Working Principle

The 3N251-E4/72 bridge rectifier is designed to convert AC voltage into DC voltage. It is composed of four diodes arranged in a bridge configuration. When an AC voltage is applied to the bridge rectifier, the diodes act as one-way valves, allowing current to flow in one direction only. This creates a DC output voltage by blocking the parts of the alternating current waveform that would otherwise cause the current to flow in the opposite direction.

The bridge rectifier also provides protection against over-voltage, as the diodes limit the maximum voltage that can be applied. This helps ensure that the device and connected components are not damaged by excessive voltage.

The 3N251-E4/72 bridge rectifier is an ideal choice for applications requiring high current and low voltage. Its efficient design and capability to handle input voltages as low as 1 V make it suitable for a variety of applications, including DC power supplies, variable speed motors, battery chargers, and lighting.
