Overview

Optoisolators are electrical components which provide an isolated connection between two circuits. They achieve this by using an optical component, such as an LED or photodiode, to couple two electronic circuits. MOC8105S is a type of optoisolators and belongs to the Transistor, Photovoltaic Output category. This device is not commonly used on its own, but instead works in combination with other components to create a power supply circuit.

MOC8105S Applications

MOC8105S has a wide range of applications. It is used for isolation and interference reduction in many applications. It is commonly used for:

• Isolation of sensitive signals from noisy environments in data communication systems;
• Isolation of low voltage signals from high voltage ones in industrial automation systems;
• Receiving infra-red signals in remote sensing systems;
• Protecting digital circuits from voltage spikes and electromagnetic interference.
• Providing isolation in power supplies to protect from outside power disturbances.

MOC8105S Working Principle

The MOC8105S operates using a transistor and a photovoltaic output. The internal transistor is a pnp type transistor and it is responsible for coupling the input and output circuits. When a voltage is applied to the input of the optoisolator, an LED is then activated which generates light in the visible spectrum. This light is then detected by a photodiode connected to the optoisolator’s output. The photodiode converts the light into a current which then activates the transistor. When the transistor is activated it provides a path for the current to flow from the input to the output of the optoisolator.

The optoisolator provides isolation between the input and output circuits. This means that the two circuits are connected but the electrical connection is completely isolated. This feature is important as it helps to reduce interference and ensures only the desired signals are transferred between the input and output circuits.

The MOC8105S is a reliable and efficient optoisolator. It is designed to provide a high level of isolation between the input and output circuits. It is used in a variety of applications ranging from data communication systems to power supplies. It is a cost-effective solution that provides electrical isolation and interference reduction.
