10pcs 4N35 Optocoupler

4N35 Optocouplers provides reliable electrical isolation between input and output circuits.

Each optocoupler consists of a gallium arsenide infrared emitting diode optically coupled to a silicon phototransistor, housed in a standard 6-pin DIP package.

Ideal for general-purpose applications, they offer a high current transfer ratio and are commonly used in power supply regulation, digital logic isolation, and noise reduction circuits.
