Handling Precautions

•

Radiation from the laser can be dangerous; avoid direct eye contact with the laser. Use an infrared camera or IR viewer

to observe the laser light.

•

Semiconductor lasers are sensitive to electrostatic damage. Pack the module with ESD-proof material for carry and

shipment. Carefully ground the working environment, such as working bench, soldering iron, and the workers.

Electrical and Optical Overstress (ESD/EOS) Information

Results of ESD testing indicate that this is a Class I laser with an ESD withstand voltage of 500 V.

Switching transients can cause electrical overstress (EOS) damage in a chip.

EOS may result from improper ESD handling, improper power sequencing, a faulty power supply or an intermittent

connection.

Proper turn-on sequence:

1. All ground connections

2. Most negative supply

3. Most positive supply

4. All remaining connections

Reverse the order to turn off.
