DF02SA-E3/77

Bridge Rectifier Overview

The DF02SA-E3/77 is a single-phase bridge rectifier from Vishay’s DF series, designed for surface-mount applications. It features a DFS (4-SMD,鸥翼) package with four terminals. The device supports a peak repetitive reverse voltage of 200 V and an average forward rectified current of 1 A. Key electrical parameters include a maximum forward voltage of 1.1 V at 1 A and a peak non-repetitive forward surge current capability of 30 A. The component operates within a junction temperature range of -55°C to 150°C.

Bridge Rectifier Feature Summary

• Surface-mount construction in a compact DFS package suitable for automated PCB assembly
• High surge current handling capability for transient protection
• Lead-free construction compliant with RoHS directives

Bridge Rectifier Applications

• General-purpose AC to DC conversion circuits
• Power supply input stages
• Bridge rectification in low-power electronic devices

Bridge Rectifier Procurement Notes

Verify the specific suffix /77 corresponds to tape-and-reel packaging when ordering. Confirm RoHS compliance status as required by project specifications. Ensure the 200 V rating meets the circuit's peak inverse voltage requirements. Check for any recent product change notices regarding manufacturing location or material composition updates.

Bridge Rectifier Selection Notes

Select this component where space constraints necessitate a surface-mount bridge rectifier. The 1 A current rating suits low-power applications. Compare thermal performance against through-hole alternatives if heat dissipation is critical. Ensure the 200 V reverse voltage provides adequate margin for the AC input line voltage.

Bridge Rectifier Part Context

This part belongs to the Vishay DF series of miniature bridge rectifiers. The series offers various voltage ratings including 100 V, 200 V, 400 V, and 600 V variants. The DFS package provides a small footprint compared to traditional through-hole options, facilitating dense PCB layouts.

Bridge Rectifier Replacement Considerations

Direct substitutes include other Vishay parts in the same series with identical current ratings but different voltage ratings, such as DF01SA-E3/77 (100 V) or DF04SA-E3/77 (400 V). Cross-manufacturer equivalents in the DFS package should be verified for pinout compatibility and thermal characteristics.
