DF1508S-E3/45

Bridge Rectifier Overview

The DF1508S-E3/45 is a miniature glass-passivated single-phase surface-mount bridge rectifier manufactured by Vishay General Semiconductor. It provides an average forward output rectified current of 1.5 A at 40 °C and supports a maximum repetitive peak reverse voltage of 800 V. The device features a peak forward surge current capability of 50 A and operates within a junction temperature range of -55 to +150 °C. Electrical characteristics include a maximum instantaneous forward voltage drop of 1.1 V at 1.5 A and a maximum DC reverse current of 5 µA at rated blocking voltage. It utilizes the DFS case style with matte tin-plated leads.

Bridge Rectifier Feature Summary

• Meets UL flammability rating V-0 for molding compound
• Suitable for automated placement processes
• Compliant with JESD 201 class 1A whisker test requirements

Bridge Rectifier Applications

• AC/DC bridge full wave rectification in switch-mode power supplies
• Lighting ballast circuits
• Battery chargers and home appliances
• Telecommunication equipment

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability data required by your quality management system. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering.

Bridge Rectifier Selection Notes

Select this component when a compact surface-mount bridge rectifier is required for high-voltage applications up to 800 V. Verify that the PCB copper pad dimensions match the recommended 13 mm x 13 mm layout for optimal thermal performance. Consider the 1.5 A current rating relative to ambient operating temperatures and derating curves.

Bridge Rectifier Part Context

This part belongs to the DF15005S through DF1510S series, which share identical physical dimensions and electrical characteristics except for the reverse voltage rating. The E3 suffix indicates RoHS compliance and lead-free terminals, while the /45 package code specifies tube delivery. The DFS package allows for space-efficient designs in consumer electronics and industrial control systems.

Bridge Rectifier Replacement Considerations

Direct substitutes within the same series include DF1506S-E3/45 (600 V) and DF1510S-E3/45 (1000 V), provided voltage ratings align with circuit requirements. Cross-manufacturer equivalents must be verified for matching current ratings, package footprint, and thermal resistance values.
