About this product
A surface-mount optocoupler in which an infrared LED drives a phototransistor, providing electrical isolation between two circuits. It lets one circuit switch or sense another while the two stay electrically separated, which protects control electronics from faults on the other side.

Frequently asked questions
What is the price of 4N25S SMD Optocoupler Optoisolator IC 6-pin in Egypt?
4N25S SMD Optocoupler Optoisolator IC 6-pin currently costs 20.52 EGP in Egypt.
Where can I buy 4N25S SMD Optocoupler Optoisolator IC 6-pin in Egypt?
4N25S SMD Optocoupler Optoisolator IC 6-pin is available from UGE. Compare the offers above to find the best price.
How do I drive the input side?
Use a series resistor to set the LED current, sized from the forward current in the datasheet and your supply voltage.
Can it be used as a digital switch?
Yes. The phototransistor output can switch a load or pass logic signals across the isolation barrier, typically with a pull-up or load resistor on the output side.
