Precautions for Operation
2 pieces of photodiodes are built in this device to amplify difference in collector current between them.
Radiation of even light to 2 pieces of photodiodes is recommended.
Radiation of uneven light may cause change of spectral sensitivity or starting failure of the circuit after power is supplied.
• Conduct cleaning as follows.
Solvent dip cleaning : Solvent temperature of 45˚C max., dipping time : Within 3 minutes
Ultrasonic cleaning : Elements are affected differently depending on the size of cleaning bath, ultrasonic output, time, size of PWB and mounting
• Use following solvents only.
Be sure to perform soldering at values within the maximum ratings. Take care so that not external force is applied to
the lead during and immediately after soldering. Do not perform reflow soldering.
