BAT46W-HE3-08

Diodes - Rectifiers - Single

A single diode rectifier is an electrical device that utilizes a one-way electrical flow of current electronically. The most common device for single diode rectification is the BAT46W-HE3-08.

Application Field

The BAT46W-HE3-08 is designed as a power electronics rectifier and is particularly well-suited for applications in fields such as lighting, motor control, AC-DC power supplies, and UPS systems. The device has a maximum continuous forward operating current of 3A and a maximum forward voltage drop of 1.1V. It is rated for a peak reverse voltage of 200V and a surge reverse voltage of 400V.

The device can serve as a bridge rectifier, as it contains two sets of four electrodes in reverse configuration. This allows for unidirectional current flow, enabling efficient power conversion from alternating current (AC) to direct current (DC). It is also convenient for circuit applications, since the device’s size is small and its packaging can be perfectly fitted on circuit boards.

Working Principle

The BAT46W-HE3-08 is constructed of two sets of four electrodes that are internally stacked in ‘reverse’ configuration. The electrodes are made of a special alloy which enables them to act as a rectifying element in the device. The electrode pairs work to assist in achieving unidirectional current flow.

When voltage is applied to the device, the positively charged side of the rectifier attracts the electrons in the circuit and forms an electrical field. This electrical field forces the electrons to pass through the device, and results in unidirectional current flow. This is known as the forward biasing of the device.

Once the device is forward biased, the current passes through the device. During this period, the electrons are collected by the negative side of the rectifier and are then removed from the circuit, causing the current to flow in a single direction.

Once the power is removed from the device, the forward bias is removed and the device is no longer making a complete circuit, thus the current cannot flow. This process is called reverse biasing the device. When this occurs, current flow is blocked and the device effectively behaves like an open wire.

Conclusion

The BAT46W-HE3-08 is a single diode rectifier that is designed specifically for power conversion applications. It is designed with two sets of four electrodes in reverse configuration, which allows it to achieve high levels of conversion efficiency. By properly applying power to the device, it can be used to achieve efficient power conversion from AC to DC.
