Optoisolators, sometimes referred to as optical couplers, are devices that use an infrared (IR) light emitting diode (LED) to optically isolate a signal from one point in a circuit to another point in the same or different circuit. The PS8501L3-E3-AX is an optoisolator of the transistor, photovoltaic output type. In such optoisolators, the LED is used to detect changes in the signal, while the photovoltaic output (typically a photodiode) is used to generate the output signal.

The application fields of the PS8501L3-E3-AX optoisolator cover a wide range of uses, including signal conditioning, industrial and safety control systems, electrical protection and monitoring, instrument control, rail transport systems and lighting control. This device is also used for power switching applications, providing a fast response time, high voltage protection and insulation requirements of automotive systems. In addition, this device also has superior immunity to electro-magnetic disturbance and can be used for automotive applications with its wide temperature range characteristic.

The working principle of the PS8501L3-E3-AX optoisolator is based on a transistor-integrated LED and photodiode coupled together to form a closed loop. When the voltage across the LED increases, the current flowing through the LED increases and the output current of the photodiode also increases correspondingly. As the output current increases, the voltage at the photodiode\'s output is also increased, resulting in the optoisolator functioning as a voltage amplifier.

The transistor integrated into the PS8501L3-E3-AX optoisolator ensures the output current is stable and provides a high-voltage protection capability by limiting the output voltage. The high insulation characteristics of this type of optoisolator also prevents potential damages from external noise and precise peripheral components. Additionally, this device is designed to scale the output voltage for improved signal detection.
