(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 circui t a, the current through the leds may vary due to the variation in forward voltage ch aracteristics 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. for outdoor use, necessary measures should be taken to prevent water, moisture and salt air damage. this led also emits visible light. please take notice of visible light spectrum, in case you use this led as light source of sensors etc. (3) 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 pres sure through wire-bond breaks and package damage may result. when handling the product with tweezers, be careful not to apply excessive force to the resin. otherwise, the resin can be cut, ch ipped, delaminate or deform ed, causing wire-bond breaks and catastrophic failures. dropping the produc t may cause damage. 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. it may cause wi re to break, leading to catastrophic failures.
nichia sts-da1-2396a 15 (4) design consideration although nichia recommends using a copper pcb for this product, customer is advise d to verify the pcb with the products before use. stress during soldering can cause the gl ass lens to break and/or the solder joints to crack. pcb warpage after mounting the products on to 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 mechan ical 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. if an aluminum pcb is used, customer is advised to verity the pcb with the products before use. thermal stress during use can cause the solder joints to crack. (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 wriststrap, es d 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 design ing of commercial products. if tools or equipment contain insulating materials such as glass or plastic, the following measures against electros tatic 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 chec k if the leds are damaged by esd when performing the characteristics inspection of the leds in the application. damage can be detected with a forw ard voltage measurement at low current ( 1ma). esd damaged leds may have current flow at a low voltage. failure criteria: v f <2.0v at i f =0.5ma (6) thermal management proper thermal management is an impo rtant when designing produc ts 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 (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 7c/w w=input power(i f v f ): w ts point
nichia sts-da1-2396a 16 (7) cleaning the leds should not be cleaned. other cleaning agen ts except for freon solvent should be tested prior to use whether they will not affect the package and the gl ass. please note that freon solvent is prohibited worldwide. 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 advise d 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 belo nging 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. the products are uv light leds, and radiate intense uv light during operation. since uv light can be harmful to eyes, do not look directly into the uv light, even through an optical instrument. in case of the light reflection, uv protective glasses ar e required to use in order to avoid damage by the light. (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, submersibl e 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 specificat ions of supplied products before a customer's volume production . specifications and appearance subject to change for improvement without notice.
