Absolute maximum ratings
Parameter | Symbol | Rating | Unit |
Case Operating Temp | Topr | -20 to 80 | ℃ |
Storage Temp | Tstr | -40 to 105 | ℃ |
Re-flow Soldering Temperature | Tsdr | 260℃(10s) | ℃ |
Reverse Voltage | Vr | 5 | V |
Maximum Continuous Current | Imax | 2 | A |
ESD exposure(Human body) model | ESD | 2000 | V |
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 expended 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：
1. Beam angle is the full angle at the maximum intensity of 1/e^2.
2. Parameters such as Optical power mentioned above will be with 5% tolerance,voltage with 0.1V tolerance,and the wavelength with less than 1nm tolerance.
3. The above test is based on the bench of laser, which facilitates the good thermal conduction.
4. The optical output power can be higher if the diode works in pulsed mode; and the percentage of power increase is determined by duty cycle.
