Optoisolators are a type of electronic component which use a combination of light and electronics to isolate components from one another. The 4N55/883B#200 is an optoisolator that is a transistor photovoltaic output, and is widely used for various applications. In this article, we will discuss the features of the 4N55/883B#200, as well as its application fields and working principle.

Features of the 4N55/883B#200: The 4N55/883B#200 is a general-purpose optoisolator, meaning it is suitable for a wide variety of applications. It is an integrated circuit package which contains both an infrared emitting diode and a photosensitive transistor array. The device has a standard current transfer ratio (CTR) of around 0.7A/W, with a minimum of 0.5A/W and a maximum of 1A/W. Its output collector-emitter saturation voltage is typically 2V, with a maximum of 4V. The 4N55/883B#200 also has a high speed response rate, typically between 150ns and 500ns. Other features include its low power consumption and its compact size, which make it easy to use and install.

Application Fields of the 4N55/883B#200: The 4N55/883B#200 can be used in a variety of applications, such as in motor control systems, navigation systems, security systems, audio equipment, and data communication systems. It is also widely used in industrial control systems, such as in sensors, actuators, switches, and relays. The optoisolator is often used in control systems which require reliability, as it effectively eliminates EMI/RFI interference.

Working Principle of the 4N55/883B#200: The 4N55/883B#200 is a photovoltaic output optoisolator, which means it uses photon-induced voltages to generate electrical signals. As light is transmitted from the LED to the photodiode, electrons are transferred from the LED to the diode, creating a reverse-biased potential between the diode and the transistor. When the diode\'s potential reaches a certain threshold, a current is created which causes a collector to emit from the transistor. This current is then used to control various components, such as relays, motors, and sensors. The 4N55/883B#200 is a 4-pack optoisolator, meaning it can be used to control up to 4 different components.

In summary, the 4N55/883B#200 is a widely used general-purpose optoisolator with features such as high speed response, low power consumption, and a standard current transfer ratio of 0.7A/W. The device has a range of application fields, such as motor control, navigation systems, and industrial control. Finally, the optoisolator works by using photon-induced voltages to generate electrical signals which control components such as relays, sensors, and motors.
