DF08S1

Bridge Rectifier Overview

The onsemi DF08S1 is a single-phase bridge rectifier designed for surface-mount applications. It features an average forward current rating of 1 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a 4-SDIP package with鸥翼 (gull-wing) leads, measuring 8.51 mm in length, 6.5 mm in width, and 2.6 mm in height. Electrical characteristics include a maximum forward voltage of 1.1 V at 1 A and a reverse leakage current of 3 µA at 800 V. The component supports a junction temperature range from -55°C to +150°C and offers a non-repetitive peak forward surge current capacity of 35 A.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact 4-SDIP package suitable for automated assembly
• High voltage blocking capability up to 800 V for robust reverse protection
• Extended thermal operating range supporting high-temperature environments

Bridge Rectifier Applications

• General-purpose AC-to-DC power supply circuits
• Bridge rectification in low-power electronic devices
• Adapters and chargers requiring surface-mount topology

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging configuration. Confirm RoHS compliance status and material declarations prior to integration. Check for any recent Product Change Notifications regarding assembly or design modifications that may affect qualification.

Bridge Rectifier Selection Notes

Select this component when a 1 A current rating and 800 V reverse voltage are required in a surface-mount form factor. Ensure the PCB footprint matches the 4-SDIP dimensions. Consider the 1.1 V forward voltage drop for thermal management calculations in the final application design.

Bridge Rectifier Part Context

This part belongs to the DF08 series of bridge rectifiers from onsemi. It shares the same physical package and general electrical architecture as variants like the DF04S1, differing primarily in the peak reverse voltage rating. The DF08S1 specifically targets applications requiring higher voltage isolation compared to lower-rated siblings within the same family.

Bridge Rectifier Replacement Considerations

Direct pin-compatible substitutes within the same series include the DF04S1 for lower voltage requirements. Verify that alternative manufacturers' components match the 4-SDIP outline and electrical parameters before substitution.
