Optoisolators - Transistor, Photovoltaic Output provide higher output signal strength, status feedback and better hfe (current gain) than their counterparts with photocouplers, making them especially suited for driving relays, motors, digital Integrated Circuits (ICs) and other applications requiring high power outputs. The CNY17F-2S(TB) optoisolator is a perfect example of the strong output optoisolator available on the market today. This article will explore the application fields and working principle of this device.

The CNY17F-2S(TB) optoisolator is designed for analog inputs and TTL logic-level outputs. It can be used in digital filter outputs and to drive high-side transistor switches, as well as for pulse width modulation (PWM) applications. With its high input to output isolation capability of 13.3kV, it is a great choice for applications where safety and electrical isolation are prioritized.

This optoisolator is packaged in a compact SOT-88 molded package, making it ideal for high-density PCB circuit board designs. It is also RoHS compliant, making it environmentally friendly and cost effective. The optoisolator offers a wide operating temperature range from -40 to 105°C, making it well suited for use in an industrial setting.

The CNY17F-2S(TB) optoisolator features a full-bridge transistor output to LSTTL level, providing a higher drive current than its photo-transistor outputs. Its high input current of 10mA and higher output current of 250mA also provide an enhanced current drive capability, enabling reliable operation in harsh operating environments.

The optoisolator works by using a photodiode and a pair of light emitting diodes (LEDs). The photodiode receives the input signal which is turned into an electronic signal by the LEDs, which then passes through an optical isolation barrier and is received by the photodiode. The optoisolator then amplifies the signal and sends it to the output.

In addition to its optoisolator components, the CNY17F-2S(TB) also offers a variety of features that support a wide range of isolation applications. This includes a low forward voltage drop, a wide common-mode transient immunity, an optimized input-to-output skew, and a fast switching time.

The optoisolator also features a short-circuit protection circuit that prevents damage to the device in the event of an overload. Furthermore, the package is designed to reduce the need for external components, which helps to maintain a compact design.

Overall, the CNY17F-2S(TB) optoisolator is an excellent choice for applications where isolation is required and a high output current is needed. It offers a wide selection of features and support that make it suitable for a variety of applications. With its high input to output isolation capabilities and its ability to be used in PWM applications, it is the perfect optoisolator for any application.
