Optoisolators are special-purpose electrical components which are used to isolate voltages or currents between two components in a circuit. They are mainly used in industrial applications like motor control, motor drives, robotics and other power electronic systems. One of the most common type of optoisolator is the 6N139TVM Transistor, Photovoltaic Output. This particular optoisolator works on the same principle as other types, but offers higher current and voltage carrying capacity.

The 6N139TVM optoisolator consists of three parts: A photo-transistor, a photovoltaic cell and a reflective surface. It works by converting energy from the light emitted by the photovoltaic cell into electrical energy. The electrical energy is then passed through the photo-transistor which can switch between a low-power (non-conductive) and a high-power (conductive) state. This enables the optoisolator to safely isolate the input and output of a circuit. The reflective surface ensures that only the desired amount of light is used for the optoisolator’s operation.

6N139TVM optoisolators are mainly used in industrial applications, such as motor control and motor drives, where there are high voltage pulses or electric fields present. The optoisolator provides a controlled and isolated interface for these applications, enabling more reliable performance. For example, in a motor control system, the optoisolator can be used to control the pulse-width modulation (PWM) of an inductive motor. This can prevent the motor from going into runaway mode, thus improving the reliability of the system.

In addition to motor control, 6N139TVMs are also used in robotics and other power electronic systems. For example, it can be used as an interface between the robots’ controller and the motors, enabling a controlled and isolated communication. This ensures that the robots’ motion remains stable and accurate. Furthermore, it can be used in power electronic systems, such as UPS and solar power inverters, to isolate the input and output of the system.

The 6N139TVM optoisolator is a reliable and cost-effective solution for isolating voltage and current in industrial, robotics and power electronic applications. It is capable of handling high voltage pulses and electric fields and provides reliable isolation between the input and output components of a circuit. This makes it a great choice for most applications requiring electrical isolation.
