About this product
The 4N35 is a general-purpose optocoupler that pairs a gallium-arsenide infrared LED with a silicon NPN phototransistor in a 6-pin DIP package. It passes a signal between two circuits optically, so they share no direct electrical connection and a fault on one side is less likely to damage the other. It is commonly used to isolate microcontrollers from higher-voltage circuits.

Frequently asked questions
What is the price of 4N35 General Purpose Optocoupler Phototransistor DIP-6 in Egypt?
4N35 General Purpose Optocoupler Phototransistor DIP-6 currently costs between 6.9 and 17.1 EGP across 5 offers in Egypt.
Where can I buy 4N35 General Purpose Optocoupler Phototransistor DIP-6 in Egypt?
4N35 General Purpose Optocoupler Phototransistor DIP-6 is available from Most Electronics, Microohm, Circuits Electronics, Makers Electronics, and UGE. Compare the offers above to find the best price.
How do I wire the 4N35?
Pins 1 (anode) and 2 (cathode) drive the internal LED, so put a series resistor on the input side to limit its current. On the output, pin 5 is the collector and pin 4 is the emitter. Pull the collector up through a resistor and read the signal there.
Can the 4N35 switch mains voltage directly?
No. It is a signal isolator with a low-current phototransistor output. To switch a heavier load, drive a transistor or relay from its output.
