Optoisolators are electronic components that electrically isolate two circuits. They are available in different sizes and styles. At the heart of optoisolator components is an LED and a phototransistor, which are mounted facing one another on the same substrate.

The 6N137A logic output optoisolator component is a popular choice for many applications, from powering embedded devices to controlling lighting and security systems. This optoisolator is an 8-pin dual in-line package (DIP) component. It has been widely used in industrial and commercial applications for years.

The 6N137A optoisolator consists of a gallium arsenide (GaAs) light-emitting diode (LED) encapsulated in a plastic housing. The control electrode of the LED is coupled to an input signal. When the input voltage applied to the LED exceeds the LED’s threshold voltage, the LED emits light, which is then detected by a photodetector, such as a phototransistor. The phototransistor amplifies the optical signal generated by the LED and produces a corresponding output voltage.

The 6N137A optoisolator is designed to be used with a wide range of input voltages, from 5V to 18V. It has a working current of 10mA and a typical output voltage of 2.4V. It is designed to have a high input–output isolation and provides up to 2500V RMS of isolation. This means that it can protect circuits and equipment from high voltage transients and electrical surges by isolating the two circuits electrically.

The 6N137A optoisolator can be used in a variety of industrial and commercial applications to isolate sensitive circuits from external noise or to provide a high level of protection from electrical transients. It is often used in applications such as industrial automation, communications systems, meters, medical devices, embedded system designs, and more.

The 6N137A optoisolator is a reliable and durable component that can be used in many applications. It is fast, efficient, and has a long operational life. It is widely available and is offered in most major component manufacturers’ catalogs.

In summary, the 6N137A optoisolator from Fairchild Semiconductor is a reliable, efficient component used in a wide range of applications. It has a high input–output isolation rating of 2500V RMS, and is designed to work with a wide range of input voltages. This optoisolator is a great choice for industrial and commercial applications due to its durability, long-term reliability, and its ease of use.
