Instructions for Use

1. Handling and Storage:

   • Handle the PE-68515 with care to avoid mechanical damage.
   • Store in a dry, cool place within the specified storage temperature range.

2. Mounting:

   • Ensure proper alignment of the pins during mounting.
   • Use a soldering iron set to 260掳C for no more than 10 seconds per joint to avoid damaging the component.

3. Electrical Connections:

   • Connect the collector (C) and emitter (E) terminals correctly to your circuit.
   • Ensure that the maximum ratings for collector-emitter voltage and collector current are not exceeded.

4. Optical Considerations:

   • The phototransistor is sensitive to light in the 830 nm range. Ensure that the light source matches this wavelength for optimal performance.
   • Shield the device from ambient light to prevent unwanted triggering.

5. Testing:

   • To test the phototransistor, apply a known light source and measure the collector current.
   • Verify that the dark current is within the specified range when no light is present.

6. Troubleshooting:

   • If the phototransistor does not respond to light, check the connections and ensure the light source is functioning.
   • If the dark current is higher than expected, check for any sources of ambient light or electrical interference.
