Optoisolators, also known as optocouplers, are a type of circuit element that is used to electrically isolate two circuits. They are essential in providing isolation for electronic circuits, in particular for ensuring safety in low-voltage applications and protecting against electrical noise. The CNY17-2-W60E is a specific type of optoisolator, a transistor with photovoltaic output.The CNY17-2-W60E is an optically-coupled silicon paired device with a phototransistor output. It comes in a 17-pin miniature plastic flat-pack that is well-suited to space sensitive applications, and it has a guaranteed creepage and clearance distance of 4.0 mm, making it suitable for isolation in low voltage or high-current applications.

The CNY17-2-W60E can support both digital and analog systems, and has been designed for consistent current transfer ratio over a wide range of temperatures. The phototransistor output has a collector-emitter voltage of 40 V and a maximum collector current of 200 mA, making it ideal for most electrically-isolated applications. It also offers an isolation voltage of 5300 VAC, making it suitable for use in high-voltage environments.

The CNY17-2-W60E works by using the photoelectric effect to transfer electrical signals from one side of an electrical isolation barrier to the other. A photoemitter, which is a light-emitting diode (LED), is used to generate light of a specific wavelength. The LED is connected to a phototransistor, which is a semiconductor device that can detect this light and convert it into an electrical current. The optoisolator includes both the LED and phototransistor along with other internal components and has been designed to ensure that the LED and the phototransistor are properly matched and have a long operational life.When a current is applied to the LED side of the device, it emits light of a specific wavelength. This light is detected by the phototransistor, which creates an electrical current in response. This current is then passed through the output side of the optoisolator, providing electrical isolation for the two circuits. This means that signals can be sent from one side to the other without any risk of electrical interference.

The reliability and accuracy of the CNY17-2-W60E optoisolator make it a suitable choice for many applications. It is commonly used in industrial automation systems, electronic control systems, electrical switch control, power electronic circuits, and various other areas where isolation is required. It is also very popular for use in safety-critical applications, as its design ensures consistent performance and reliable isolation even in harsh environments.

In summary, the CNY17-2-W60E transistor optoisolator with photovoltaic output is a reliable and accurate device that provides an effective isolation barrier between two electronic circuits, allowing signals to be safely transmitted from one side to the other. Its wide range of voltage and current ratings make it a suitable choice for many applications, particularly safety-critical systems. It is a cost-effective and reliable choice for electrical isolation in low-voltage and high-current applications.
