(2) directions for use in designing a circuit, the current through each led must not exceed the absolute maximum rating specified for each led. it is recommended to use circuit b which regulates the current flowing th rough 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 ch aracteristics of the leds. (a) ... (b) ... this product should be operated in forwar d bias. a driving circuit must be designed so that the product is not subjected to either forw ard or reverse voltage while it is off. in particular, if a reverse voltage is continuously applied to the product, such operation can cause migration resulting in led damage. for stabilizing the led characteristics, it is recommended to operate at 10% of the rated current or higher. for outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage.
nichia sts-da1-1332a 15 (3) handling precautions when handling the product, do not touch it directly with bare hands as it may contaminate the surface and affect on optical characteristics. in the worst cases, excessive force to the product might result in catastrophic failu re due to package damage and/or wire breakage. when handling the product with tweezers, make sure that excess ive force is not applied to the resin portion of the product. failure to comply can cause the resin portion of the pr oduct to be cut, chipped, delaminated and/or deformed, and wire to be broken, and thus resulting in catastrophic failure. if the product is dropped, it might be damaged. do not stack assembled pcbs together. fa ilure to comply can cause the resin portio n of the product to be cut, chipped, delaminated and/or deformed, and wire to be br oken, and thus resulting in catastrophic failure. (4) design consideration pcb warpage after mounting the products on to a pcb can cause the package to break. the leds should be placed so as to minimize the stress on the leds due to pcb bow and twist. the position and orientation of the leds affect how much mechan ical stress is exerted on the leds placed near the score lines. the leds should be placed so as to minimi ze the stress on the leds due to board flexing. board separation must be performed using special jigs, not with hands. (5) electrostatic discharge (esd) the products are sensitive to static electricity or surge voltage. an esd event may damage its die or reduce its reliability performance. when handling the products, measures against electro static discharge, including the followings, are strongly recommended. eliminating the charge; wrist strap, esd footwear and garments, esd floors grounding the equipment and tools at workstation esd table/shelf mat (conductive materials) proper grounding techniques are required for all devices, eq uipment and machinery used in the assembly of the products. also note that surge protection should be considered in the design of customer products. if tools or equipment contain insulating materials, such as glass or plastic, proper measures against electro static discharge , including the followings, are strongly recommended. dissipating the charge with conductive materials preventing the charge generation with moisture neutralizing the charge with ionizers when performing the characteristics inspection of the leds in your application, customer is advised to check on the leds whether or not they are damaged by esd. such damage can be detected during forward voltage measurement or light up test at low current. (the recomm ended current is 1ma or lower) esd-damaged leds may have a current flow at low voltage, or no longer light up at low current. failure criteria: v f <2.0v at i f =0.5ma
nichia sts-da1-1332a 16 (6) thermal management thermal management is an important factor wh en designing your prod uct by using the leds. the rise in led die temperature can be affected by pcb th ermal resistance or/and led spac ing as mounted on the board. customer is advised to design the product to ensure that the led die temperature does not exceed the required maximum junction temperature (t j ). drive current should be determined for the surrounding ambient temperature (t a ) to dissipate the heat from the product. the following equations can be used to calculate the junction temperature of the products. 1) t j =t a +r ja ? w 2) t j =t s +r js ? w *t j =led junction temperature: c t a =ambient temperature: c t s =soldering temperature (cathode side): c r ja =thermal resistance from junction to ambient: c/w r js = thermal resistance from junction to t s measuring point: c/w w=input power(i f v f ): w ts point (7) cleaning if required, isopropyl alcohol (ipa) should be used. ot her 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 for the leds since it may adverse ly effect on the leds by the ultrasonic power and led assembled condition. if it is unavoidable, customer is advised to check prior to use that the cleaning will not damage the leds. (8) eye safety the international electrical commission (iec) publis hed in 2006, iec 62471:2006 photobiological safety of lamps and lamp systems which includes leds within its scope. meanwhile leds were removed from the scope of the iec 60825-1:2007 laser safety standard, the 2001 edition of which included led sources within its scope. however, keep it mind that some countries and regions have adopted standards based on the iec laser safety standard iec 60825-1:2001 which includes leds within its scope. follo wing iec 62471:2006, most of nichia leds can be classified as belonging to either exempt group or risk group 1. especially a high-power led, that emits light containing blue wavelengt hs, may be in risk group 2. great care should be taken when viewing directly the led driven at high current or the led with optical instruments, which grea tly increase the hazard to your eyes. viewing a flashing light may cause eye discomfort. when incorporating the led into your product, precaution should be taken to avoid adverse e ffect on human body caused by the light stimulus. (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 applicat ions 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, submersibl e repeaters, nuc lear 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. customer and nichia shall agree the official specification of su pplied products prior to the star t of a customer?s volume prod uction. the appearance and specifications of the product may be modified for improvement without notice.
