Optoisolators are electronic components used as electrical isolators. They enable the transfer of power and/or signals between two or more isolated circuits. Designed to prevent interference, and even potential catastrophic events if one circuit operates in error, optoisolators are widely used in sensitive control or communication systems such as in industrial control, medical, military, or automotive applications. Among these optoisolators, Transistor, Photovoltaic Output optoisolator is an widely used optoisolator. One example of such optoisolator is the FOD617CW.

The FOD617CW consists of an infrared LED optically coupled to an integrated circuit detector. The optically coupled device has insulation and interconnection between input and output sides. The FOD617CW is an integrated photo coupler utilizing dual phototransistors. It is designed for collection and electrical isolation of DC currents. It offers high reliability and speed and has wide range of applications such as power supply switching, motor control applications, solenoid drivers, and instrumentation use.

The FOD617CW\'s working principle is simple and efficient. The LED emits light when a current is passed through it. This light then activates the photo transistor which provides a path for signal or power transfer between two isolated circuits. As its signal transferred through light, it cannot be interfered by external signals. Moreover, the LED and the phototransistor are separated by a gallium-arsenide infrared emitting diode, which provides isolation up to 7500V RMS.

The FOD617CW has wide application fields. It can be used in various industrial control and instrumentation applications such as energy monitoring, motor, power supply switching, solenoid drivers and solar array controllers. Its excellent speed of 1µs maximum ON-OFF time allows accurate and reliable signal transfer in maximum compliance with the specified standard. Its high voltage peak and high voltage isolation are suitable for short-term overvoltage protection applications, which makes it a great choice for applications needing electrical isolation.

In conclusion, the FOD617CW is a great example of Transistor, Photovoltaic Output optoisolators. It is suitable for various industrial control and instrumentation applications due to its excellent speed, high voltage peak as well as high voltage isolation. Its working principle is simple and efficient, showing great potentials in electrical isolation.
