CNY17F-4X007T

Optoisolators (also referred to as optically isolated or optocouplers devices) are widely used in a variety of applications to provide electrical isolation to sensitive electronic equipment. The CNY17F-4X007T optoisolator is an isolated transistors photovoltaic output device, providing high level of input-output isolation without the need for external components.

Working Principle

The CNY17F-4X007T optoisolator consists of an LED and a phototransistor. The LED is an optically transmitting element, which is connected to the input circuit. When the input circuit is applied with an electrical pulse, the LED is excited and generates light. The light emitted through the LED is detected by the phototransistor, which responds to the light and causes a feedback signal to the output circuit. This feedback signal is then amplified by the transistors of the output circuit, and thus providing electrical isolation.

Application Field

The CNY17F-4X007T optoisolator is particularly suited for applications which require a high level of electrical isolation between input and output circuits. Such applications include:

• Computer and industrial systems
• Information processing applications
• Controlling/measuring applications
• Communication equipment and various other applications

The CNY17F-4X007T optoisolator is designed to provide protection against high voltage spikes, electro-magnetic fields, and power transients. Its working characteristics provide high level of electrical isolation (3000Vrms minimum) between the input and output circuits, ensuring that sensitive electronic equipment is adequately protected. Furthermore, the device features minimal power dissipation and fast response time (efficient switching speed up to 500ns).

In order to reduce the power dissipation, the CNY17F-4X007T optoisolator includes a built-in overvoltage protection function, which automatically shuts down the device if the input voltage exceeds the specified limit. In addition, the device comes with a low power-up consent current miniaturized form factor.

The CNY17F-4X007T optoisolator is the perfect choice for applications which require high level of electrical isolation between input and output circuits. It is a proven and reliable solution for increasing safety and efficiency of computer and industrial systems, information processing applications, controlling/measuring applications, and communication equipment.
