Diodes - Rectifiers - Arrays

A MBRF40035 is a rectifier diode array, which is a diode, composed of two or more devices connected in parallel. The most common type of rectifier diode array is the bridge configuration, where four tunnel diodes are connected in a square to form a bridge. The bridge rectifier diode can be used in a variety of different applications, such as in power conversion, rectification, and signal conversion.

Application field

The MBRF40035 rectifier diode is particularly well-suited for various applications due to its robustness, durability and low contact resistance. It is primarily used as a switch in AC and DC power systems, such as in AC/DC power supplies, solar energy conversion, automotive and industrial power systems, motor drives and rectifiers. It can also be used for noise suppression and over-voltage protection in telecommunications and electronics.

In addition, the MBRF40035 rectifier diode is used in a variety of other applications, such as in electric heating, automotive alternators, and motor control circuits. It is also often used for motor speed control, as it can provide noise and sudden motion protection, as well as for switch mode power supplies, as it increases switching speed and reduces the number of semiconductor devices necessary for such applications.

Working Principle

When an AC signal is applied across the MBRF40035 rectifier diode array, it works by separating the positive and negative semi-cycles of the signal. The positive semi-cycle is then redirected to one of the diode pair and the negative semi-cycle to the other, resulting in DC power. The four tunnel diodes in the bridge rectifier diode array act as a single diode, allowing positive voltage to pass through one direction and preventing it from passing in the other direction.

The four terminals of the MBRF40035 come in two pairs. The four terminals are labelled as A1, A2, B1, and B2; A1 and A2 being one pair, and B1 and B2 another. During the positive half-cycle of the applied AC voltage, the two pairs of terminals, A1/A2 and B1/B2 will have the same voltage value. During the negative half-cycle, the A1/A2 pair will have negative voltage value and the B1/B2 pair positive voltage value. This results in current flowing in only one direction, from A1 to A2 and from B1 to B2.

Conclusion

The MBRF40035 is a versatile and reliable rectifier diode array that has found widespread use in power applications. It is composed of four tunnel diodes arranged in a bridge configuration, which allows it to separate the positive and negative semi-cycles of the AC signal and effectively converts it to DC power. Its versatility makes it ideal for applications such as AC/DC power supplies, noise suppression, solar energy conversion, and motor drives.
