Diodes - Rectifiers - Arrays: MBRTA80040 Application Field and Working PrincipleA rectifier is an electrical device that converts alternating current (AC) to direct current (DC). It is an indispensable part of a wide range of applications, from cell phones to electric cars. The MBRTA80040 is a rectifier array developed by a leading diode manufacturer and designed with high current and low voltage in mind.The MBRTA80040 low voltage rectifier array integrates eight high power Schottky rectifiers and is designed specifically for applications that require low forward voltage and high current carry capability. It is ideal for power, protection and general purpose rectification applications, and is suitable for a variety of applications such as controllable power, motor control, pulse-width modulation and soft-start circuits. The MBRTA80040 features a reverse voltage (VRRM) of 800V and a continuous forward current (IF(AV)) of 40A (80A non-repetitive peak). It has a low voltage drop of 0.6V at 25°C, enabling energy savings and a reduction in the total system cost. The device also features low thermal resistance, a maximum operating junction temperature of 150°C, and is UL approved.The MBRTA80040 rectifier array is easy to install and use. It has a convenient plug-in design and requires no external circuit components. Its extremely low voltage drop can reduce Vf by up to 70%, which improves system efficiency and is ideal for automotive, communications and computing applications. In terms of working principles, the rectifier array works by schottky diodes, which are of a special type of engine. Schottky diodes allow opposite current to pass through while blocking current in the same direction. When two opposing current sources are connected, a rectifier array is formed, with one diode per pair of pins. On the upper pin (the anode), when the voltage is below the breakdown voltage, the diode is blocked and no current passes. On the lower pin (the cathode), when it has a positive voltage, current flows freely; however, when the voltage is negative, the same diode is blocked. This allows a current to flow only in one direction and thus converts AC to DC. The break-down voltage of the diode is set to reduce average losses and to minimize heating of components, as well as preventing any damage due to overload. To ensure safety, the MBRTA80040 features an isolation voltage of 1550V and is constructed with junction area isolation, which prevents the leakage current from one pin to the other. It also features a built-in over-temperature protection which shuts down the device when the temperature exceeds its maximum rating.In conclusion, the MBRTA80040 low voltage rectifier array is an ideal solution for a variety of applications from power supply to motor control due to its low voltage drop and high current carrying capability. It is easy to install and use, has a low thermal resistance and offers excellent stability and reliability due to its built-in features of isolation and over-temperature protection.
