Optoisolators - Transistor, Photovoltaic Output

Optoisolators are a type of isolator used to isolate two circuits from one another, usually to provide electrical isolation and/or to prevent operating faults from propagating to sensitive components. The most common type of optoisolator is the transistor, photovoltaic output (MOC81073SD) which consists of an LED, a photodiode, and a Darlington phototransistor. When an electrical signal is applied to the LED, it emits light which is converted by the photodiode into a small amount of current. This current is amplified by the Darlington phototransistor and used to control the base current of an external transistor, allowing the isolated circuit to be electrically switched.The MOC81073SD is an optically-coupled transistor/photovoltaic output device, designed for applications requiring electrical isolation. Its LED and NPN phototransistor are isolated from each other, meaning that the LED and transistor are not mechanically connected.This type of optoisolator is suitable for use in many electronic circuits, such as industrial control automation, embedded systems, analog signal processing and process control. It is a bidirectional device, meaning that it can be used both to turn circuit elements on and off. It is optimized for switching solid-state relays, solenoids, motors, lamps and other circuits, and is also widely used as an interface between a signal source and controller. The MOC81073SD is designed to provide a high level of insulation between input and output circuits. Electrical isolation of up to 6KV peak is provided between its LED and phototransistor, and all circuits are isolated from the control voltage. This ensures that the input and output do not interfere with one another, and protects sensitive components from damage due to power surges or electrical shorts. In addition, the MOC81073SD has a low current draw and does not require a separate power supply. It has a wide range of input voltage from 3 to 24V DC, and its LED is driven by a constant current source to ensure its operation is unaffected by variation in the input voltage. The device also has a low I/O leakage current of less than 2nA, making it suitable for sensitive applications.Overall, the MOC81073SD optoisolator is an excellent choice for applications requiring high levels of electrical isolation between circuits, particularly in industrial control and embedded systems. It is easy to install and use and has a range of features that make it a very attractive choice for designers.
