Optoisolators, also called optical couplers or photocouplers, are electrical insulators with photoelectric conversion capability that effectively transfer electrical signals from adjacent circuits, while keeping them optically isolated. The optoisolator, MOC8106M is a 6-pin, 600V, ultra low-capacitance, AC input optoisolator, housed in a Mini-FLAT package with a transistor output. It is designed to provide an extremely fast, reliable, and isolated method for detecting low-level signals.

Features of MOC8106M

The MOC8106M features a high speed response time of 3us, an off-state output voltage of -3V, a load capability of 15mA, and a maximum pulse width of 800ns. It is also equipped with an LED indicator, which is a visible warning for power to the optoisolator. The operating temperature range of MOC8106M is from -40C to +85C. It has a common anode input, and a current transfer ratio of 2.

Application Field of MOC8106M

MOC8106M is widely used in communication and control interface applications. It can be used for signal transmission between remote locations, such as gateways, routers, Wi-Fi access points, and switches. It can be used to transfer data between microcontrollers and field sensors. It is also used in industrial automation, such as PLCs, as well as robots and CNC machines. MOC8106M can also be used in medical diagnostic equipment, military equipment, consumer electronics, and automotive applications.

Working Principle of MOC8106M

MOC8106M employs a method of photoelectric conversion to transmit electrical signals from one circuit to another without direct electrical contact. It uses an LED and a photodetector to convert an electrical input signal into an optical signal, and then converts the optical signal back into an electrical output signal. The LED emits light when an input voltage is applied to it. The light is then detected by the photodetector, which in turn produces an electrical current, which is then amplified by the phototransistor. The output voltage is then obtained at the emitter terminal of the optoisolator.

The optoisolator ensures electrical isolation between the input and output signals. This isolation makes the optoisolator ideal for applications requiring signal isolation between circuits with different ground potentials. It also makes the optoisolator suitable for applications requiring long-distance signal transmission, since the electrical insulation provided by the optoisolator ensures that the signal remains unaffected by external electrical interference.

Conclusion

The MOC8106M is an optoisolator designed to provide fast, reliable, and isolated signal transfer. It is widely used in communication and control interface applications, industrial automation, military technology, consumer electronics, medical diagnostics, and automotive applications. It features a high speed response time, an off-state output voltage of -3V, a load capability of 15mA, a maximum pulse width of 800ns, and an LED indicator. The optoisolator works by converting an electrical input signal into an optical signal, which is then detected by a photodetector and amplified by a phototransistor, producing an electrical output signal.
