The MBR340G is a Schottky diode and rectifier manufactured by ON Semiconductor. This component has a maximum current rating of 3A and a maximum operating voltage of 40V. It is designed to optimize power dissipation, reduce losses, and provide a very low forward voltage drop. It enables fast switching with low power loss, making it an ideal choice for low voltage and high frequency applications. It is also highly efficient, with very low reverse leakage current. The MBR340G is available in a TO-220AB package and can be used in a variety of applications, such as power supply circuits, motor control circuits, and telecom and networking equipment.
