About this product
The 4N32 is a DC-input optocoupler that electrically isolates a control circuit from a load circuit using an infrared LED and a photodarlington output transistor. Its exposed base pin lets designers adjust gain or switching speed. It is used for microcontroller interfacing, switching and signal isolation up to 5.3 kVRMS.

Frequently asked questions
What is the price of 4N32 DC-Input Optocoupler Photodarlington, PDIP-6 in Egypt?
4N32 DC-Input Optocoupler Photodarlington, PDIP-6 currently costs 4 EGP in Egypt.
Where can I buy 4N32 DC-Input Optocoupler Photodarlington, PDIP-6 in Egypt?
4N32 DC-Input Optocoupler Photodarlington, PDIP-6 is available from Makers Electronics. Compare the offers above to find the best price.
What is the base pin used for?
Leaving the base unconnected is the normal setup. A resistor between base and emitter can be added to reduce gain and speed up turn-off, which helps when the output switches too slowly.
How do I drive the input LED side?
Drive the input LED from a microcontroller pin through a series resistor sized for the LED current you need. The datasheet test condition is around 10 mA.
