Optoisolators - Transistor, Photovoltaic Output

The PS2561L-2-A is an optosolver with photovoltaic output, or an optoesolator, that provides photoelectric isolation between input and output. This optoelectronic isolation helps protect sensitive circuits from destructive high voltages and provides electrical isolation for data control lines.

The PS2561L-2-A consists of an infrared Light Emitting Diode (LED) and a photovoltaic cell in a single 4 pin single in-line plastic package. The LED is optically coupled to a silicon photovoltaic cell which has been designed to switch off a Darlington pair. When light is incident upon the photovoltaic cell, its output voltage raises from zero to its peak value which is in the range of 0.6V to 0.8V. A typical operating current of 10mA is required to turn the photovoltaic cell on.

The PS2561L-2-A optosolver is well suited for applications such as electronic timing and digital logic. It can be used to perform a number of tasks such as logic signaling, pulse transformers, switching, isolators, bell ringing, pulse transformers, display drivers, and more. The PS2561L-2-A supports both AC and DC input signal and has a maximum operating voltage of 32V. The package size is only 0.63-inch square and it is designed to resist ambient temperatures up to 85°C.

The PS2561L-2-A works by using a light emitting diode (LED) to optically couple its driving signal to the photovoltaic cell, which then generates voltage to turn the Darlington pair off. The maximum current that can be generated by the PS2561L-2-A is 1.6A, and its maximum voltage is 32V. The LED in the package has a rough viewing angle of 80°, which helps with its signal transmission. The PS2561L-2-A is also UL1577 approved, providing reliable operation.

The PS2561L-2-A optosolver is an excellent choice for applications requiring efficient and reliable data interface and photoelectric isolation. Its small size and low operating current make it ideal for embedded systems and industrial applications. Its wide operating voltage and wide viewing angle make the PS2561L-2-A a great choice for applications where several layers of protection are required, such as in the medical industry.
