The PC123F2J000F is an optoisolator in the Transistor, Photovoltaic Output family. This component is designed to provide galvanic isolation from a source to a separate circuit without the need for an external power supply, allowing for low power consumption during the signal transmission. This makes it ideal for applications that require reliable and accurate data transmission.

Application Fields

The PC123F2J000F is used in a variety of applications, such as:

• Safety and fault protection circuits
• PC/PLC communication lines
• High-power switching circuits
• Remote data acquisition systems
• Building automation systems
• Solar cell monitoring systems
• Industrial sensors and control systems

The optoisolator’s robust design makes it an ideal choice for harsh industrial and outdoor environments, where it can perform reliably in temperatures ranging from -30°C to +70°C.

Working Principle

The optoisolator is composed of two different parts: an input stage and an output stage. When the input signal is applied to the input side, it activates an LED, which sends a light signal to a photo-transistor on the output side. The photo-transistor then amplifies the signal and sends it to a connected circuit.

In this way, the optoisolator creates an electrical barrier between the input and output, which isolates the two circuits electrically while still allowing a connection between them. This ensures that the transmitted signal does not suffer from any external interference or signal degradation.

The PC123F2J000F is also designed with a low power consumption, making it suitable for applications with limited supply voltage. Its maximum operating voltage is 3.75V, and the maximum input current is up to 100mA.

Conclusion

The PC123F2J000F optoisolator is an ideal choice for applications requiring reliable and accurate signal transmission in harsh environments. Its low power consumption makes it suitable for applications with limited supply voltage, while its robust design ensures that it can withstand extreme temperatures. By creating an electrical barrier between the input and output, it isolates two circuits while still allowing a signal connection between them.
