MBR50045CTR – Diodes – Rectifiers – Arrays

The MBR50045CTR is a high power Schotky rectifier package. It is used in various applications. This article will discuss the application fields, construction, and working principle of this product.

Introduction

The MBR50045CTR is a high power Schotky rectifier package. It is capable of handling up to 45A at 45V for single or double sided boards, and up to 30A for four or more sided boards. It comes in a variety of packages, such as SMA, SMB, SMC, SMD, and SME. They are available in both surface mount and through-hole versions, and the construction of the package is optimized for maximum power dissipation and heat dissipation.

Application Fields

The MBR50045CTR is primarily used in a wide range of power management applications. It is used in DC-DC converters, power supplies, reverse battery protection circuits, and other applications where high power levels are required. It is also suitable for rectifying higher than 200KHz frequencies, while maintaining high efficiency.The device is also suitable for high temperature applications and can operate up to 150°C due to its high ruggedness and low voltage drop across the diode junction. It is often used in automotive, solar, and wind energy applications due to its ability to handle extreme temperature and vibration levels.

Construction

The MBR50045CTR is a Schotky diode array which consists of four diode pairs in an isolated package. The diodes are connected in parallel, and each pair forms a bridge rectifier. The metal case acts as a heat sink, and the device is epoxy molded for isolating and protecting the silicon chips. The backside of the device is shielded by a soldermask.

Working Principle

The MBR50045CTR functions as a rectifier, which is used to convert AC into DC, by allowing current to flow in one direction only. It consists of four pairs of diodes which act as a bridge rectifier, allowing current to move in either direction. Each of the pairs of diodes is connected in series and when an AC voltage is applied to the leads of the diodes, the current will flow through one of the bridge\'s diodes while the opposite diode is reversed biased.Each rectifier pair forms a diode bridge which rectifies the AC voltage. Each diode rectifies half of the waveform, which results in a DC output. The Schottky diodes in the MBR50045CTR also have a lower forward voltage drop, which results in higher efficiency.

Conclusion

The MBR50045CTR is a high power Schotky rectifier package which is used in a variety of power management applications. It is suitable for rectifying higher than 200KHz frequencies and can operate in extreme temperature and vibration levels. The device consists of four diode pairs which are connected in parallel and form a bridge rectifier, allowing current to move in either direction. The device also has a low voltage drop across the diode junction, which results in higher efficiency.
