · Warpage of circuit board with soldered LEDs may result in damage or package breakage of the LEDs. Please pay special attention to the orientation of the LEDs as to avoid LED failure caused by bow, twist and warpage of the board. 【Non-preferable】 【Preferable】 Cathode mark Cathode mark Solder connections Solder connections When mechanical stress from the board affects the soldered LED, place the LED in the preferable location and orientation as shown above. · When separating the circuit boards with soldered LEDs, please use appropriate tools and equipment. Hand brake without these tools and equipment may not be used. · The use of aluminum substrate increases stress to solder joints due to thermal expansion of substrate and subsequently may result in solder joint crack. Users may need to evaluate their specific application to determine any impact due to the use of aluminum substrate. -6- Nichia STS-DA1-0051 <Cat.No.071228> (5) Handling Precautions · Bare Hand When handling the product, touching encapsulant with bare hands will contaminate its surface that could affects on optical characteristics. In the worst cases, excessive force to the encapsulant by hands might result in catastrophic failure of the LEDs due to wire deformation and/or breakage. · Tweezers When handling it with tweezers, the product should only be held by the ceramic body, not by the encapsulant. Failure to comply might result in chip-out and/or delamination of encapsulant, and in the worst cases, catastrophic failure of the LEDs due to wire deformation and/or breakage. Encapsulant Ceramic body · Pick and Place Recommended conditions : Area of outer nozzle ≥ 2 mm2 (more than 30% of encapsulant top surface)** Contact area of nozzle with encapsulant ≥ 0.9 mm2 (15 to 85% of encapsulant top surface)** Placement pressure ≤ 3N/mm2 *max. force : 5N Vacuum pressure ≤ 7.8N/ cm2 (≤ 0.8 kgf/cm2) **For reference. Failure to comply might result in damage to encapsulant and in the worst cases, catastrophic failure of the LEDs due to wire deformation and/or breakage. -7- Nichia STS-DA1-0051 <Cat.No.071228> · Printed Circuit Board Assembled (PCB with LEDs soldered) Do not stack assembled PCBs together. Since silicone is a soft material, abrasion between two PCB assembled with silicone encapsulated LED might cause catastrophic failure of the LEDs due to damage to encapsulant (such as scratch, chip-out and delamination) and wire (such as deformation and breakage) and LED detachment. -8- Nichia STS-DA1-0051 <Cat.No.071228> (6) Soldering Conditions · The LEDs can be soldered in place using the reflow soldering method. Nichia cannot make a guarantee on the LEDs after they have been assembled using the dip or hand soldering method. · Recommended soldering conditions Reflow Soldering Lead Solder Lead-free Solder Pre-heat 120 ~ 150°C 180 ~ 200°C Pre-heat time 120 sec.

It is recommended that the User use the nitrogen reflow method. · Repairing should not be done after the LEDs have been soldered. When repairing is unavoidable, a hot plate should be used. It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing. · Reflow soldering should not be done more than two times. · Die Heat sink is to be soldered. If not, please use the heat conductive adhesive. · When soldering, do not put stress on the LEDs during heating. · After soldering, do not warp the circuit board. -9- Nichia STS-DA1-0051 <Cat.No.071228> (7) Cleaning · It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs. When using other solvents, it should be confirmed beforehand whether the solvents will dissolve the package and the resin or not. Freon solvents should not be used to clean the LEDs because of worldwide regulations. · Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence of ultrasonic cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition. Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur. (8) Others · NJSG107 complies with RoHS Directive. · The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent looking directly at the LEDs with unaided eyes for more than a few seconds. · Flashing lights have been known to cause discomfort in people; you can prevent this by taking precautions during use. Also, people should be cautious when using equipment that has had LEDs incorporated into it. · 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 systems, automobiles, traffic control equipment, life support systems and safety devices). · User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written consent from Nichia. When defective LEDs are found, the User shall inform Nichia directly before disassembling or analysis. · The formal specifications must be exchanged and signed by both parties before large volume purchase begins. · The appearance and specifications of the product may be modified for improvement without notice. -10- Nichia STS-DA1-0051 <Cat.No.071228> ICI Chromaticity Diagram 0.9 520 530 0.8 540 510 0.7 G H 550 560 0.6 570 500 0.5 y 580 590 0.4 600 0.3 610 620 630 490 0.2 480 0.1 470 460 0 0 0.1 0.2 0.3 0.4 x ½ Color Coordinates Measurement allowance is ± 0.01 -11- 0.5 0.6 0.7 0.8 100 50 1.5 1.0 0.5 0 200 400 600 800 1000 Forward Current IFP (mA) Ambient Temperature vs. Forward Voltage Ambient Temperature vs. Relative Luminous Flux 5.5 2.0 5.0 IFP=350mA 4.5 4.0 3.5 3.0 2.5 -60 -40 -20 0 20 40 60 80 100 Ambient Temperature Ta (°C) Relative Luminous Flux (a.u.) -12- Forward Voltage VF (V) Ta=25°C 2.0 0 10 2.5 3.0 3.5 4.0 4.5 5.0 5.5 Forward Voltage VF (V) Allowable Forward Current IFP (mA) Ta=25°C 350 1000 800 2.5 IFP=350mA 1.0 0.5 0.2 -60 -40 -20 0 20 40 60 80 100 Ambient Temperature Ta (°C) 500 Ta=25°C 200 100 1 5 10 20 50 100 Duty Ratio (%) Ambient Temperature vs. Allowable Forward Current Allowable Forward Current IF (mA) Relative Luminous Flux (a.u.)
