Optoisolators provide electrical isolation between input and output circuits and protect system components from hazardous or potentially hazardous levels of voltage, current, and power. The 4N28S(TB) optoisolator is a type of opto-isolator that uses a phototransistor as its output device. The main advantage of 4N28S(TB) optoisolators is their high speed switching and rugged construction.The 4N28S(TB) optoisolator is an electromechanical device that uses a light-emitting diode (LED) to emit light, which is then detected by a phototransistor. The LED and phototransistor are usually mounted on opposite sides of the same circuit board, so the light generated by the LED passes through a transparent window or a light guide before it reaches the phototransistor.The 4N28S(TB) optoisolator is a so-called transistor-output opto isolator, meaning that its output is a phototransistor instead of a photodiode. This type of optoisolator is highly reliable, as it is immune to impedance mismatches and does not suffer from electrostatic discharge or RF interference.The working principle of a 4N28S(TB) optoisolator is quite simple. When the LED is energized, it emits light that is picked up by the phototransistor. This causes the phototransistor to conduct current, which in turn causes the output to reach the desired logic level. If the LED is not energized, the phototransistor will not conduct current and the output will remain at the same logic level as the input.The main application field of 4N28S(TB) optoisolators is to provide isolation between high-voltage signals that may cause destructive voltage or current levels. These optoisolators are also used to extend the range of data signals and reduce the number of connections between two systems.The 4N28S(TB) optoisolator is designed to meet all basic application requirements. It offers high-density mounting, high-speed switching, and high-reliability performance. It is also economical and requires very little power to operate.In summary, the 4N28S(TB) optoisolator is a rugged, electromechanical device that uses a light-emitting diode (LED) and a phototransistor to provide electrical isolation between input and output circuits. This type of optoisolator is highly reliable and is mainly used to protect system components from hazardous levels of voltage, current, and power.
