Diodes - Rectifiers - Arrays

The VS-40L15CWPBF is a single phase rectifier bridge array package from the VS-40LxxCWPBF series. This series of products are designed for general purpose rectification and for automotive applications, and integrate four Schottky diodes into a single package with a discrete heat sink.

Application Field

The VS-40L15CWPBF can be used as a replacement for traditional three phase rectifier bridges in automotive applications. Since it integrates four Schottky diodes into a single package, it offers improved power efficiency while also improving space savings. In addition, the VS-40L15CWPBF is also suitable for mains power rectification and other general purpose switching applications.

Working Principle

The VS-40L15CWPBF is a rectifier array package composed of four Schottky diodes. The diodes use the Schottky junction technology, which allows for high current and low forward voltage drops. The diodes are also designed for economy with wide conduction angles that reduce the power loss. The diodes are also connected to a common heat sink for improved thermal stability.

The VS-40L15CWPBF is connected to the main power supply. When the power supply voltage is below the forward voltage of the diodes, the current can flow from the power supply to the output. This process is known as rectification and is commonly used to obtain direct current (DC) from alternating current (AC). When the input voltage exceeds the forward voltage of the diodes, the current can flow back towards the power supply. This process is known as reverse current, and protects the output in the event of an over-voltage.

The heat sink used in the VS-40L15CWPBF helps to absorb and dissipate the heat generated during operation, ensuring the diodes remain within the specified operating temperature range. The heat sink also increases the power handling capability of the package.

Conclusion

The VS-40L15CWPBF is a single phase rectifier bridge array package designed for general purpose rectifier applications and automotive applications. It integrates four Schottky diodes into a single package with a discrete heat sink to improve power efficiency and space savings. The Schottky diodes have low forward voltage drops and wide conduction angles to reduce power loss. The heat sink improves thermal stability and allows for higher power handling capability. Therefore, the VS-40L15CWPBF is a cost effective solution for automotive and general purpose rectifier applications.
