-3- [ utz-sc0461_0 ] 2016/03/31 ? ? cautions (1) operating method ? the ld shall change its forward voltage requirement and optical output power according to temperat ure change. also, the ld will require more operation current to maintain same output power as it degrades. in order to maintain output power, use of apc (automatic power control) is recommended, which use feedback of the optical output power to adjust the operation current. ? confirm that the optical output power ge nerated by spike current when switching on and off does not exceed the maximum absolute max rating. also, employ appropriate countermeasures to reduce chattering and/or ove rshooting in the circuit. (2) design consideration ? lds may fail as either a short circ uit or an open circuit. if an ld shorts duri ng operation, the forward voltage of the ld may fluctuate greatly. when designing a circuit, ensure that both short and open circuits are consid ered and that there will be no issues if a short or open circuit occurs. (3) static electricity ? static electricity or electrical surges will reduce and degrade the reliability of the lds. it is recommended to use a wrist st rap or anti-electrostatic glove when handling the product. (4) absolute maximum rating ? active layer of lds shall have high current density and generate high electric field during it s operation. in order to prevent excessive damage, the ld must be operated strictly below absolute max rating. ? during operation, if the forward current and/or optical out put power are increased the lifet ime of the lds will decrease. ensure that the lds are operated within the recommended conditions. (5) others ? nichia lds 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 nichias sales staff in adva nce for information on the applications in which exceptional quality and reliability are required, particularly when the failure or malfunction of the lds may directly jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor control systems, automobile s, traffic control equipment, life support systems a nd safety devices). ? the purchaser must acknowledge that any ld can statistically fail and must design its equipments in a fail safe design. prior to use of the ld, please confirm that the ld, as described in nichias specifications, meets th e life expectancy needs of, and provides the features required by the circuit and any related modules, equipment and/or systems. ? nichia prohibits purchaser from reverse engineering, disassembling, or taking any other steps to derive the str ucture or design of the ld. ? the appearance and specifications of the product may be modified for improvement without notice. the formal speci fications must be exchanged and signed by both parties before large volume purchase begins. ? no unauthorized transmission or reproduction of this document, either in whole or in par t, is permitted.
