What is an Optoisolator?
An optoisolator is a type of electronic device that distributes electrical energy from one circuit to another via a short optical transmission line while also providing electrical isolation between two circuits. An optoisolator is a device that allows high voltages to be transferred from one side of a circuit to the other without any direct electrical contact.

Using a light-emitting diode, the devices turn electrical energy into a beam of light, which is then directed towards a light sensor, such as a photodiode or phototransistor, which transforms the optical energy back into electrical energy. This isolates the two circuits, avoids voltage spikes, and reduces noise and interference caused by communication connections.


Optoisolators are commonly used in power supply, control, and monitoring systems, communications systems, and other systems to electrically connect one circuit portion to another while preventing direct contact and high voltages from impacting the lower voltage side.

Basic Operation of an Optoisolator
The voltage from the primary circuit is applied to the power source to generate a near-infrared light beam that travels over the closed channel until it strikes the photo sensor, which converts the optical energy to electrical energy. Because the LED and the phototransistor or photodiode are separated and have no direct electrical connection, the device isolates the two sections of a circuit while allowing electrical energy to be transferred from one section to the other.


The phototransistor begins conducting electricity when the light from the LED strikes it, depending on the state and duration of the light. The optoisolators come in a range of shapes and sizes, such as cylinders, rectangles, and other unusual shapes. These are intended to isolate higher voltages than optocoupler SMD and DIP packages can.

Optopcouplers and optoisolators are sometimes used interchangeably; however, optocouplers can take voltages up to roughly 5000V, while optoisolators can handle voltages higher than 5000V.
