DF08SA-E3/77

Bridge Rectifier Overview

The DF08SA-E3/77 is a Vishay General Semiconductor single-phase bridge rectifier from the DF series, designed for surface-mount applications. It features a DFS (4-SMD,鸥翼) package with dimensions of 8.51mm length, 6.5mm width, and 3.3mm height. The device supports a peak repetitive reverse voltage (Vrrm) of 800V and an average forward rectified current (If) of 1A. Key electrical parameters include a maximum forward voltage (Vf) of 1.1V at 1A, a non-repetitive peak forward surge current (Ifsm) of 30A, and a maximum reverse leakage current (Ir) of 5µA at 800V. 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 supporting operation up to 150°C junction temperature
• Standard silicon rectification technology for general-purpose applications

Bridge Rectifier Applications

• AC-DC power supply circuits
• General-purpose rectification in consumer electronics
• Low-power adapter designs

Bridge Rectifier Procurement Notes

Verify the specific suffix /77 indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Vishay documentation prior to integration. Ensure the 800V rating matches the circuit's peak inverse voltage requirements. Check for any recent product change notices affecting pinout or material composition.

Bridge Rectifier Selection Notes

Select this component for space-constrained designs requiring SMT mounting. The 1A current rating suits low-power applications. Compare the 800V blocking capability against system voltage spikes. Consider the 1.1V forward drop for efficiency calculations. Verify thermal management needs given the small DFS footprint.

Bridge Rectifier Part Context

This part belongs to Vishay's DF series of surface-mount bridge rectifiers. The series offers various voltage ratings including 100V, 200V, 400V, 600V, and 800V options. The DF08SA variant specifically provides 800V blocking capability. The 'E3' suffix denotes lead-free and halogen-free construction compliant with RoHS directives.

Bridge Rectifier Replacement Considerations

DF08S-E3/45: Direct functional substitute from Vishay in tube packaging. DF08S: Alternative from onsemi or Diodes Incorporated in similar DFS packages. Verify pin compatibility and thermal characteristics before substitution.
