-3- [ utz - sc0284_5 ] 2012/10/02 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 output power as it degrades. confirm that the optical output power generated by spike current when switching on and off does not ex ceed the maximum absolute rating. also, employ appropriate counter measures to reduce chattering and/or overshooting i n 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 produ ct. (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 strictly 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 instruments a nd household appliances). consult nichias sales st aff in advance for information on the applications in which exceptiona l quality and reliability are required, particularl y when the failure or malfunction of the lds may directly jeopardize life or health (such as for airplanes, aerospace, subme rsible repeaters, nuclear reactor control systems, automobiles, traffic contr ol equipment, life support systems and safety devic es). 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 descr ibed in nichias specifications, meets the life exp ectancy needs of, and provides the features required by the circuit and a ny 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.
