RBR3MM40ATR

RBR3MM40ATR is a single diode rectifier, it is widely used in DC power supply, often the positive and negative side of the power supply, can prevent the electrical appliances between the positive and negative power supply and interchange, or in order to prevent the transient surge current, protection circuit circuit burn out. It also can be used in the switching power supply, commercial energy consumption, industrial energy consumption, switching machine and other occasions.

RBR3MM40ATR is one of the common type of rectifier diode, with package outline dimension 7.9mm*7.5mm, it is featured by low power, high reliability and excellent performance. The typical applications of RBR3MM40ATR are, AC adapters and Lighting, Uninterruptible Power Supply, Motor Controllers, Power Supplies, LED lighting, etc. The reverse current of RBR3MM40ATR is 40A, at the same time, its forward voltage is 1V, and it has a reverse breakdown voltage of 600V.

The working principle of RBR3MM40ATR is similar to most other rectifier diodes, which uses a p-n junction formed by a single piece of doped silicon semiconductor. When the forward current passes through the diode, the electrons of the n-junction are accelerated by the electric field, combined with the p-junction, and the holes of the p-junction are crossed in a plane. Then, these two pn junctions can flow a forward current, while the reverse bias voltage is cut off to stop the current flow, forming the basic characteristics of a rectifier. In addition, the design usually provide stronger anti-surge ability and higher temperature resistance by adding multiple dies in the diode package.

RBR3MM40ATR is a standard single diode rectifier, it is perfectly suitable for DC power supply, due to its high reliability and excellent performance, it can be used in many kinds of applications, making it a popular rectifier choice for designers. As a common rectifier type, it effectively prevents the reverse current and surge protection, making it ideal for any power supply application.
