Optoisolators are electric components used to isolate electrical signals from external electrical sources. This is done by converting the external signals into a voltage or current output, which are isolated from the primary signals. VOL628A-3T is a type of opto-isolator which is classified as a Transistor, Photovoltaic Output device.

This particular opto-isolator is designed for a wide range of applications. It can be used in digital, analog and timing circuits. Its output is a transistor-based photovoltaic output with a high level of electrical noise immunity. It has a rated collector current of up to 1A and can operate up to a temperature range of -30°C to 110°C.

The VOL628A-3T has a working principle which is based on the photovoltaic effect. When light passes through the device, it causes the electrons of the light-sensitive material to be displaced in the opposite direction. This, in turn, creates a voltage difference (aka a voltage output) between the material and its surrounding environment. This output can then be used for a variety of applications, such as driving relays and switching logic circuits.

The device itself is composed of several components. These include a reflective layer which redirects the light back onto the light-sensitive material, an optical filter which filters out certain wavelengths of light, and a photodiode which converts the light into electrical energy. In addition, the photovoltaic cell is also surrounded by reflective materials which helps decrease the chances of light interference within the device.

The VOL628A-3T is also equipped with several safety features. These include a dielectric isolation of up to 4500VAC (50/60Hz) which helps protect the device from electrical shocks and surges, and a lightning protection circuit which guards against damage caused by lightning strikes.

The VOL628A-3T is a versatile and reliable opto-isolator, designed for a vast range of applications. Its photovoltaic output is ideal for controlling relays and switching logic circuits. Its high level of immunity to electrical noise allows it to be used in harsh environments, such as industrial settings. Furthermore, its safety features make it suitable for protecting sensitive components from electrical shocks and surges.
