LITEON Technology MOC3083M Environmental and export classification status description

of Onsemi MOC3083M The MOC3083M is an optoisolator that contains a gallium arsenide (GaAs) infrared emitting diode and a phototransistor in a single package. This component is used to provide electrical isolation between input and output circuits, allowing for communication without direct electrical connection, which is particularly important for protecting sensitive components from high voltage surges. Functions 1. Electrical Isolation: Provides high voltage isolation between input and output, typically around 5kV. 2. Signal Transmission: Facilitates the transfer of signals between different areas of a system, enabling communication without direct connection. 3. Control Applications: Commonly used in driving loads such as relays, or interfacing microcontrollers with AC devices. 4. Safety: Protects low-voltage circuits from high-voltage spikes and failures. Applications 1. AC Load Switching: Used to control AC loads with low-voltage control signals. 2. Telecommunications: Provides safety and integrity in communications systems by isolating different parts of the system. 3. Industrial Automation: Interfaces sensors and controllers in automated systems. 4. Power Supply: Used in switch-mode power supplies for voltage feedback and control. Alternative Parts 1. MOC3063: A similar optoisolator with a different input-output voltage capability. 2. MOC3021: Another optoisolator that can handle lower power applications. 3. PC817: A widely used optoisolator with different isolation and voltage characteristics. 4. TLP series (Toshiba): Various models providing similar isolation and control features. Embedded Modules - Isolation Modules: Modules that incorporate the MOC3083M for easy integration into designs requiring optoisolation. - Microcontroller Interface Boards: Boards designed for integrating microcontrollers with hazardous voltage environments using the MOC3083M.
