MBR20100CT Diode: Principle, Circuit Diagram and Features

Post Date: 2024-07-10 , ON Semiconductor

MBR20100CT Description

The MBR20100CT is a Schottky rectifier diode commonly used in power supply applications due to its high efficiency and low forward voltage drop. It has a maximum repetitive peak reverse voltage of 100V and can handle an average rectified current of up to 20A. 

MBR20100CT Working Principle

The MBR20100CT operates based on the principles of a Schottky barrier diode, which utilizes a metal-semiconductor junction to achieve its rectifying behavior. When forward-biased, the diode allows current to flow with minimal voltage drop due to the low barrier potential between the metal and semiconductor, resulting in high efficiency and reduced power loss. In reverse bias, the diode blocks current flow up to its maximum rated reverse voltage. It efficiently converts alternating current (AC) to direct current (DC) with minimal energy dissipation.
