DF08S-E3/77

Bridge Rectifier Overview

The Vishay DF08S-E3/77 is a single-phase bridge rectifier from the DF series, designed for surface-mount applications. It features a DFS (4-SMD,鸥翼) package with four pins. The device supports a peak repetitive reverse voltage (Vrrm) of 800 V and an average forward rectified current (Io) of 1 A. Key electrical parameters include a maximum forward voltage (Vf) of 1.1 V at 1 A, a peak non-repetitive forward surge current (Ifsm) of 30 A, and a maximum reverse leakage current (Ir) of 5 µA at 800 V. It operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Surface-mount DFS package design for automated PCB assembly
• High thermal stability with extended operating temperature range
• Lead-free construction compliant with RoHS directives

Bridge Rectifier Applications

• General-purpose AC-to-DC power supply circuits
• Adapter and charger input stages
• Low-power industrial control rectification

Bridge Rectifier Procurement Notes

Verify the specific suffix /77 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to integration. Ensure component authenticity by sourcing from authorized distributors only. Check for any recent Product Change Notices (PCN) regarding material or process updates that may affect long-term availability or specifications.

Bridge Rectifier Selection Notes

Select this component for designs requiring 800 V reverse voltage blocking in a compact SMD form factor. Compare Vf and Ir characteristics against alternative bridge rectifiers to ensure compatibility with efficiency targets. Verify that the DFS footprint matches the target PCB layout constraints. Consider thermal management requirements given the small package size and 1 A current rating.

Bridge Rectifier Part Context

This part belongs to Vishay's DF series of miniature bridge rectifiers, which are optimized for space-constrained surface-mount applications. The series offers various voltage ratings (e.g., 400 V, 600 V, 800 V, 1000 V) while maintaining consistent mechanical dimensions and electrical performance profiles across variants.

Bridge Rectifier Replacement Considerations

Direct substitutes include other Vishay parts in the same series with different voltage ratings, such as DF04S-E3/77 (400 V) or DF10S-E3/77 (1000 V), provided the voltage margin is sufficient. Cross-brand replacements must match the DFS package outline, 1 A current rating, and 800 V minimum reverse voltage specification.
