4N35 is an optocoupler integrated circuit in which an infrared emitter diode drives a phototransistor. They are also known as optoisolators since they separate two circuits optically. These are used to couple two circuits without any ohmic contact.
Features
DC Voltage isolation: 5000Vrms
current: 50mA
Installation type: straight plug
Power: 70mW
