Optoisolators, also known as optocouplers, are components used in electrical systems to isolate a section between two sections of circuitry. The FOD817C3S is an optoisolator device with a transistor, photovoltaic output. It is used to provide electrical isolation between two components that are otherwise not electrically connected.

The FOD817C3S is a monolithic, bipin optoisolator with a photovoltaic output transistor. The device consists of a GaAsP LED and an integrated photovoltaic output transistor. The LED is connected in series with the photovoltaic diode, which is connected to the collector of the output transistor. The LED and photovoltaic components are encapsulated in a standard 8-pin DIP (dual in-line package).

The LED light emitted by the FOD817C3S is absorbed by the photovoltaic diode which produces a photocurrent proportional to the LED current. The photocurrent through the diode is then amplified by the output transistor thereby producing an output voltage (Vce) proportional to the LED current (Iled). The output voltage (Vce) is determined by the LED current through the photodiodes and the amplification provided by the output transistor.

The FOD817C3S can be used in a variety of applications. It is commonly used to isolate two sections of circuitry, such as a control circuit and a load circuit. It is also used in digital logic circuit applications, such as isolated logic level shifters. In addition, it can be used as a switch to turn on and off a line in a circuit, as well as for input and output isolation in motor control circuits. In each application, the FOD817C3S provides electrical isolation between controlling and controlled sections.

The FOD817C3S can also be used in analog circuits, such as sample and hold circuits or digital-to-analog converters. It is also suitable for use in digital circuits such as microprocessors and microcontrollers. The device’s output transistor can be used to provide a regulated output signal in applications such as analog-to-digital converters and digital signal processing.

The FOD817C3S is a reliable and cost-effective optoisolator with a wide range of applications. Its photovoltaic output transistor provides electrical isolation between two circuits and allows for very low power signal transmission. The device is easy to use and can be integrated into a variety of circuits. It is an ideal solution for circuit designers who need electrical isolation for their designs.
