CNY17-3M Isolators

Optoisolators - Transistor, Photovoltaic Outputs are a type of optocouplers that employs a light emitting diode (LED) as the output element. They are used for signal isolation and data communication protection applications, such as digital-to-analog (DA) or digital-to-radiating (DA) interface. In order to ensure safe and reliable electrical isolation, the device uses an opto-coupler, which isolates the circuitry into two sections – an optical originator or transmitter and a photocopy or a receive. The CNY17-3M is an optoisolator with a photovoltaic output.

The CNY17-3M is specifically designed for communication applications that require data transmission rates up to 5 Mbits/s. The optoisolator offers electrical isolation up to 15kV. It is designed to take in the input signal level from TTL circuits. It contains a gallium arsenide (GaAs) photodiode that is able to absorb both monochromatic and other visible light in a wide range from 600 to 850 nanometers (nm), which helps it to detect the directly transmitted light. This device has a forward voltage threshold from 0.85 V to 1.25 V and a peak photocurrent of 200 μA.

The working principle of the CNY17-3M involves a light emitting diode (LED) emitter being optically coupled with the input line receiver, which is usually an amplifier. The input signal is first transmitted through the LED emitter, which produces light in the visible spectrum except for IR. This light is then detected by the presence of a photodiode receiver. The receiver induces a current based on the intensity of the light. The signal is then amplified and isolated from the input. This isolated signal is then transmitted as an output, allowing for safe and reliable transfer of digital signals.

The CNY17-3M is a relatively cost effective optoisolator compared to other optoisolators with similar specs. It is suitable for applications such as digital and radiation communication interfaces, PC and peripherals, audio and wireless equipment, and many other products. The optoisolator is designed to provide completely isolated data transmission, ensuring that the data and signals are secured and protected from the outside world. This is crucial in communication applications, as it prevents unwanted interference and signal loss.

In summary, the CNY17-3M optoisolator is a photovoltaic output optoisolator designed for communication applications that require data transmission rates up to 5 Mbits/s. It contains a gallium arsenide photodiode and has a forward voltage threshold from 0.85 V to 1.25 V and a peak photocurrent of 200 μA. The working principle involves a LED emitter being optically coupled with an amplifier. The light from the LED is then detected by the presence of a photodiode receiver. The signal is then amplified and isolated from the input before being transmitted as an output.
