6N134#100

Optoisolators, also known as optoelectronic isolators, are one of the most commonly used devices for electrical isolation due to their cost-effective and reliable design. The 6N134#100 optoisolator is a very popular example of a logic output optoisolator. This article will discuss the application fields and working principle of the 6N134#100.

Application Fields

The 6N134#100 is mainly used in applications where electrical isolation is needed between circuits, components, or systems. It is often used in communication systems, motor controllers, power supplies, inverters, and automation applications. It is also one of the most commonly used optoisolators for providing electrical isolation for computers and digital electronics.

The 6N134#100 has a wide range of applications due to its simple construction and low cost. It is often used in high voltage systems where its electrical isolation capability is beneficial. It is also used in many medical devices such as defibrillators and cardiovascular monitors.

Working Principle

At the core of the 6N134#100 is an LED and a phototransistor. The LED is powered by an external voltage source, while the phototransistor is connected to the load. The LED emits light when it is powered, which is picked up by the phototransistor and converted into an electrical current. This current is then supplied to the load, providing electrical isolation from the voltage source.

The optoisolator can be used with a variety of different components. The LED can be replaced with a photodiode or a laser diode. The phototransistor can also be replaced with a photodiode, a photovoltaic cell, or a photocell. Depending on the application, a bi-directional or uni-directional LED can be used.

To ensure electrical isolation between the voltage source and the load, the LED and the phototransistor in the 6N134#100 must be kept at least one millimeter apart. This prevents any electrical current from being conducted through the air gap between them. The optoisolator also has safety features to protect against overvoltage and short circuits.

Conclusion

The 6N134#100 optoisolator is one of the most commonly used optoisolators for providing electrical isolation between circuits, components, and systems. It has a simple design and is relatively inexpensive, making it suitable for a wide range of applications. The working principle of the 6N134#100 is based on an LED and a phototransistor, which separates the voltage source and the load. Safety measures must also be taken to ensure a safe electrical connection.
