Optoisolators - Transistor, Photovoltaic Output

Optoisolators are a form of signal isolation which allows for an input signal to be transferred and isolated from an input circuit to an output circuit without any electrical contact between them. A common example of an optoisolator is the 6N139M general purpose high speed optocoupler, which is used in a variety of applications such as motor control, DC/DC converters, and modems. In this article we will discuss the application field and working principle of the 6N139M optoisolator.The 6N139M is a high-speed optocoupler that provides galvanic isolation and high common-mode noise immunity. It consists of an infrared LED (emitter) and a photodetector (output) coupled by an optically opaque plastic envelope, and is available with a variety of package formats. The 6N139M is widely used in power electronics for controlling AC loads, such as switching regulators, AC motor drives, and other industrial motor control applications. The device can provide isolation between input and output up to 5000V DC, enabling it to withstand harsh industrial environments.In addition to the electrical isolation, the 6N139M optocoupler also provides optical isolation to reduce the effect of noise coupling between input and output circuits, which is much preferable in data transfer applications. The device is also used in telecommunication systems and sensor circuits for isolating signals from a high-voltage environment while still providing very fast response time.The 6N139M operates based on the photovoltaic effect, where incident light is converted into electrical energy. When the light from the infrared LED is received by the photodetector, it produces a photocurrent proportional to the brightness of the light. This photocurrent is then converted into an electrical voltage, and is used to control the output of the optocoupler.The 6N139M optoisolator has a wide range of applications, from motor control and high voltage signal transmission to data transfer and sensor circuits. Its high isolation and fast response time make it a preferred choice for applications that require reliable signal transmission in harsh environments. Furthermore, its compact form factor and low cost make it a suitable solution for many consumer and industrial applications.In summary, the 6N139M optoisolator is a versatile and reliable device that is widely used in applications that require fast and reliable signal transmission with high isolation. It is relatively easy to use and its small size and low cost make it an ideal solution for a wide range of applications. The 6N139M optoisolator is a reliable and valuable tool that can be used to provide electrical and optical isolation in any application, making it the ideal choice for many industrial and consumer applications.
