DF04S-T

Bridge Rectifier Overview

The DF04S-T is a single-phase bridge rectifier manufactured by Diodes Incorporated, designed for surface-mount applications in the DF-S package. It features a peak repetitive reverse voltage of 400 V and an average rectified output current of 1 A. The device exhibits a forward voltage drop of 1.1 V at 1 A and a maximum reverse leakage current of 10 µA at 400 V. It supports a non-repetitive peak forward surge current of 50 A and operates within a junction temperature range of -65°C to 150°C. The component complies with RoHS3 standards and has a moisture sensitivity level of 1.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact 4-SMD鸥翼 (DF-S) package for automated assembly
• Standard silicon technology providing reliable rectification for general-purpose power supplies
• High thermal stability allowing operation up to a 150°C junction temperature

Bridge Rectifier Applications

• AC-DC conversion in low-power adapter circuits
• Bridge rectification in consumer electronics power stages
• General-purpose DC power supply input stages

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as the base part number corresponds to multiple configurations including tape-and-reel, cut-tape, and Digi-Reel formats. Confirm RoHS3 compliance status and check for recent product change notifications regarding manufacturing site or material updates before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select this component when a 1 A current rating and 400 V reverse voltage are required in a surface-mount form factor. Ensure the PCB footprint matches the DF-S package dimensions. Consider the 1.1 V forward voltage drop for efficiency calculations and verify that the 50 A surge capability meets the inrush current requirements of the target circuit design.

Bridge Rectifier Part Context

This part belongs to the DF04 series of single-phase bridge rectifiers from Diodes Incorporated. The 'T' suffix typically indicates tape-and-reel packaging, distinguishing it from bulk tube variants like the DF04S. It shares electrical characteristics with other members of the family but differs in peak reverse voltage ratings compared to higher-voltage variants such as the DF08S-T.

Bridge Rectifier Replacement Considerations

The SDB107-TP from Micro Commercial Components is documented as a similar replacement option. Verify pinout compatibility and ensure the substitute meets the 400 V and 1 A electrical requirements.
