DFL1514S-E3/45

Bridge Rectifier Overview

The DFL1514S-E3/45 is a low profile miniature glass passivated single-phase surface mount bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the DFS case style and provides an average forward output rectified current of 1.5 A at an ambient temperature of 40 °C. The device supports maximum repetitive peak reverse voltages ranging from 50 V to 1000 V across the series, with a peak forward surge current capability of 50 A. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V per diode at 1.5 A and a maximum DC reverse current of 5 μA at rated blocking voltage. Operating junction and storage temperatures range from -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Low profile design with a typical height of 2.5 mm for compact mounting
• Glass passivation provides electrical isolation and protection
• Meets MSL level 1 per J-STD-020 standards for moisture sensitivity
• UL recognized under file number E54214

Bridge Rectifier Applications

• AC/DC bridge full wave rectification for switch mode power supplies (SMPS)
• Lighting ballast circuits
• Battery chargers and home appliances
• Office equipment and telecommunication applications

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and E3 suffix adherence to ensure lead-free status and whisker test compliance. Validate package integrity upon receipt to prevent damage to the low profile DFS casing during automated placement processes.

Bridge Rectifier Selection Notes

Select based on required reverse voltage rating within the 50 V to 1000 V range and thermal management needs. Ensure PCB layout accommodates the DFS footprint dimensions. Consider derating curves for ambient temperatures exceeding 40 °C to maintain the 1.5 A current rating safely.

Bridge Rectifier Part Context

This component belongs to the DFL15005S through DFL1510S family of low profile miniature bridge rectifiers. The series shares identical mechanical dimensions and electrical performance profiles, differentiated primarily by their maximum repetitive peak reverse voltage ratings. The E3 suffix indicates RoHS compliance and halogen-free construction.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same Vishay series include DFL1506S-E3/45, DFL1508S-E3/45, and DFL1510S-E3/45, provided the reverse voltage requirements are met. Cross-manufacturer replacements must match the DFS package outline and 1.5 A current rating.
