Diodes are electronic components used to allow current to flow in one direction. Rectifiers are diodes that allow current to flow only in one direction. Arrays are a collection of rectifiers in a single package. The BAS40-04,215 rectifier array consists of four rectifiers in a single module designed to handle high current-handling duties and to ensure a reliable current-path.

Application Field

The BAS40-04,215 is specifically designed for use in high-current applications. Examples include switching power supplies and AC-DC converters for need for high-speed diode rectification. The fast switching time of the rectifier array allows for good EMC performance. The high reverse voltage rating of up to 400V makes it suitable for use in applications where a high peak reverse voltage is likely. Additionally, the array has an integrated snubber/EMI circuit for EMI reduction.

Working Principle

The BAS40-04,215 rectifier array consists of four Schottky rectifiers in a common-cathode configuration. This means that each rectifier has its own anode terminals, while all of the cathodes are connected together. When current flows in the forward direction, each rectifier conducts electricity and current flows through the entire array. However, when the current is reversed, each rectifier blocks the current, and no current is allowed to pass through the array.

The main advantages of this configuration are fast switching times and high current-handling capabilities. The fast switching times help reduce EMI emissions and improve power efficiency by allowing for higher switching frequency. Additionally, the high current-handling capabilities allow for increased efficiency and power handling capability.

Conclusion

The BAS40-04,215 rectifier array is designed for use in high-current applications where fast switching times and high current-handling capabilities are needed. The integrated snubber/EMI circuit helps reduce EMI emissions and the high peak reverse voltage rating makes it suitable for use in many high-power applications. The fast switching times help improve efficiency, and the high current-handling capability allows for higher efficiency and power handling capability.
