4N33 Frequently Asked Questions (FAQ)

  • The 4N33 can operate from -40°C to 100°C, but the maximum junction temperature is 125°C.

  • The 4N33 requires a minimum of 1.4V forward voltage on the LED to ensure proper operation. A series resistor is also recommended to limit the current to the LED.

  • The maximum collector current rating for the 4N33 is 50mA, and the maximum collector-emitter voltage is 30V.

  • The resistor values depend on the specific application and the desired current transfer ratio. A general rule of thumb is to choose a resistor value that limits the LED current to 10-20mA.

  • The 4N33 has a relatively slow switching time (around 10-20μs) and is not suitable for high-frequency applications above 10kHz.
