ESD failures can be prevented by always wearing wrist straps, only using a grounding workplace, and following strict anti -static guidelines when handling the laser diode.

When handling the LDs, wear appropriate safety glasses to prevent laser light, even any reflections from entering to the eye. Focused laser beam through optical instruments will increase the chance of eye hazard. The LDs are classified in Class 3B of IEC60825-1 and 21 CFR Part 1040.10 Safety Standards . It is absolutely necessary to take overall safety measures against User's modules, equipment and systems into which these LDs are incorporated and/or integrated. Operating Considerations Operating the laser diode outside of its maximum ratings may cause failure or a safety hazard. The diode may be damaged by excessive drive currents or switching transients. If the diode is operated using a power supply, it is strongly recommended to connect the diode with the output voltage set to zero. The voltage should then be increased slowly and with great caution, while at the same time carefully monitoring the laser diodes output power and drive current. The laser diode will show accelerated degradatio n with increased temperature, and it is therefor advised to keep the case temperature low, by means of heat sinking the device. Confirm that electrical spike current generated by switching on 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. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice
