Datasheet

Operation notes on use
This device is classified as a class Ⅳ laser product, emitting invisible laser radiation.
Direct exposure should be avoid and never look at the emitting surface.
1) Absolute maximum ratings
If an excessively flows in a laser diode, a large optical output will occur and the emitting facet may sustain damage. This opticaldamage can occur even with momentary over-current. For this reason, absolute maximum ratings which must not be exceeded
even momentarily have been established. Exercise particular caution with respect to the drive voltage supply and static
electricity. We guarantee use within the absolute maximum ratings. These ratings are established for a case temperature of
25°C. As the temperature of laser diode increases, its maximum output will decrease and the operating range will shrink. Even
when operated within the absolute maximum ratings, operation at high temperature will result in a shorter life than operation
at low temperature. For this reason, the design should include sufficient margin for heat radiation and light output.
2) Heat radiation conditions
Like other semiconductors, prolonged operation of a laser diode will cause heat to build up at junctions and increased casetemperature. For this reason, attach aluminum (or other) heat sinks (at least 30x30x3mm) to the stem of the laser.
3) Protection against damage due to electrostatic discharge and other current surges
Electrostatic discharge and other current surges can cause deterioration and damage in laser diode, resulting in reduced
reliability. We advise talking the following protective measures.
①
②
③
④
⑤

Ground the device and circuits. Install surge filters, surge reduction transformers, or other electrostatic discharge
protectors in the power supply inputs.
When working with laser diodes wear anti-static clothing, including footwear and caps. Grounded wrist straps should
always be worn while working with laser diodes, and the trap should be grounded through a 1Mohm resistance.
Use anti-static containers for transport and storage.
Laser deterioration and damage can occur due to excessive current spikes when the power is turned on or off. Design
circuits to avoid the generation of excessive current spikes.
Inductive surge near equipment that emits high-frequency EMI can damage or destroy lasers. Avoid using lasers nearfluorescent lamps or other of EMI emissions.

4) Soldering
Use a grounded soldering iron to solder laser leads. Solder at a temperature of no more than 350°C for a maximum of 3
seconds, at a point at least 2mm from the root of the leads.
Please be careful to below points.
The adhesiveness of the die-bonding paste dramatically declines in high temperature, thus the package temperaturemust be observed with extreme care at all times. Please avoid heating the whole package such as reflow soldering.
② It is recommended to heat only one lead frame at a time. (Please avoid heating multiple leads simultaneously.)③ Heating the lead frame will cause the whole package temperature to rise thus it is recommended to release the packageheat by heat sink during soldering.
④ It is recommended to solder the GND lead first to restrain the heat conduction from the lead frame.
①5) In the use of the glue
There is the possibility that the volatilization component of the glue exerts the influence on the characteristic of laser diode.
Please use it after it confirm sufficiently.
6) Handling packages
Packages must not be dropped or subjected to excessive pressure. In the forming processing, be careful not to add stress tothe inner leads and cut wires. Never touch the glass parts of the laser. A damaged or dirtied glass parts will impair the
performance of the laser.
7) Safety
It is extremely dangerous to look, either directly or through a lens, at the laser beam emitted from a laser diode. Use a TV
camera or other similar device to adjust the optical axis.
