4N35 Frequently Asked Questions (FAQ)
-
The maximum voltage that can be applied to the input pins is 5V. Exceeding this voltage can damage the internal LED.
-
To ensure reliable operation at high temperatures, make sure to derate the current through the LED and the output transistor according to the temperature derating curves provided in the datasheet.
-
The 4N35 is not suitable for high-frequency applications due to its limited bandwidth (around 10 kHz). For high-frequency applications, consider using a faster optocoupler like the 6N137 or 10MBF.
-
The minimum current required to trigger the output transistor is around 1-2 mA, depending on the specific application and the desired output voltage.
-
The 4N35 has a maximum isolation voltage of 2500 Vrms, which is sufficient for many isolation applications. However, for higher isolation voltages, consider using a optocoupler with a higher isolation rating, such as the 4N36 or 4N37.
