Optoisolators – Transistor, Photovoltaic Output, is a type of signal isolation technology used for the transfer of analog and digital signals between two or more communication systems or circuits. It uses a combination of a light source such as an LED (light emitting diode), an optocoupler consisting of a photodiode or similar photocell for the conversion of the signal, and a transistor or other semiconductor device for amplification or switching. The PC123P optoisolator is a particular type of optoisolator that combines a photocell, photodiode and bipolar transistor output. This makes it suitable for use in applications that require a combination of electrical and optical isolation, such as in motor controllers, machinery, industrial automation and communications.

The PC123P optoisolator provides a signal isolation of 2500 volts meaning that it can isolate input signals from hostile environments such as EMI and RFI prone electronics. It also offers high-speed operation due to its low propagation delay, making it suitable for time-sensitive applications. It has a trigger LED current of 1.5mA and a collector LED current of 0.5mA for a total of 2.0mA. Its maximum collector emitter voltage is 30V and its maximum collector current is 100mA. The PC123P optoisolator can be used in either a normally-on or normally-off configuration.

The PC123P optoisolator provides three key benefits; it isolates the input signal, amplifies the signal and switches or enables the output, depending on whether it is configured in a normally-on or normally-off configuration. An input signal is received by the LED, where it is converted into light energy. This light energy is then captured by the photodiode, which converts it into an electric current. This current is then amplified and sent to the output transistor, which switches or enables the output signal based on the type of configuration. This makes the PC123P optoisolator ideal for applications requiring bidirectional signal transfer, low power consumption and/or low voltage operation.

The PC123P optoisolator is also designed for use in applications subject to extreme environmental conditions. It has a wide operating temperature range, allowing it to be used in industrial, automotive and fuel cell applications. In addition, the optoisolator is robust and has a long operating life, making it suitable for applications where it must function reliably at extreme temperatures for long periods of time. Furthermore, its design employs low-power and low-voltage consumption principles, both of which lead to less heat production and longer operating life.

The PC123P optoisolator is one of the most versatile and reliable optoisolator components currently available. It provides reliable signal isolation, high-speed operation, low power consumption and extended operating life, making it suitable for use in a variety of industrial and consumer applications. Furthermore, its rugged design allows for use in severe environmental conditions and it is designed for low power and low voltage consumption to help extend operating life and reduce power consumption. As such, the PC123P optoisolator is an effective and reliable signal isolation solution for a wide variety of applications.
