Optoisolators are devices that transfer electrical signals between two isolated circuits. These devices are constructed with an emitter circuit, which is usually an infrared LED, and a detector circuit, which is typically a photodiode or a phototransistor. The 6N138SM is one type of optoisolator. It functions as an optoisolator by transmitting digital signals between two circuits, isolating them and preventing them from affecting each other. This is accomplished by a light-sensitive phototransistor that detects the light from the infrared LED and converts it into an electrical signal. When the light is not blocked, the phototransistor stays in an “off” state and the electrical signal is not transmitted. However, when the light is blocked, the phototransistor is activated and the electrical signal is transmitted.

The 6N138SM optoisolator is a type of transistor output optoisolator that has a photodiode connected in series with a phototransistor. The photodiode acts as the emitter circuit while the phototransistor acts as the detector. Since it is a transistor output, the 6N138SM has an internal current gain. This means that when the LED is off, the optoisolator will amplify the current, resulting in a stronger signal. This makes the 6N138SM ideal for applications that require high levels of isolation. The 6N138SM optoisolator is also a photovoltaic output, meaning that it can convert the optical signal from the LED into electrical energy.

The 6N138SM optoisolator is suitable for use in a variety of applications, such as driving logic gates, controlling motors, switches, relays, digital communications, and signal isolators. It can also be used in a variety of industrial and automotive applications. The 6N138SM is designed to withstand harsh environments, such as high temperatures, humidity, vibration, and pressure, making it ideal for use in harsh environments. Additionally, the 6N138SM optoisolator has an excellent isolation rating, making it suitable for applications requiring high levels of electrical isolation.

In summary, the 6N138SM is a transistor output, photovoltaic output optoisolator ideal for use in a variety of applications, such as signal isolation, digital communications, and driving logic gates. It is capable of withstanding harsh environments and has an excellent isolation rating, which makes it suitable for applications requiring high levels of electrical isolation. The 6N138SM optoisolator is thus an ideal solution for applications requiring high levels of isolation.
