Instructions for Use:

1. Mounting and Handling:

   • Handle the device with care to avoid mechanical damage.
   • Ensure proper alignment during mounting to prevent short circuits or incorrect connections.

2. Electrical Connections:

   • Connect the anode (pin 1) to the positive side of the input circuit.
   • Connect the cathode (pin 2) to the negative side of the input circuit.
   • Connect the emitter (pin 3) to the ground of the output circuit.
   • Connect the collector (pin 4) to the load and the positive side of the output circuit.

3. Operating Conditions:

   • Ensure that the forward current (IF) does not exceed 60 mA to prevent damage to the LED.
   • Keep the collector-emitter voltage (VCE) below 70 V to avoid breakdown.
   • Operate the device within the temperature range of -40掳C to 110掳C to ensure reliable performance.

4. Storage:

   • Store the device in a dry, cool place within the temperature range of -40掳C to 125掳C.

5. Testing:

   • Use a multimeter to check the continuity and resistance values between the pins to ensure the device is functioning correctly.
   • Measure the current transfer ratio (CTR) under typical operating conditions to verify performance.

6. Safety:

   • Always follow safety guidelines when handling high voltages and currents.
   • Use appropriate protective equipment and follow all relevant standards and regulations.
