Optoisolators, also known as optocouplers, are optoelectronic devices used to isolate two electrically separate circuits. They provide galvanic isolation between input and output to eliminate the risk of electrical shocks and ground loops. The most common optoisolators use a light emitting diode (LED) and a phototransistor to transfer information between the two circuits. Examples of these devices are the Optotraxx PC367N, also known as a transistor, photovoltaic output optoisolator.

The PC367N is an optoisolator whose main purpose is to provide galvanic isolation between two circuits. It is composed of a light emitting diode (LED) that is driven by either DC or AC voltage and a phototransistor that amplifies the current. The LED is isolated from the phototransistor by an optically transparent micro barrier. The barrier prevents electrical conduction between the LED and the phototransistor while allowing the light to pass through and activate the phototransistor.

The main application field of the PC367N optoisolator is in the control of high voltage and current circuits. This optocoupler is capable of providing galvanic isolation of up to 3000 Volts RMS, and can control circuits of up to 2.5 Amperes at 120 Volts RMS. These optoisolators are frequently used in embedded systems, electric motors, power supplies, power amplifiers, communication circuits and other electrical applications that require control of high voltages or currents. Other applications include operation of AC and DC motor starters, relays, solenoids, thyristors and IGBTs, and other control devices.

The PC367N is also a voltage-input optoisolator; meaning that the LED is driven by a voltage input source. This voltage input is usually provided by a digital signal from a microcontroller and transmitted to the optoisolator via a cable or other transmission method. The LED that forms the intensifying element transforms the electrical energy of the input voltage into light energy, and the phototransistor that serves as the receiving element, transforms the light energy back into electrical energy. The phototransistor is the source of the output current, which can be used to control a load.

The optoisolator provides a high degree of electrical isolation between the input and the output by transforming an input signal into an optical signal, and then transforming it back into an electrical output. This process of isolation prevents false triggers and protects circuits from static electricity, transients, and high frequency interference. Additionally, the optoisolator can protect the output circuit from connection problems that could cause a short-circuit or overload.

The PC367N optoisolator is a high performance, reliable, and cost-effective solution for isolating electrical signals in a wide range of applications. It is designed for both DC and AC inputs, and can provide up to 3000 Volts of RMS isolation, and can handle circuits of up to 2.5 Amperes. In addition, its low power consumption and fast response time make it an ideal optoisolator for many embedded applications.
