Instructions:

1. Forward Current (IF):

   • Ensure the forward current through the LED does not exceed 100 mA to prevent damage.
   • Typical operating current is around 50 mA.

2. Forward Voltage (VF):

   • The forward voltage drop across the LED is typically between 1.1 V and 1.6 V. Design your circuit to accommodate this voltage drop.

3. Reverse Voltage (VR):

   • Do not apply more than 5 V in reverse across the LED to avoid breakdown.

4. Reverse Current (IR):

   • The reverse leakage current should not exceed 100 渭A. This is typically very low but should be considered in sensitive circuits.

5. Output Current (IOT):

   • The maximum output current through the phototransistor is 20 mA. Ensure your load can handle this current.

6. Collector-Emitter Voltage (VCE):

   • The maximum voltage between the collector and emitter should not exceed 30 V.

7. Collector-Emitter Saturation Voltage (VCESAT):

   • When the phototransistor is fully on, the voltage between the collector and emitter will be between 0.4 V and 0.8 V.

8. Storage Temperature (Tstg):

   • Store the device in a temperature range from -40掳C to 110掳C to ensure reliability.

9. Operating Temperature (Topr):

   • Operate the device within the temperature range of -40掳C to 100掳C for continuous use.

10. Handling:

    • Handle with care to avoid mechanical stress or damage.
    • Follow ESD (Electrostatic Discharge) precautions to prevent damage from static electricity.

11. Mounting:

    • Use appropriate soldering techniques and temperatures to avoid thermal shock.
    • Ensure proper orientation during assembly to avoid incorrect connections.
