Optoisolators - Transistor, Photovoltaic Output

Optoisolators are used in many different types of electronic products to isolate one part of a circuit from another or for common mode noise rejection. In this article, we will discuss the application field and working principle of a type of optoisolator – the CNY17-1-500E Transistor, Photovoltaic Output Optoisolator.

Application Field

The CNY17-1-500E Optoisolator is often used for on-off control circuits, ignition systems, and other automotive applications. It can also be used in industrial applications such as fieldbus and power supply control. It can also be used in electronic equipment to provide line or power isolation, motor drive control, and as a switch in audio or video equipment.

Working Principle

The CNY17-1-500E Transistor, Photovoltaic Output Optoisolator works by using an infrared LED connected to a transistor. When a current is applied to the LED, it gives off infrared light which is received by the transistor. This causes the transistor to turn on, allowing current flow from collector to emitter.The output current is determined by the amount of light being received by the transistor, and this is then converted into an electrical signal. The output voltage is also proportional to the amount of light it is receiving. The current output of the device is limited to 20mA and the voltage to 500V max, making it well-suited for use in automotive applications.

Advantages

The CNY17-1-500E Optoisolator has many advantages over traditional transistor-based circuits. One advantage is that it is fully integrated, which means there is no need for wiring or external components, which can save time and cost in the production process.It also has excellent common mode noise rejection, meaning it is difficult for noise to affect the circuit. This makes it a good choice for automotive and other sensitive industrial applications where noise is a major issue.Finally, the CNY17-1-500E Optoisolator is small and lightweight, which makes it easy to use and adapt into a variety of applications.

Disadvantages

The main disadvantage of the CNY17-1-500E Optoisolator is that it is not very efficient. It requires a lot of current to operate, which can lead to overheating. This can be a problem in applications where space is limited and the device needs to be exposed to higher temperatures.The input voltage also needs to be kept within the device’s limits, and any voltage fluctuation can cause the output to fail. This can be a problem in applications where the input voltage is not stable.

Conclusion

The CNY17-1-500E Transistor, Photovoltaic Output Optoisolator is a popular device for its compact size, low cost, and excellent noise rejection. However, it can be inefficient and vulnerable to voltage fluctuations, so it is important to ensure that the input voltage is kept within the device’s limits. In applications where noise is a major issue, this optoisolator can provide reliable isolation.
