Optoisolators - Transistor, Photovoltaic OutputAn opto-isolator, also known as an optically coupled isolator or an opto-coupler, is an electrical device designed to provide isolation between two electrically isolated circuits. It typically provides insulation of 1-2 kilovolts, making it useful in eliminating electrical noise, preventing interference between components, and preventing overloads from damaging sensitive electronics. The 6N139-320E is a type of opto-isolator called a Transistor, Photovoltaic Output (TPO). It is designed to allow for digital communication and signal transmission between circuits. The 6N139-320E is composed of an LED that is mounted on a circuit board and connected to the power and ground lines. The LED emits light when an input current is applied, which is then detected on the output side of the device. The output side of the device consists of a photodiode which is sensitive to light. When the LED emits light, the photodiode produces a small current, which is then used to switch on a solid-state switch. The switch is usually connected to a transistor, allowing the output signal to be sent across the isolated section of the circuit.The 6N139-320E opto-isolator has a number of advantages. The most notable of these is its immunity from electrical noise and interference caused by nearby power sources or other electrical components. This makes it especially suitable for use in places where power supplies may not be completely reliable or might cause interference with other components of the same circuit. Additionally, the 6N139-320E is designed to be very low power, allowing it to be used in a variety of applications without needing complicated power supplies. And due to its small size and low weight, it is an ideal option for applications where space and/or weight is at a premium.The 6N139-320E can be used in a wide variety of applications, including for interfacing with sensors, for communicating with microcontrollers, for controlling them from external systems, for motor control, and other applications where reliable signal transmission is necessary. Additionally, it is often used in industrial applications where reliable signal transmission between multiple circuits is important. The 6N139-320E can be used for both digital and analog systems.The 6N139-320E is based on a simple photovoltaic principle. The primary function of the 6N139-320E is to convert light energy into electrical energy. The photodiode on the output side of the device detects light, which is then converted to electrical energy. The electrical energy is then sent across the isolated section of the circuit, allowing for signal transmission without being affected by any external voltage. Additionally, the 6N139-320E makes use of an optocoupler, which provides further insulation between input and output circuits.To sum up, the 6N139-320E is an opto-isolator based on photovoltaic principle. It is capable of providing galvanic isolation between two circuits, allowing for reliable signal transmission. The optocoupler and low power design also make it ideal for applications where reliable communication, low power consumption, and/or slim design are necessary. It is useful for a variety of applications from interfacing with sensors and controlling motors, to communicating with microcontrollers and other external systems.
