Optoisolators are devices that use light to electrically isolate two circuits and eliminate the possibility of circuit noise and ground loop issues. They also protect low voltage circuits from high voltage transients and surges, providing galvanic isolation. The IL358T is a type of optoisolator of the Transistor Photovoltaic Output variety. This article will discuss the application fields and the working principle of the IL358T optoisolator.

The IL358T optoisolator is a transistor, photovoltaic coupled optoisolator that is widely used in a variety of applications. It is an effective digital signal isolator and it features good performance characteristics, low power consumption, and a very small size. It can be used in applications who require high noise immunity and ground loop elimination, such as industrial automation, medical equipment, controllers for power electronics equipment, and factory automation. In addition, it can also be used in systems where noise, transients, and power surges need to be avoided.

The working principle of the IL358T optoisolator is based on the photovoltaic effect. This effect happens when photons from light are absorbed by a semiconductor, and this generates an electrical current. The two circuits of the optoisolator, the input and the output, are completely isolated from each other. The input of the optoisolator is illuminated by infrared light from a light-emitting diode (LED), and the output is connected to a transistor. The transistor is activated when the LED emits photons which are then absorbed by a photodetector in the output circuit, resulting in an electrical current.

The IL358T optoisolator is a very effective way to isolate two circuits, since the two circuits are physically separated from each other. This eliminates the possibility of circuit noise and ground loop issues. In addition, it provides galvanic isolation and protection from high voltage transients and surges. Furthermore, it has a very low power consumption and a very compact design which makes it suitable for a variety of applications.

In conclusion, the IL358T optoisolator is a transistor, photovoltaic output device that is widely used in a variety of applications. It is an effective digital signal isolator and it features good performance characteristics, low power consumption, and a very small size. Its working principle is based on the photovoltaic effect, and it is a great way to eliminate the possibility of circuit noise and ground loop issues, as well as providing protection from high voltage transients and surges. Therefore, the IL358T optoisolator is an ideal choice for applications who require circuit isolation.
