Diodes - Zener - Arrays: PZU14DB2, 115 Application Field and Working Principle

Diodes - Zener - Arrays, including the PZU14DB2, 115, are specialized semiconductor components that provide an array of electrical functions such as signal conversion, switching, regulation, and isolation. The PZU14DB2, 115 in particular is a surface-mount device (SMD) package containing 9 individual diodes to form a bridge rectifier or a full-wave rectifier. It is one of the most commonly used rectifier devices for implementing DC voltage conversion in the industrial and electronic markets.

Bridge Rectifier and Full-Wave Rectifier

A bridge rectifier is an electrical building block made up of 4 or more diodes used to convert AC inputs to DC outputs. It acts as a one-way “valve”, allowing electrical current to flow in only one direction. In a full-wave rectifier, both half-cycles of the input voltage are converted to a uni-directional voltage and can be used to produce a pure direct current.

How Does it Work?

The PZU14DB2, 115 is arranged in a symmetrical bridge arrangement in order to provide a full-wave rectifier application. During the positive half-cycle of the input voltage, in which the positive side of the AC is at a higher potential than the negative side, the top two anodes of the diodes are forward biased and the bottom two anodes are reverse biased. The left three cathodes are connected to the negative side of the AC source, while the right three cathodes are connected to the positive side.When the negative half-cycle arrives, the top two anodes become reverse biased and the bottom two anodes become forward biased, while the left three cathodes are connected to the positive side of the AC source and the right three cathodes are connected to the negative side. In this way, current is able to flow through the circuit in only one direction, providing a DC output.

Applications

The PZU14DB2, 115 is most commonly used to create DC voltage from AC voltage inputs. It can also be used to take DC voltage from one part of a circuit and convert it to another DC voltage level. It is capable of handling moderate power and voltage for a variety of industrial and electronics applications, such as power supplies, solar panels, and motors, as well as consumer electronics, like electronic appliances and battery chargers.

Conclusion

The PZU14DB2, 115 is a specialized SMD package include 9 diodes that can be used as either a bridge rectifier or a full-wave rectifier. It is designed to convert AC voltage to DC voltage and can handle moderate power and voltage. It is used in applications such as power supplies, solar panels, and motors, as well as consumer electronics, like electronic appliances and battery chargers.
