4N36 Pinout

4N36 Pin Description

The 4N36 optocoupler is a general-purpose optocoupler. It comes in a 6 pin dip package as well as SMD packaging. It has two internal components, one of which is an IR LED and the other is a phototransistor. The 4N36 optocoupler functions in the same way as any other comparable optocoupler.

The 4N36 optocoupler can be used in a variety of applications, including protecting circuits from voltage spikes, creating isolation between two circuits, and detecting the presence of AC or DC current. It can also be utilized at the output of microcontrollers and other ICs with low output current so that high-current components, such as high-power transistors, can be operated with these ICs and microcontrollers.

It's as simple as using a regular LED and a phototransistor to use a 4N36 optocoupler. Connect the anode of the IR LED to the positive output of your component, which can be an IC or microcontroller, and the other pin (Cathode) to the negative or ground of that component to use the device. It is critical to use a current limiting resistor between the output of the IC or microcontroller and the anode of the IR LED.

When the phototransistor detects light from the IR LED, the collector and emitter pins will link, and anything connected to pins 4 and 5 will become connected as well. As previously stated, the phototransistor can be controlled by its other base, which is connected to pin 6, allowing the user to operate the transistor via its other base / pin6.
