Operation Notes
ESD precautions must be taken when handling unit.
Negative current transients greater than 25 µA and/or reverse voltages >3V can destroy the unit.
Unit requires an adequate heat sink. Failure to supply an adequate heat sink will destroy the unit.
A dry environment should be provided when storing or operating a device with an open diode laser facet at temperatures below the ambient dew point.
Failure to do so will cause condensation on the unit and can destroy it.
