Optoisolators - Transistor, Photovoltaic Output

Opto-isolators, also referred to as optical isolators or opto-couplers, are used to electrically isolate two circuits. They are useful in electric and electronic circuits to protect areas of the circuit from electromagnetic interference as they prevent signals from one circuit affecting another. In industrial applications, they are used to provide electrical safety and prevent equipment or device malfunctions due to faulty electrical signals. The CNY17F-2X017 opto-isolator is a surface mount optically coupled isolation device, with a phototransistor output and built in flyback diode, designed for use in low voltage, high frequency isolation. The opto-isolator encapsulates two closely spaced LED’s and a photoreceptor in an epoxy package. The LED transmits light onto the phototransistor and the light produced by the LED is amplified by the phototransistor, allowing signals from one circuit to influence the other without electrical contact. The working principle of the CNY17F-2X017 opto-isolator is based on three critical parameters, the response speed, the response time and the optical transmission. The response speed is the amount of time it takes for the LED to respond to the input signal and the response time is the amount of time it takes for the phototransistor to turn on. The response speed and response time depend upon the distance between the LED and phototransistor, as well as the capacitance of the circuit. The optical transmission is a measure of the light transmission between the two components, affected by the size and material of the LED and the phototransistor. The CNY17F-2X017 opto-isolator has a wide range of applications including:

• Robotics – providing safety and motion control for robots
• Automotive systems – providing safety to control systems
• Telecommunications – providing electrical isolation for communications equipment
• Medical equipment – providing electrical isolation for medical lab equipment
• Low-voltage circuits – providing electrical isolation for low- voltage circuits

The CNY17F-2X017 opto-isolator is a single component device that requires little space to install, runs at a low voltage and operates at high frequency. The optoisolator is used to electrically isolate two circuits, preventing signals from one circuit affecting the other. The phototransistor output enables signals from one circuit to influence the other and the built-in fly-back diode prevents damage due to reverse voltage. The CNY17F-2X017 optoisolator is highly dependable and reliable for a wide range of applications.
