Optoisolators are semiconductor devices that provide electrical isolation between the input and output parts of a circuit. CNY17F-1S1(TA)-V is a type of optoisolator which is designed specifically for voltage supply and sensing applications. It is a combination of an infrared light emitting diode and an N-channel enhancement-mode MOSFET. It has two major parts: an input and an output part. By emitting light to trigger MOSFET in the output part, it isolates the input and output side of the circuit, providing electrical isolation and a non-contact switch function.

It is suitable for use in a wide range of temperatures between -55°C to +125°C.

CNY17F-1S1(TA)-V also has applications in sensing applications. It can be used to sense ground faults, current overloads, panel temperature, DC input/output power and PWM controls. It is widely used in solar panels and other high power wattage applications. It is also used in various automotive applications such as sunroof and pre-crash sensing systems.

CNY17F-1S1(TA)-V Working Principle

The CNY17F-1S1(TA)-V optoisolator is mainly composed of an infrared light emitting diode and an N-channel enhancement-mode MOSFET. The basic principle is that when a voltage is applied to the input side of the optoisolator, the LED will emit light, which will then trigger the MOSFET to turn on or off. This is what provides electrical isolation and switching of the circuit without direct contact between the input and output sides of the optoisolator.

When a voltage is applied to the input of the optoisolator, the LED will emit infrared light which will then be detected by the photodiode in the MOSFET. This will trigger the MOSFET to turn on, allowing the load to be powered by the voltage applied to the input side of the optoisolator. When the voltage is removed from the input, the LED will stop emitting light and the MOSFET will turn off, breaking the connection between the output and input of the optoisolator.

CNY17F-1S1(TA)-V optoisolator is a great choice for voltage supply and sensing applications due to its high efficiency and isolation performance. It provides full electrical isolation between the input and output of a circuit, making it an ideal choice for low voltage power systems and high power wattage applications. It is suitable for use in a wide range of temperatures between -55°C to +125°C, making it an extremely versatile component for many different applications.
