CNY17F2SR2VM Isolators

Optoisolators - Transistor, Photovoltaic Output, like CNY17F2SR2VM, allow two circuits to communicate while still maintaining their complete electrical isolation. An internal LED transmits light signals to an integrated photodetector, allowing electrical isolation between power sources or user-accessible electrical sections. This type of optoisolator can be used to switch between power buses or provide separation between input and output signals in the conversion of analog or digital signals.

CNY17F2SR2VM is one type of optoisolator among Transistor, Photovoltaic Output, which is specially designed with a high voltage insulation capability of up to 5kV. When input voltage ranges from 8V to 30V, the LED current is set to a stable and reproducible level so that the photodetector can keep a stable current output.

An important feature of this optoisolator is its very low power consumption. As LED current source is integrated inside the device, user only needs a minimum driving power to light up the LED. It has a maximum current sinking of 50mAp-p thus making it ideal for low load capacity demand. It is also able to ensure a low-noise isolation and maintains the best signal integrity, which is very suitable for industrial, professional or commercial applications where low power consumption and electrical isolation are both accompanied.

The working principle of CNY17F2SR2VM optoisolator is simple. Once the input voltage is applied to the LED anode, current starts to flow into the LED cathode and the light is produced accordingly. The generated light will reflect at the photo-detector and activate the isolator. The optical transmission across the interface produces changes in the emitter-collector capacitance of a phototransistor, which is amplified in its base-emitter circuit. As such, electrical signals can be transferred from one circuit to the output circuit without any direct electrical connection.

CNY17F2SR2VM are wide used in a variety of applications for their cost-effective, low energy and high-speed operation. For example, they are applied in various electronic instruments such as computer peripherals like modems, printers, mouse and keyboards, as well as in ultrasonic distance, high-resolution optical mouse and level shifting applications. They are also highly immune to electromagnetic interference and have excellent temperature stability, making them ideal for use in industrial and hazardous area installations.

In summary, optoisolators - Transistor, Photovoltaic Output, like CNY17F2SR2VM, provide a useful isolation between two circuits. While it requires a minimum operating voltage and power, it has a very good and long-term stability. As such, it is widely used in various industries to provide safer, more reliable and energy efficient operation.
