The 6N139#020 optoisolator offers a wide input voltage range that makes it suitable for many types of applications. Its high common-mode noise immunity and low on-state resistance offer improved noise immunity and reduced power consumption. The 6N139#020 has a wide operating temperature range which makes it perfect for those applications requiring consistent performance in different temperature ranges.

Working Principle

The 6N139#020 optoisolator is a transistor photovoltaic output type, which means it converts an electrical signal into an optical one for isolation purposes. It relies on a photon emitted from the emitter, which is then received by the collector. The collector is then used to generate a voltage and current. This current is then used to control an external switch, allowing it to be triggered by an electrical signal. The result is a reliable and efficient optical connection between two separate circuits.

The 6N139#020 optoisolator is comprised of a transmitter and two receivers. The transmitter is a small LED, which emits a photon when a voltage is applied across it. The two receivers, on the other hand, are small phototransistors, which detect this photon and convert it into a voltage. This voltage is then used to control the external switch.

The 6N139#020 optoisolator is designed to provide a very high level of isolation between two circuits, allowing them to operate without any interference even when a large voltage difference exists. This makes it an ideal choice for many applications that require reliable and efficient isolation.
