-3- [ ytb-sc0013-01 ] 2012/4/12 cautions (1) operating method the ld shall change its forward voltage requirement and optical output power according to temperature change. also, the ld will require more operation current to maintain same out put power as it degrades. the use of heat sink is strongly recommended to red uce increases in temperature. confirm that electrical spike current generated by switching on and off does not exceed the maximum operating curre nt level specified herein above as absolute max rating. als o, employ appropriate countermeasures to reduce cha ttering and/or overshooting in the circuit. (2) static electricity static electricity or electrical surges will reduce and degrade the reliability of the lds. it is reco mmended to use a wrist strap or anti-electrostatic glove when handling the product. (3) absolute maximum rating active layer of lds shall have high current density and generate high electric field during its operat ion. in order to prevent excessive damage, the ld must be operated s trictly below absolute max rating. (4) others nichia lds described in this brochure are intended to be used for ordinary electronic equipment (such as office equipment, communications equipment, measurement in struments and household appliances). consult nichia ?s sales staff in advance for information on the application s in which exceptional quality and reliability are required, particularly when the failure or malfunction of the lds may directly jeopardize life or health (such a s for airplanes, aerospace, submersible repeaters, nuclear reactor c ontrol systems, automobiles, traffic control equipm ent, life support systems and safety devices). the purchaser must acknowledge that any ld can be f ailed statically and must design its equipments fai l safe design. prior to use of the ld, please confirm that the ld, as described in nichia?s specifications, meets the life expectancy needs of, and provides the features required by the circuit and any related modules, equipment and/or systems. nichia prohibit purchaser from reverse engineering, disassembling, or taking any other steps to derive the structure or design of the ld. the appearance and specifications of the product ma y be modified for improvement without notice. the f ormal specifications must be exchanged and signed by both parties before large volume purchase begins. no unauthorized transmission or reproduction of thi s document, either in whole or in part, is permitte d. visible and invisible laser radiation avoid eye or skin exposure to direct or scattered radiation class 4 laser product wavelength 375-515nm / maximum power: cw >500mw iec60825-1: 2007
