DF04S1

Bridge Rectifier Overview

The onsemi DF04S1 is a single-phase bridge rectifier from the DF-S series, designed for surface-mount applications. It features a 4-SDIP package with dimensions of 8.51 mm in length, 6.5 mm in width, and 2.6 mm in height. The device supports an average forward current (If) of 1 A and withstands a peak repetitive reverse voltage (Vrrm) of 400 V. Key electrical parameters include a maximum forward voltage (Vf) of 1.1 V at rated current, a non-repetitive peak forward surge current (Ifsm) of 35 A, and a reverse leakage current (Ir) of 3 µA. It operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact SDIP-4L package suitable for automated placement
• High thermal stability with a maximum operating junction temperature of 150°C
• Robust surge handling capability with a 35 A peak non-repetitive forward surge current rating

Bridge Rectifier Applications

• General-purpose AC-to-DC conversion in low-power power supplies
• Bridge rectification in consumer electronics requiring surface-mount technology
• Adapter circuits for devices with moderate current requirements up to 1 A

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Check for end-of-life notices as availability may be limited. Ensure packaging specifications match production line requirements, noting historical reel quantities of 1,500 units.

Bridge Rectifier Selection Notes

Select this component when a 1 A continuous current rating and 400 V reverse voltage are required in a surface-mount format. Compare Vf characteristics against alternative bridge rectifiers to ensure efficiency targets are met. Verify that the 35 A surge rating aligns with inrush current demands in the target circuit design.

Bridge Rectifier Part Context

The DF04S1 belongs to the DF-S series of miniature glass-passivated single-phase surface mount bridge rectifiers manufactured by onsemi. This series is engineered for high-volume automated assembly processes. The part utilizes standard silicon planar technology to provide reliable rectification in space-constrained printed circuit board layouts.

Bridge Rectifier Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified sources. Consider equivalent models from other manufacturers only if they match the 1 A current, 400 V voltage, and SDIP-4L package constraints.
