(2) Failure Criteria Criteria # #1 Items Conditions Failure Criteria Forward Voltage(VF) IF=20mA >U.S.L.×1.1 Luminous Intensity(IV) IF=20mA <L.S.L.×0.7 Reverse Current(IR) VR=5V >U.S.L.×2.0 U.S.L. : Upper Specification Limit L.S.L. : Lower Specification Limit 12 NICHIA STS-DA1-1959 <Cat.No.111027> CAUTIONS (1) Lead Forming ● When forming leads, the leads should be bent at a point at lease 3mm from the base of the epoxy bulb. Do not use the base of the leadframe as a fulcrum during lead forming. ● Lead forming should be done before soldering. ● Do not apply any bending stress to the base of the lead. The stress to the base may damage the LED's characteristics or it may break the LEDs. ● When mounting the product onto a printed circuit board, the via-holes on the board should be exactly aligned with the lead pitch of the product. If the LEDs are mounted with stress at the leads, it causes deterioration of the epoxy resin and this will degrade the LEDs. (2) Storage ● Shelf life of the products in unopened bag is 3 months(max.) at <30°C and 70% RH from the delivery date. If the shelf life exceeds 3 months or more, the LEDs need to be stored in a sealed container with silica gel desiccants to ensure their shelf life will not exceed 1 year. ● Customer is advised to store properly the products in controlled ambient and complete immediately all high temperature related process including soldering as exposure to corrosive environment might cause the plated metal parts of the product to tarnish, which might lead to difficulties in soldering. ● To avoid condensation, the products must not be stored in the areas where temperature and humidity fluctuate greatly. (3) 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) ... ... ● LEDs should be operated in forward bias. Driving circuits must not subject LEDs to either forward or reverse voltage while off. Continuous reverse voltage can cause migration and LED damage. ● For stabilizing the LED characteristics, it is recommended to operate at greater than 10% nominal current. ● Care must be taken to ensure that the reverse voltage will not exceed the Absolute Maximum Rating when using the LEDs with matrix drive. ● For outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage. (4) Handling Precautions ● Do not handle LEDs with bare hands, it may contaminate the LED surface and affect optical characteristics. In the worst case, catastrophic failure from excess pressure through wire-bond breaks and package damage may result. ● Dropping the product may cause damage. ● Do not stack assembled PCBs together. 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. (5) Design Consideration ● PCB warpage after mounting the products onto a PCB can cause the package to break. The LED should be placed in a way to minimize the stress on the LEDs due to PCB bow and twist. ● The position and orientation of the LEDs affect how much mechanical stress is exerted on the LEDs placed near the score lines. The LED should be placed in a way to minimize the stress on the LEDs due to board flexing. ● Board separation must be performed using special jigs, not using hands. 13 NICHIA STS-DA1-1959 <Cat.No.111027> (6) 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 wriststrap, ESD footwear, clothes, and floors Grounded workstation equipment and tools ESD table/shelf mat made of conductive materials ● Proper grounding is required for all devices, equipment, and machinery used in product assembly. Surge protection should be considered when designing of commercial products. ● 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 ● The customer is advised to check if the LEDs are damaged by ESD when performing the characteristics inspection of the LEDs in the application. Damage can be detected with a forward voltage measurement or a light-up test at low current (≤1mA). ● ESD damaged LEDs may have an increased leakage current, current flow at a low voltage or no longer illuminate at a low current. Failure Criteria: VF<2.0V at IF=0.5mA (7) Thermal Management ● Proper thermal management is an important when designing products with LEDs. LED die temperature is affected by PCB thermal resistance and LED spacing on the board. Please design products in a way that the LED die temperature does not exceed the maximum Junction Temperature (TJ). ● Drive current should be determined for the surrounding ambient temperature (TA) to dissipate the heat from the product. (8) Cleaning ● 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. ● 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. (9) 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. 14 NICHIA STS-DA1-1959 <Cat.No.111027> (10) 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. ● Both the customers and Nichia will agree on official specifications of supplied products before a customer's volume production. ● Specifications and appearance subject to change for improvement without notice. 15
