[[Introduction]]RB481Y-90T2R is a diode array, a type of electronic component used for rectification. It is usually a cluster of two or more diodes in one package and is used to change an alternating current (AC) into a direct current (DC). It is a critical component in the design of a wide range of electronics.[[Application Fields]]RB481Y-90T2R can be found in a variety of applications in the electronics industry, such as in inverters, drives, and UPS systems, as well as in power supply circuits. It is used in a range of industrial and consumer applications, including in security alarms, lighting fixtures, and telecommunications equipment.The diode array is also used in medical and analytical instrumentation, such as medical imaging and spectroscopy. It can be used to convert AC to DC in photovoltaic power systems, and also as a surge suppressor, as it provides a low forward voltage drop and can protect devices and circuits from short circuit events.[[Working Principle]]RB481Y-90T2R is an array of two or more individual diodes. It is typically constructed from multiple diode chips, such as two discrete conduction type diodes, connected in a common light-emitting diode (LED). When the diode array is connected to an AC voltage source, the diode will conduct current during the positive half cycle of the AC waveform and prevent current flow during the negative half cycle. By this process, the alternating current is rectified and becomes direct current.The working principle of the RB481Y-90T2R and most other diode arrays is based on the same principle: The diodes create a rectifying bridge, where one end of the bridge rectifies the AC voltage while the other end of the bridge blocks it. All the diode elements in the bridge start to conduct current when the voltage in the diode exceeds the forward voltage of the diode. This makes the diode array a good choice for applications where it is required to convert AC to DC. [[Conclusion]]RB481Y-90T2R is a diode array suitable for a range of applications. It works by converting the AC voltage in the circuit into DC and can be used for rectification, protection from short circuit events and in photovoltaic power systems. The array consists of two or more individual diodes and works by creating a rectifying bridge which allows current flow in one direction during the positive half cycle of the AC waveform, while blocking it in the negative half cycle.
