Optoisolators are optoelectronic devices used in circuits to electrically isolate the input or output from the rest of the circuit. In an optoisolator, an optical signal is used to transmit information between optical and electrical components, allowing the signal to be separated from the circuit and isolated from the high voltages present in the circuit. The optoisolator can be used as a way to switch a signal without the need for a high voltage, such as in a power supply, or even as a way to protect sensitive electronic components or circuits from high voltage fluctuations or electric noise. Transistor, photovoltaic output optoisolators such as the PS8302L2-V-AX are an example of optoisolators used for power supplies and industrial control applications.

The PS8302L2-V-AX is a photovoltaic output optoisolator in a four-pin package featuring a photovoltaic element and a current-switch transistor output for applications where relatively fast switching settings are required. It requires a low-voltage 1.2V power supply and exhibits excellent on-state speed characteristics with a maximum collector-emitter voltage of 50V. The optoisolator has a minimum on-state current of 3mA and a maximum off-state voltage of 1µA. Its minimum holding current is 3mA and its switching speed is 0.2µS.

This optoisolator is well suited for use in applications such as industrial control circuits, power supplies, electrical interference protection, and RF signal monitoring. In industrial control circuits, the optoisolator can be used for connecting and controlling devices such as motors, solenoids, and robotic arms. In power supplies, it can be used to regulate the electrical current flowing to and from a device, providing a faster and more efficient switchover of current as well as protection for sensitive digital circuits. It can also be used in conjunction with other optoisolators, such as those with an optically isolated input, to further isolate input and output signals from each other. It can be used in RF signal monitoring applications due to its fast switching and excellent on/off characteristics, providing accurate and reliable signal detection.

The PS8302L2-V-AX optoisolator works in the same manner as other transistor photovoltaic output optoisolators. It consists of a photovoltaic element, such as a light-emitting diode or LED, and a transistor switch. The LED generates light when an electric current passes through it, resulting in an electrical signal that is proportional to the current. This signal is then sent to the base of the transistor, which acts as a switch and allows the current to flow from the emitter to the collector, thus completing the circuit. The signal is then sent back to the LED, and the cycle begins again. This process allows the optoisolator to transfer the electrical signal, isolating it from the rest of the circuit.

The PS8302L2-V-AX optoisolator is a reliable and efficient way to electrically isolate signals and provide digital switchover protection and noise reduction in industrial control and power supply applications. It offers excellent on-state speed characteristics and a low-voltage power supply, making it ideal for use in a variety of electronic systems.
