Optoisolators - Transistor, Photovoltaic Output

The PS2911-1-V-F3-L-AX optoisolator device is a photonically isolated device that combines a photodarlington emitter, a phototransistor and a LED built into a 6-pin SOP package. This device is a great choice for applications that require low compatibility, low power, high efficiency, and electrical isolation.

Application Field

The PS2911-1-V-F3-L-AX optoisolator is primarily used as an interfacing device for isolating floating or sensitive circuits from the logic or control system. This device is often used in circuits with either high or low voltage motors, generators, process controllers, sensors or pumps. It is also used in medical applications for monitoring and control systems when a galvanic insulation is required due to medical safety regulations. It is also suitable as an isolating interface in industrial, automotive, automation, security, consumer, telecommunications and computer applications.

Working Principle

The PS2911-1-V-F3-L-AX optoisolator principle of operation is based on the use of light waves coupled the two parts of the isolated system. It consists of a compact component assembly consisting of an infrared emitting diode, and a phototransistor placed face to face in a single package. The output of the device is a transistor inverter stage that switches on and off the output signal. The optical coupler uses the photo emitter and the phototransistor to transmit data from one side to the other side via light.

When an input signal is applied, the infrared light emitted by the photo emitter diode is received by the phototransistor provides amplified output, and the output of the opto-isolator is switched from a low state to a high state. When the signal is removed, the output voltage of the opto-isolator returns to its original low state. The output signal is in opposite to the input signal, and the opto-isolator can also be used as an inverter. The optoisolator also has a reverse leakage protection which prevents any reverse currents from flowing across the output.

Conclusion

The PS2911-1-V-F3-L-AX optoisolator is a highly efficient and reliable device that provides a high level of galvanic isolation and low power consumption. This device is designed for wide applications, such as medical, industrial and automotive applications, making it an optimal choice for interfacing sensitive control circuitry with the main logic or control system. With its low power requirements, low noise, and high efficiency, this optoisolator is a great choice for applications that require low compatibility, low power, high efficiency, and electrical isolation.
