Optoisolators - Transistor, Photovoltaic Output

An optoisolator, also known as an optocoupler, opto-isolator, photocell isolator, photocoupler, or optical isolator, is an electronic component which provides a way of isolating an input from an output using an infrared light source (IR). In the HCPL-814-360E, the input is an electrical voltage sent to the optoisolator, while the output is a photovoltaic voltage released from the optoisolator. The optoisolator acts as a relay between these two sources, ensuring that neither the input or the output source is connected to the other. The HCPL-814-360E optoisolator is a solid-state integrated circuit which contains a high gain NPN silicon phototransistor and a photodiode LED. It has a typical on-state gain of 500, with a typical reverse current of 0.2μA, making it suitable for applications requiring high on-state gain and low reverse leakage current.The HCPL-814-360E can be used in a wide variety of applications, including current sensing, line regulation, power supply isolation, and level shifting. In addition, it can also be used as a voltage barrier in systems which require optical isolation. In these applications, the optoisolator acts as a isolator, separating the input signal from the output signal. This ensures that the output signal will remain unaffected by input noise and over-voltage, preventing potential failures from occurring.The working principle behind an optoisolator is simple. The input signal is sent to the LED within the HCPL-814-360E, which in turn operates as a light source. This light source is then detected by the integrated phototransistor, which then emits the photovoltaic voltage as the output signal. This output voltage is isolated from the input signal and is thus unaffected by noise and overvoltage, ensuring the reliability of the system.In conclusion, the HCPL-814-360E is a versatile optoisolator which can be used in a wide variety of applications, including current sensing, line regulation, power supply isolation, and level shifting. It provides a high on-state gain and low reverse leakage current, ensuring reliability and signal integrity. The simple working principle of the optoisolator ensures that the output is isolated from the input, ensuring that the output remains unaffected by noise and overvoltage.
