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.
 The use of heat sink is strongly recommended to reduce increases
in temperature.
 Confirm that electrical spike current generated by switching on
VISIBLE AND INVISIBLE LASER RADIATION

Wavelength 375-515nm / Maximum Power: CW >500mW
IEC60825-1: 2007
and off does not exceed the maximum operating current level
specified herein above as absolute max rating. Also, employ appropriate countermeasures to reduce chattering 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 recommended 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 operation. 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 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 LDs may directly jeopardize life or health (such as for airplanes,
aerospace, submersible repeaters, nuclear reactor control systems, automobiles, traffic control equipment, life support
systems and safety devices).
 The Purchaser must acknowledge that any LD can be failed statically and must design its equipments fail 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 may be modified for improvement without notice. The formal
specifications 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 part, is permitted.
