PS2501-2

Optoisolators are electrical components used to isolate inputs from outputs, typically by providing a non-electrical way for signals to be passed between them. The optoisolator PS2501-2 is a transistor, photovoltaic output type, meaning that it uses light to detect differences in electrical signals between supply and load and then uses this data to control the transistor’s output. This component is mainly used in applications that require electrical isolation to prevent damage from leakage currents, excessive voltages, and electrostatic discharge.

Application field

The PS2501-2 is most often used in industrial applications, such as printed circuit boards, railway signaling, medical equipment, signal transmission, LED lighting, remote sensing, consumer electronics, and security systems. It is also suitable for more specialized purposes, such as for aerospace and military electronics, as well as communications systems, power supplies, and more.

Working principle

The optoisolator PS2501-2 works using a phototransistor output. When current is applied to the component, a small LED light on the input side is activated. This LED shines light onto the transistor on the output side, triggering the transistor to open and close in order to control the current. By doing so, it provides electrical isolation between the two sides of the device and prevents any electrical leakage.

The PS2501-2 optoisolator has a high isolation voltage of up to 2,000 V, which is beneficial for industrial applications. It also has a low on-state resistance of less than 10 ohms and a low off-state leakage of less than 100 nanoamps, which makes it ideal for applications where power consumption needs to be kept to a minimum. Furthermore, thanks to its small size, it is easy to incorporate into any design.

Conclusion

The optoisolator PS2501-2 is a specialized component used to provide electrical isolation between two parts of a circuit. It uses a phototransistor output to detect differences in electrical signals and converts this data into changes in the transistor’s output. This device is suitable for a wide range of industrial applications and is especially useful due to its high isolation voltage and low power consumption.
