4N35 Frequently Asked Questions (FAQ)
-
The maximum allowable voltage across the input pins is 5V, but it's recommended to keep it below 4V to ensure reliable operation.
-
To ensure the optocoupler is fully turned off, add a pull-down resistor (e.g., 1 kΩ) between the input pin and ground to discharge the internal capacitance.
-
The minimum current required to trigger the output transistor is typically around 1-2 mA, but this can vary depending on the specific application and desired output current.
-
Yes, but be aware that the 4N35 is not designed to handle high-current or high-voltage switching. Use a suitable relay driver or add additional circuitry to protect the optocoupler.
-
Choose resistor values based on the desired input current, output current, and voltage levels. A good starting point is to use the values recommended in the datasheet or application notes.
