An optocoupler is an electronic component that transfers a signal between electrically isolated circuits by converting the input signal into light and detecting it at the output. It provides the galvanic isolation, noise separation, ground-loop prevention, and circuit protection required to exchange control signals without a direct electrical connection.

Optocoupler datasheets provide key information such as isolation voltage, current transfer ratio, LED forward current, collector-emitter voltage, switching time, output type, package information, and thermal or safety characteristics. Engineers use these documents to select optocoupler devices for galvanic isolation, feedback loops, microcontroller interfaces, AC switching, motor control, power supply circuits, and industrial control systems.
This category page helps users discover optocoupler components across different manufacturers and output types, while also supporting quick navigation to specific part number pages.
