VS-STPS40L15CWPBF Application Field and Working Principle

VS-STPS40L15CWPBF is a Rectifier Array produced by STMicroelectronics, that is widely used in rectifying and automotive applications. It is a 4-pin, 30A Schottky Rectifier Array. It provides the best performance in power systems.

Application Field

In automotive applications, the VS-STPS40L15CWPBF rectifier array is a suitable choice for applications that involve efficiently converting alternating current (AC) to direct current (DC) and providing a regulated voltage output. It is suitable for various purposes like battery charging, engine start systems, electric powertrain control and onboard DC-DC conversion.This product has a low saturation voltage, VF, of 0.51 V (typical) at 30 A of load current. Therefore, VS-STPS40L15CWPBF can guarantee a high efficiency in applications where VF is normally the bottleneck. This SMA package, by virtue of its small size, is suited for automotive and space-saving applications.

Working Principle

The VS-STPS40L15CWPBF is a 4-pin, 30A Schottky Rectifier Array consisting of two internal 30A, 600V power Schottky diodes connected in an upper/lower configuration. The goal is for it to receive a low-level AC voltage, convert it to pulsating DC, and then use the external power source to convert the pulsating DC to regulated DC. The internal two 600V, 30A Schottky Diodes are connected in an upper/lower configuration, resulting in an effective peak current rating of 60A. The Schottky diodes are also arranged in an isolated powerArray configuration, helping to minimize PC board size, reduce thermal dissipation and improve system safety. Voltage-clamp control, dynamic avalanche insertion and temperature-dependent control features ensure that the VS-STPS40L15CWPBF meets the rigorous requirements of automotive applications. By controlling the avalanche of the diodes in the rectifier array, this product can ensure robustness of overcurrent and withstand reverse bias in both directions. In addition, the VS-STPS40L15CWPBF is AEC-Q101 qualified and RoHS compliant. It is capable of supporting a maximum peak reverse voltage of 15V, allowing engineers to design and implement reliable, efficient and cost-effective power systems. In summary, the VS-STPS40L15CWPBF is an ideal rectifier array for various applications that require turning AC input into a steady DC output, including automotive applications. By combining outstanding properties such as high efficiency and low saturation voltage, this product is ideal for various power electronics requirements.
