DF1504ST-G

Bridge Rectifier Overview

The DF1504ST-G is a single-phase bridge rectifier manufactured by Comchip Technology, utilizing silicon planar epitaxial construction. It features an average forward rectified current of 1.5 A and a maximum repetitive peak reverse voltage of 400 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and a low reverse leakage current of 5 µA. Designed for surface-mount applications in the DFS-4 package, it supports a maximum non-repetitive peak forward surge current of 50 A. The component operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical ratings and compliance status. Confirm RoHS directive adherence through certified datasheets prior to integration. Ensure compatibility with existing PCB footprints and soldering profiles during procurement planning.

Bridge Rectifier Selection Notes

Select this component when a compact surface-mount bridge rectifier is required for 400V applications. Compare the DFS-4 footprint dimensions against available board space. Evaluate thermal management requirements based on the 1.5A continuous current rating and ambient operating conditions.

Bridge Rectifier Part Context

This part belongs to the DF150xS series of surface-mount bridge rectifiers from Comchip Technology. It shares the same physical DFS-4 package and general structural characteristics with other variants in the family, differing primarily in voltage ratings such as 200V or 600V options.

Bridge Rectifier Replacement Considerations

The Vishay General Semiconductor DF1504S-E3/45 is a documented direct substitute offering identical electrical specifications and the DFS surface-mount package format.
