The Optoisolators - Transistor, Photovoltaic Output series, designated as PS8101-F3-AX attain electrical isolation between an input control voltage and an output load voltage. This product family features a photovoltaic device enclosed within an insulated housing. This optoelectronic component includes a photosensitive detector and an output transistor. This configuration allows the device to provide a reliable and straightforward electrical barrier between two separate circuits or sub systems without ensuring any direct electrical contact between them.

Application fields
Optoisolators - Transistor, Photovoltaic Output are ideal for use in a wide range of applications – from automobiles, power supplies, motion control and instrumentation to telecommunications. In general, they are employed in situations that require electrical isolation between the input and output. This offers several advantages, such as a noise-free transmission between sub-systems, improved accuracy and reliability, and enhanced safety.

Working principle
The PS8101-F3-AX optoisolator comprises of a photovoltaic detector which is constructed by connecting several photovoltaic cells in the form of a transistor. This device absorbs the light energy from a photodiode directly to generate voltage. The absorbed light energises the detector which causes it to emit a small amount of currrent which in turn is used to activate a power transistor on the output side of the device.The optoisolator is optically isolated, meaning that the detector behaves as an ideal insulator and the waves of the signal radiation from the input side are essentially completely blocked, blocking any direct current flow from the input to the output. In the PS8101-F3-AX, the internal isolation forms an ideal and secure electrical barrier between the input and output. The device works on the principle of electro-optic modulation, wherein the incoming signal at the input side, is converted into a modulated optical signal and is then transmitted to the other side and reconverted to electrical waveform. As in the input side, the radiation is blocked completely, the optical isolation helps to fully isolate the two parts of the optoisolator. Additionally, this particular type of optoisolator also provides transistors on both sides, making it suitable for switching current and voltage levels from the input to the output.

The optoisolator also employs an internal transistor to amplify the photo current, which is generated by the radiation. The amplification and the isolation make the optoisolator suitable for use in applications where high-speed switching is necessary, such as safety-protected circuits and industrial automation.

The optoisolator features low power consumption and low noise operational characteristics, making it a reliable choice for several applications. Its compact size and low voltage ratings allow it to fit into tight spaces, while its compatible pin configuration enables easy installation. Overall, the PS8101-F3-AX series provides an excellent combination of features, making it an ideal solution for a variety of applications.

In conclusion, the PS8101-F3-AX optoisolator series is ideal for use in various applications requiring electrical isolation between the input and output. It provides a reliable barrier, enhanced safety, reduced noise level, low power consumption, and a compact size. This all-in-one optoisolator ensures superior performance in a wide range of applications and provides an economical solution for system designers.
