Optoisolators are electronic components used in electronic systems to provide electrical isolation between two circuits. One of the most popular optoisolators is the VOM618A-5T, which employs a transistor coupled with a photovoltaic device to isolate an input from an output. Its application field and working principle is outlined below.
Application Field
The primary application field for the VOM618A-5T optoisolator is in providing electrical isolation between circuits with different voltages. The optoisolator is designed to prevent voltage surges and spikes from impacting the input circuitry, as well as protecting the output from electrical noise. The optoisolator can also be used for controlling higher voltage devices from a low voltage input. When the voltage on the input side exceeds certain thresholds, the photovoltaic device opens a transistor, which can be used to control other devices or circuits. This function is often used in products such as lighting controllers, power supplies, and safety systems.
Working Principle
The VOM618A-5T optoisolator consists of a photovoltaic device connected in parallel with a transistor. The photovoltaic cell is typically an infrared LED or a photodiode. When the current in the input terminal causes the infra-red LED to turn on, the photovoltaic device produces a voltage, which turns on the transistor. When the current on the input side increases beyond a certain level, the transistor opens and breaks the circuit on the output side. This prevents voltage spikes and surges from impacting the output and protecting sensitive circuitry. When the current on the input side drops again, the transistor closes and reconnects the output.
Conclusion
The VOM618A-5T optoisolator is a versatile and reliable device, capable of providing electrical isolation between two circuits with different voltages. Its primary uses are to protect sensitive circuitry from voltage surges or spikes, and to control higher voltage devices from a low voltage input. Understanding the working principle of the optoisolator is integral to using it in electronic systems.
