Note：
1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at these or other conditions
above those indicated in the operations section for extended periods of time may affect reliability.
2. In its maximum rating diode laser operation could damage its performance or cause potential safety
hazard such as equipment failure.
3. Electrostatic discharge is the main reason for the laser fault of the diode. Take effective precautions
against ESD. When dealing with laser diodes, use the wrist strap, grounding work surface and strict
antistatic technology.

Note：There may be some changes between sample and drawing， thus，the actual spec please refer to
the sample that you received. And if any question please contact us.
V. SMT reflow soldering curve
Note: Reflow soldering can be operated only one time. During the temperature ramp-up, no forces
may be exerted on the LD which could deform or damage them. After soldering completed, please
also do not process until the product temperature ramp down to room temperature.
VI. Treatment and protection measures

Soldering precautions
For AlN or FeNi Alloy substrate, the temperature of soldering iron must be controlled under
260℃ during manual soldering; for Cu/Ag substrate, the temperature of soldering iron must be
controlled under 180℃ during manual soldering; for Bismaleimide Triazine (BT) substrate, the
temperature of soldering iron must be controlled under 240℃ during manual soldering. Also,
VCSEL can be only soldered one time with the soldering time less than 3s. But, It is very hard
to control the soldering temperature and homogenize solder paste because of the smaller size of
VCSEL. In addition, it is easy to damage VCSEL structure even causes VCSEL losing efficacy.
So, we advise you to use re-flow soldering machine for operation.
Storage precautions
Our products were sealed by aluminum foil bag attaching packed desiccant, they are
moisture proof and anti-static. Please handle these gently to avoid damage. At the same time,
please be ready for storage and take some moisture-proof measures to keep VCSEL away from
dampness that may causes reliability failure.
Before opening, VCSEL must be saved for at least 90 days below 30℃ with 60%RH.
After opening, VCSEL must be kept in an environment that temperature lower than 30℃
and humidity lower than 60%RH and used up within 24 hours. When the storage humidity
reaches and exceeds 60%, the products must be dehumidified at 60°C for more than 24hours
before use.
Others
1. Please use solder paste to cure the laser diode.
2. Please make sure that the heat of LD has been completely conducted to metal shell, to
avoid affecting the optical power output.
3. This LD can be only used in constant voltage and current.
4. Operating voltage and current, refer to the table in paragraph Ⅱ.
5. Please do not aim the laser to people or animal.
6. You can observe the laser spot through an image monitoring equipment.
7. Please do not touch LD surface by naked hands or squeeze the sealant on LD surface, or
it may cause wrong optical angle and distorted laser spot, even damage the LD.
8. Please use ceramic suction nozzle to absorb the LD, so as to avoid LD sticking to the
nozzle.
9. Please add a 0.02s blowing action after locating the laser diode to aluminum substrate.
