MA3D749A Diodes - Rectifiers - Arrays application field and working principle

The MA3D749A diode-rectifier-array family is a power-dense series of devices designed for use in rugged, low-voltage applications. This series combines the power efficiency of advanced diode-array designs with the reliability of conventional MOSFET devices. The MA3D749A series thus offers a cost-effective, power-efficient solution for a wide range of applications, from automotive and industrial control systems to multiple-input DC/DC converters and isolated DC/AC power supplies.The MA3D749A series features a low-profile, single-pole package with an easy-to-use, pin-compatible pin-out design. For the same switching frequency, each device offers a low turn-on voltage drop to increase the efficiency of the diode array by reducing power losses. These devices also feature an ultra-low reverse recovery time, for minimising standing power losses. The robust silicon construction and reliable contact design ensure the highest reliability, even in the harshest environmental conditions.The MA3D749A series is an ideal choice for low-voltage DC/DC and DC/AC power conversion applications. It is also suitable for use in automotive/industrial control systems and in multiple-input DC/DC converters. These devices are available in a variety of configurations with currents ranging from 4A to 180A.When used in a diode-array configuration, the MA3D749A series increases power efficiency while reducing losses due to its low turn-on voltage drop and ultra-low reverse recovery time. The single-pole package and pin-compatible pin-out design further decrease time-to-market by simplifying the circuit design process and reducing assembly costs. The robust construction of these devices provides superior reliability and increased lifetimes due to their ESD immunity and excellent thermal cycling performance.The MA3D749A diode-rectifier-array family combines power efficiency, reliability and a cost-effective, easy-to-use pin-out design to provide an ideal solution for a wide range of applications. Its low turn-on voltage drop and ultra-low reverse recovery time reduce power losses, while its robust construction increases reliability, making it suitable for use in the harshest environmental conditions. These features, combined with its wide variety of current ratings, make the MA3D749A an ideal choice for automotive/industrial control systems, multiple-input DC/DC converters and isolated DC/AC power supplies.
