6N135SD

Optoisolators are popular electrical components that are used to provide an electrical isolation barrier between two circuits. These devices use a physical barrier to prevent current from flowing between the two circuits while allowing signals to pass, allowing a signal to be transmitted across circuits without having an influence on each other. The 6N135SD is an optoisolator that is specifically designed to have a transistor-coupled photo voltaic output. This optoisolator allows for ultra-high speed photocoupler applications up to 500 Kbps, as well as offers high common mode transient immunity.

Application Field

The 6N135SD optoisolator is designed to suit a wide variety of circuits for a number of applications. It can be used in power supplies, home appliances, and automated machinery, and is most commonly used in communication equipment. It prevents signals from passing between circuits and corrupting each other, providing an electrical isolation layer.

Working Principle

The optoisolator consists of two main parts – the input and the output. The input is typically an LED that emits a light that is of a wavelength visible to the human eye. The output consists of a transistor switch, which when triggered by the LED, forms a closed circuit. When the input is activated, it emits a light that is received by the transistor switch, which then triggers the output current.

The 6N135SD optoisolator is different from standard optoisolators in that it has a transistor-coupled photo voltaic output. This means that the transistor is directly connected to the output terminal, eliminating the need for additional components. This also provides a higher level of speed, allowing for ultra-high speed photocoupler applications up to 500 Kbps.

The 6N135SD is also designed with a high common mode transient immunity, meaning it is more resistant to the interference caused by alternating currents and noise on the power line. This immunity is achieved through the use of improved filter technology, which is designed to remove noise and give the optoisolator a higher level of accuracy in detecting signals.

Conclusion

The 6N135SD optoisolator is an effective and reliable device for providing electrical isolation between two circuits. It features a unique transistor-coupled photo voltaic output, allowing for ultra-high speed photocoupler applications up to 500 Kbps, as well as a high common mode transient immunity. It can be used in a wide variety of applications, and is most commonly used in communication equipment.
