VB30202C-M3/8W Discrete Semiconductor Products

Diodes are electrical components which allow current to flow in one direction and block it in the opposite direction. Rectifiers are a special type of diodes which convert alternating current (AC) to direct current (DC). An array of rectifiers refers to a specialized circuit composed of several rectifiers connected in such a way that it can be used as an efficient, managed power source. The VB30202C-M3/8W device is an example of a rectifier array.

Applications

The VB30202C-M3/8W rectifier array is a low-power, low-voltage device commonly used in consumer goods, such as phones and tablets, power adapters, and various automotive applications. Its low voltage and low power consumption make it an ideal choice for applications that require steady and efficient power. This device is also well-suited for use as a part of an impedance electrically-controlled (EC) circuit.

Working Principle

The VB30202C-M3/8W rectifier array acts as a bridge between AC and DC power sources. The device is composed of two Schottky diodes alongside four, closely-located, general-purpose configurable power MOSFETs. The two Schottky diodes, connected in parallel, are designed to control the flow of alternating current. When the input voltage is incoming, the two Schottky diodes direct the current to the four power MOSFETs. These devices, in turn, function as a switch, ensuring that the voltage remains regulated, and that the normal current flow is maximized. The four power MOSFETs also help increase power efficiency by eliminating power losses associated with rectifier reverse conduction and reducing the power demand.
