Diodes - Rectifiers - Arrays

The MBRTA50040R is a family of diodes and rectifiers array with 3-phase bridge rectifiers with built-in metal oxide and varistors (MOV). This product family of diodes are high power, fast and soft recovery rectifiers. It is ideal for use in a high power, high frequency switch-mode power supply (SMPS) applications.

Application Field

The MBRTA50040R is primarily used in three-phase applications, like uninterruptible power supplies (UPS), DC-DC converters, power supply systems in renewable energy off-grid, industrial and automotive applications. Its high frequency, low conduction loss, low reverse recovery characteristics make it an ideal choice for the higher frequency, high power applications. Furthermore, it is designed to handle the high reverse surge currents.

Working Principle

The MBRTA50040R works on the basic principle of rectification. In rectifiers, the alternating current (AC) is converted into direct current (DC). This is accomplished by the switch-mode power supply (SMPS). It works by switching the input voltage with a transistor, turning it on and off at an appropriate rate to generate a specific frequency, usually greater than 20 KHz, before sending the voltage to the rectifier. The three-phase design of MBRTA50040R rectifier provides an efficient AC-to-DC conversion and helps to minimize power dissipation. It features a built-in metal oxide varistor (MOV), which is designed to provide enhanced transient protection, and to reduce the energy dissipation in the reverse recovery phase, prolonging the product operating lifetime.

The MBRTA50040R family of diodes and rectifiers array is a great choice for efficient and reliable AC-to-DC conversion. Its compact dimensions, fast and soft recovery characteristics, high frequency operation, and low conduction and reverse recovery losses make it ideal for use in a wide range of applications.
