Working Principle

The PS2861B-1Y-F3-L-A consists of an infrared LED, an output phototransistor, and a radiation shield. The LED will emit a light beam when a voltage is applied to the input pins, which is then picked up by the phototransistor and converted into an electric current. The output phototransistor pulls the output voltage low or high, depending on the state of the input. This process ensures that the input and output remain completely isolated from each other. The PS2861B-1Y-F3-L-A is a high-voltage device and can withstand a maximum operating distance of 5mm. It has a low operating current of 1mA and a low output collector-emitter voltage of 11V. The device also has an isolation resistance of between 1 x 10^8 - 2 x 10^8 Ω. The maximum collector current is 10mA, and the maximum output current is 0.25mA.

Conclusion

The PS2861B-1Y-F3-L-A is an optoisolator belonging to the Transistor, Photovoltaic Output category. It has multiple applications in power supply isolation, ranging from motor control circuits and appliance control to digital signal lines. It is a high-voltage device capable of withstanding up to 5mm of distance, and has a low operating current and output collector-emitter voltage. The device also has an isolation resistance of between 1 x 10^8 - 2 x 10^8 Ω.
