Diodes - Rectifiers - Arrays: VB30100C-E3/4W application field and working principle

Rectifiers are the most frequently used power semiconductors in numerous industrial and consumer applications. A wide variety of diodes and rectifiers are available, with different voltages and current ratings. One such type of rectifier is VB30100C-E3/4W, whose usage and features are discussed in this paper.

Application Field

The VB30100C-E3/4W diode array is mainly used in flyback switching power supply, forward converter power supply and other power circuits, usually combined with Schottky diodes and thyristors. It is suitable for electronic equipment with a power input of 300W or less. This rectifier can also be used in low-voltage and high-current DC power supplies, such as the rectification of AC voltage in power shop and electric welding machine.

Working Principle

The VB30100C-E3/4W diode array mainly consists of three high power diodes which allow current to flow in one direction only and block current in the opposite direction. It works by allowing the current to flow in one direction during the positive half cycle of the AC voltage and blocks the current during the negative half cycle of the AC voltage. The three diodes are connected in series, thus forming a bridge rectifier. The rectified output from the bridge rectifier is full wave rectification. This diode array is a compact and economical solution to rectification of AC signals.
