Optoisolators are electrical components that use light signals, rather than electrical signals, to isolate two circuits. This type of isolation, called photo-coupling, is critical in a variety of applications in which one circuit must be kept independent from the other. The PS2801-1-K-A is a type of optoisolator that utilizes transistor photovoltaic output.

The PS2801-1-K-A consists of an LED optically coupled to an integrated photovoltaic/transistor circuit. The LED is positioned close to, but not in direct electrical connection with, the photovoltaic/transistor circuit, allowing the two circuits to be completely isolated and preventing the transfer of electrical energy or signals from one circuit to the other. As the LED is illuminated, photons are created which are then absorbed by the photovoltaic/transistor circuit, creating a voltage which can be used to trigger the transistor.

The PS2801-1-K-A is specifically designed for high-speed switching applications with a maximum forward current of 1.8 mA and isolation voltage of 5300 VRMS. These specifications allow for the PS2801-1-K-A to be used in a variety of applications, such as input/output interfaces, trigger circuits, and signal level control. It is often used in applications where electrostatic interference, voltage transients, and electrical noise must be kept to a minimum. The PS2801-1-K-A is also capable of operation at temperatures between -40°C and 85°C, allowing for use in a wide range of environments.

The PS2801-1-K-A is an ideal optoisolator for applications requiring the complete electrical isolation of two circuits. The integrated photovoltaic/transistor circuit is triggered when the LED is illuminated, which allows for the reliable transfer of information and controls between the two circuits with no electrical interference.
