Description

SB3A0 is 100V, 3A, Schottky Barrier Rectifier. A Schottky barrier rectifier is a type of rectifier that is used to convert alternating current (AC) to direct current (DC).

The Schottky barrier rectifier is a two-terminal device that consists of a metal-semiconductor (metal-Schottky) junction, with the metal serving as the anode and the semiconductor serving as the cathode. When an AC voltage is applied to the device, a rectifying action takes place at the Schottky barrier, causing a current flow in only one direction. This results in a DC output voltage that is proportional to the amplitude of the AC input voltage.

One of the advantages of the Schottky barrier rectifier is its fast switching speed, which makes it suitable for high-frequency applications. It also has a low forward voltage drop, which results in low power losses and high efficiency. Additionally, the Schottky barrier rectifier has a

Description

The DBF10 is 1A, Single-Phase Bridge Rectifier. This is an electronic circuit that converts an alternating current (AC) input into a direct current (DC) output using a bridge configuration of diodes. The purpose of a bridge rectifier is to ensure that the voltage is always positive, even though the input voltage waveform may be alternating in direction. This makes it useful in applications such as power supplies, battery charging, and motor control where a DC voltage is required.

The basic operation of a bridge rectifier is to allow current to flow only in one direction, by using diodes to block any reverse current. The diodes are arranged in a bridge configuration, hence the name “bridge rectifier.” The AC voltage is applied to the diode bridge, and the resulting DC voltage is available at the output terminals.

Features

1. Plastic molded structure.

2. Peak reverse voltage : VRM=100 to 600V.
