The 6N136SMT/R is an optoisolator, often referred to as a transistor-photovoltaic output (T-PV). These devices are made by attaching an infrared light-emitting diode (LED) to a light-sensitive transistor. The current supplied to the LED causes it to emit light, which is then detected and collected by the transistor. This forms the basis of the optoisolator device because it isolates the driving current from the output signal.

The 6N136SMT/R optoisolator is a surface-mount package and is available in either two separate elements or as a one-piece component. It consists of the LED light-emitting element on one side, and the photo-transistor on the other side. The LED is mounted on the input side and the transistor is on the output side, providing electrical isolation between the input and output. The photo-transistor output is typically in the form of an open-collector output, meaning that the output transistor pulls the output to the ground level when the LED is illuminated.

The 6N136SMT/R optoisolator has a wide range of applications. It can be used to transfer signals between two isolated circuits, and is often used in isolating voltage signals from primary to secondary circuits. It can also be used to establish an isolated connection between digital logic elements, such as sensors and controllers. It is often used as the interface between two systems that must remain electrically isolated, such as a computer and a user interface.

The 6N136SMT/R optoisolator also has many safety applications. By isolating two circuits, it protects the control system from any inadvertent short circuits or voltage spikes that could otherwise cause damage to the system. They are often used in medical, industrial, and commercial applications, as they provide safety against potential electric shock hazards. It also helps to protect against current overloads, which can damage components or cause injury.

The working principle of the 6N136SMT/R optoisolator device is quite simple. When the LED is illuminated by the input current, it emits light, which is detected and collected by the receiver transistor. This light is converted to a voltage, which is then sent to the output. Depending on the type of optoisolator, the output can be either analog or digital. For the 6N136SMT/R, the output is typically low active and follows the LED input, so that the output is off or on depending on the input.

In summary, the 6N136SMT/R optoisolator is a transistor-photovoltaic output device that provides an isolated connection between two circuits. It is used to transfer signals between two isolated circuits safely and accurately, and is used in a variety of safety and industrial applications. The working principle of the 6N136SMT/R optoisolator involves the LED emitting light, which is detected and converted to a voltage at the output. Thanks to its small size and efficient design, the 6N136SMT/R optoisolator is an effective solution for many applications.
