Diodes - Rectifiers - Arrays are the principal components of any power electronic circuit because they bookend the power stage by providing enabling the circuit to block unwanted current from passing through the circuit and also conducting a flow of current from one component to the other. The BAT54CDW-7-F, a component of the Diodes - Rectifiers - Arrays category, is a double Schottky Barrier Rectifier Array, a component for performing reversible rectification current in a semiconductor device.

The BAT54CDW-7-F Rectifier Array is designed for low forward voltage drop and high reverse leakage current that is typically used for high-efficiency, low voltage, switch-mode power supplies with a variety of input voltages. The component is mounted on a leadframe taping and it has no pins, so it is suitable for slim-profile, low-voltage and low-current applications, making it ideal for usage in modern Smartphone, computer and micro-processors.

The BAT54CDW-7-F works under the principles of both Schottky Barrier Rectification and tunneling. In Schottky Barrier Rectification, a rectifying “barrier” voltage forms a lower resistance current path that serves to conduct current in the forward direction, then it serves to block the conduction of current in the reverse direction. This service allows for the quick switching of current paths, thus transferring power from one component to the other. In tunneling, for conduction to occur, electrons and holes must tunnel “through” the barrier and thus making up the Schottky junction.

In practical application, the BAT54CDW-7-F Rectifier Array is most useful in power supplies, non-isolated DC/DC converters, Compact switching cubes, or in any application needing a linear regulator or capacitor less rectifier. It is also used in medical equipment and consumer products, especially where size and cost are major considerations. The desired product characteristics are the low forward voltage drop and high reverse leakage current, which create better power efficiency and less power loss.

The BAT54CDW-7-F is an effective double Schottky Barrier Rectifier Array and is an excellent choice for reducing power losses in a variety of commercial or consumer applications where interior space is limited due to its small size. It operates under the principles of Schottky Barrier Rectification and tunneling, making it an ideal component for reversible rectification in the power stage of low voltage, low current designs, and for those seeking high-efficiency and low forward voltage drop.
