Optoisolators are a type of electrical component which uses a light-emitting diode (LED) to optically isolate a signal from an input circuit to an output circuit. The PS9817A-2-F3-AX optoisolator from CEL is one such component and is designed for use in logic output applications.

The PS9817A-2-F3-AX is an NPN Phototransistor Optocoupler with a 5V input voltage and a 4N31 Transistor output. It is a 4-pin device, with the pins arranged as: 1 ground, 2 Collector, 3 Emitter, and 4 Anode/Cathode. The device has a maximum collector current rating of 100mA, a maximum collector-emitter voltage rating of 60V, and an insulation resistance rating of 1000MΩ (Min). Additionally, it is RoHS Compliant and UL Recognized.

When integrated into an application, the function of the optoisolator is to electrically isolate the input signal from the output circuit. The optoisolator works by using an LED to produce light when an input signal is applied to it. This light activates a phototransistor in the optoisolator, which then produces an output signal. This output signal is isolated from the input signal, thus protecting the circuit from electrical noise and potential damage.

The PS9817A-2-F3-AX has several key features which make it well suited for logic output applications. Firstly, it has a low turn-on time, typically 5μs, making it better able to handle fast switching signals or protocols. Secondly, it has a high collector-emitter voltage rating of 60V, ensuring that it can handle high voltage signals. Thirdly, it has a guaranteed minimum insulation resistance of 1000MΩ, meaning that it can isolate signals while preventing noise from passing through the optoisolator.

The PS9817A-2-F3-AX optoisolator is designed specifically for use in logic output applications. Its features and specifications make it one of the most reliable and efficient optoisolators available, allowing it to reliably and accurately transfer signals between circuits while providing electrical isolation. It is a great choice for applications requiring isolation of fast-switching signals or for high-voltage applications.
