MBR1240MFST3G

Rectifiers - Single

The MBR1240MFST3G is a rectifier switching diode, intended for use in switching power supplies, inverters and as free wheeling diodes as well as for general purpose applications. It is designed to operate with a maximum peak repetitive reverse voltage of 1240V. It has a maximum forward continuous current of 40A and a maximum forward surge current rating of 290A. It also has a low forward voltage drop of 0.51V at 25A.

Application Field

The MBR1240MFST3G is suitable for use in a variety of applications. Due to its fast switching speed and low on-state voltage, the diode is ideal for use in low voltage, high frequency power supplies and inverters. It can also be used as a free wheeling diode in a variety of circuits, is suitable for avalanche and commutation, and can be used in a number of other general purpose applications.

Working Principle

The MBR1240MFST3G operates on a principle, known as rectification. When operating in a rectification circuit, the diode allows the current to flow in one direction, and blocks it in the other direction. This process is known as unidirectional current flow. The diode also has a low forward voltage drop, allowing greater efficiency in the circuit.

The MBR1240MFST3G also has a fast switching speed. This allows the current to be rapidly cut off when the voltage reaches a certain level. This is useful in applications such as inverters and switching power supplies. In these applications, being able to switch the current on and off quickly can prevent damage to the circuit.
