Optoisolators, one of the most popular techniques utilized for electrical isolation, can be divided into two major categories which are transistor, photovoltaic output optoisolators and transformer output optoisolators. This article will discuss the application field and working principle of FOD852300W optoisolator, which falls into the category of the former type.

FOD852300W is a typical example of transistor, photovoltaic output optoisolator. It is comprised of an infrared emitting diode (IRED) positioned facing and optically coupled to a phototransistor. IRED is responsible for emitting light, while the phototransistor transforms the light signal into an electrical signal. Devices of this type can support bipolar signals, digital signals, as well as linear current signals.

FOD852300W is mainly used in various fields such as consumer electronics, powered shovels, welding machines, etc. It can be used to optically isolate signals and provide a secure insulation for both the input and output circuits. Additionally, since it is also able to support bipolar signals, it can even be used to create a circuit that utilizes range sensing to detect the presence of a particular object.

In order to understand how FOD852300W works, let us look into the working principle of the optoisolator. Essentially, it produces two opposite signals, one that is used for switching and the other for sensing. The optical radiation, usually in the infrared spectral range, emitted by the IRED is detected by the phototransistor. As a result, a voltage change is produced in the phototransistor and this is used as the input signal for the switching circuit.

When the voltage across the phototransistor’s collector and emitter rises, it produces an electrical signal that is used to switch on the associated circuit. Conversely, when the voltage falling across the phototransistor’s collector and emitter declines, the circuit is switched off. Additionally, the voltage across the phototransistor’s collector and emitter can also be used to measure the intensity of the light emitted by the IRED. This is an attribute that makes FOD852300W optoisolator to be able to measure the amount of current flow in an adjacent circuit.

Apart from switching circuits on and off, FOD852300W optoisolator can also be used to protect the circuits for both input and output from noise and interference. It operates by providing electrical isolation between the input and output circuits. As such, any interference generated at one end will not travel to the other end. This in turn prevents the interference from affecting the desired output.

In short, FOD852300W optoisolator is a component suitable for various applications in the fields of consumer electronics, powered shovels, welding machines, and many others. It provides isolation, switching, and measuring functions, which makes it an ideal choice for circuits that require reliable and secure electrical isolation.
