Instructions for Use:

1. Handling and Storage:

   • Store in a dry, cool place to prevent moisture damage.
   • Handle with care to avoid mechanical stress on the leads and package.

2. Mounting:

   • Ensure proper alignment of the leads during soldering to avoid short circuits.
   • Use a heat sink if operating near the maximum power dissipation limit.

3. Electrical Connections:

   • Connect the collector to the positive supply and the emitter to the load or ground.
   • Use appropriate current-limiting resistors to prevent exceeding the maximum collector current.

4. Optical Alignment:

   • Ensure that the phototransistor is aligned with the light source for optimal sensitivity.
   • Shield from ambient light to minimize dark current and improve signal-to-noise ratio.

5. Operating Environment:

   • Operate within the specified temperature range to ensure reliable performance.
   • Avoid exposing the component to temperatures above the maximum storage temperature.

6. Testing:

   • Use a multimeter to measure the dark current and verify the absence of light.
   • Test the responsivity by applying a known light source and measuring the output current.

7. Safety:

   • Follow all safety guidelines when handling and testing electronic components.
   • Do not exceed the maximum ratings to prevent damage to the phototransistor.
