Optoisolators are devices that provide isolation between two circuits, usually referred to as an input and output. They can be used in a variety of applications, such as signal transmission, power switching, motor control, and many others. The MOC8107SD is a dual-channel optoisolator with both transistor and photovoltaic outputs.

MOC8107SD Application Fields

The MOC8107SD can be used in various applications, depending on its output type. With its transistor output configuration, the optoisolator is typically used in controlling loads that require higher current than the optoisolator itself can provide, such as motors, relays, or solenoids. The photovoltaic output configuration is usually used for applications which require higher voltage levels than the optoisolator’s supply, and even AC voltage or momentary power sources.

MOC8107SD Working Principle

The MOC8107SD works through the use of a light-activated switch and a transistor or photovoltaic output. In its basic operation, the optoisolator includes an infrared LED that is illuminated when a current is input to the transistor and photovoltaic outputs. This light then activates a phototransistor, which acts as a switch and completes the circuit, allowing the current output from the optoisolator.

In the transistor output configuration, the optoisolator uses the current output from the phototransistor to switch the current flow in the output circuit, giving the user the ability to control a load with a higher current than the optoisolator’s supply. In the photovoltaic output configuration, the optoisolator uses the current output from the phototransistor to drive the output circuit, allowing it to provide higher voltages than the supply voltage of the optoisolator.

The MOC8107SD optoisolator is a great choice for a range of applications that require isolation between input and output signals. Its transistor output option is great for controlling higher current loads, while its photovoltaic output configuration makes it an excellent choice for applications that require higher voltages.
