FMB-24M

FMB-24M diodes are one of the most commonly used subminiature rectifier packages in the field of rectifiers. This package is available in both unidirectional and bidirectional types, and includes an array of Schottky barrier diodes in a common cathode configuration. This makes it suitable for applications that require a large amount of current and power in a package with a small footprint.

The FMB-24M diode package is designed for a variety of applications. It is commonly used in AB-regulation circuits, solar cell applications, switch-mode power supplies and DC/DC converters. It can also be used as a fast switching logic device in communication systems. Furthermore, the FMB-24M is able to provide high isolation for flyback and forward converters.

In terms of working principles, FMB-24M diodes are based on the concept of Schottky barrier diodes. These diodes have a low voltage drop across them when reverse-biased, which makes them suitable for use in high-frequency switching applications. When the diode is forward-biased, the Schottky barrier height and surface defects combine together to form a narrow depletion zone, which reduces the voltage drop to a fraction of the reverse-bias voltage. This low voltage drop increases the efficiency and reduces losses.

In addition to the Schottky barrier diodes, FMB-24M diodes use a common-cathode configuration in order to create a low impedance connection between multiple diodes. This further enhances the efficiency of the rectifier device by providing a higher current rating and voltage rating compared to a single diode device. The common-cathode feature also helps with thermal management, as the current is shared between several diodes.

The FMB-24M diode array is also well-suited for circuit protection applications due to its low thermal resistance. The wide range of working voltages, power ratings, and reverse voltage ratings allow it to be used in a wide variety of conditions. Furthermore, its high peak current capacity means that it can handle heavy loads without any degradation in performance. In summary, the FMB-24M diode array is an ideal solution for applications that require low losses and efficient circuit protection.
