The MBRB20H45CT-E3/81 is a bridge rectifier array component made by ON Semiconductor, featuring 20A of forward current, 800V of peak repetitive reverse voltage, and 200°C/W of thermal resistance. It is a two-phase component, meaning it has two rectifier bridges connected in parallel. It has extremely fast recovery times, meaning the component becomes non-conductive quickly, resulting in low emissions levels.

The MBRB20H45CT-E3/81 belongs to a group of components known as rectifier arrays. Rectifier array components are composed of individual rectifier bridges, usually connected in parallel, and are designed for robust, high-current applications. They are used in power supplies, lighting, and motor speed control, among other applications. They can be used in AC to DC or DC to DC circuits, often providing the primary bridge rectification for the power supply.

The MBRB20H45CT-E3/81 has a variety of features that make it suitable for many applications. It is compliant with International Standard IEC 60320-1, making it a worldwide safety standard for DC applications. It also has thermal shutdown, which activates at 125°C and turns off the component after a short time to avoid overheating. It also has an overvoltage circuit which limits the reverse voltage input, protecting the component against damaging overvoltage conditions.

The working principle of the MBRB20H45CT-E3/81 is relatively simple. In its most basic form, it acts as a bridge rectifier, meaning it takes alternating current (AC) and converts it into direct current (DC). The construction of the component consists of two rectifying diodes, which are connected in a bridge circuit configuration. As the AC power passes through the two rectifying diodes, one allows current to flow freely while the other blocks it. This creates a DC signal, which can then be sent to a capacitor, filter, or other component to provide the desired output.

The MBRB20H45CT-E3/81 applications span across a variety of fields and industries. It can be used as a bridge rectifier in DC power supplies, linear adapters, and uninterruptible power supplies. It is also often used in solar power projects, as its two phase design is well-suited for solar inverter applications. In lighting applications, it is commonly used in LED strips, due to its high current capacity and low thermal resistance.

The MBRB20H45CT-E3/81 is an excellent choice for a variety of applications due to its robust design features, high current specifications, and high reliability. Its working principle is fairly simple, thus making it a great choice for engineers and DIY hobbyists alike. With its wide array of applications and its relatively low cost, it is one of the most popular rectifier array components on the market.
