BR3504W

Bridge Rectifier Overview

The BR3504W is a silicon bridge rectifier from the BR3500W series, rated for a maximum repetitive peak reverse voltage of 400 V and a maximum average forward current of 35 A at a case temperature of 55°C. It features a typical junction-to-case thermal resistance of 1.5°C/W and operates within a junction temperature range of -40 to +150°C. The device exhibits a maximum forward voltage drop of 1.1 V at 17.5 A and supports a peak forward surge current of 400 A.

Bridge Rectifier Feature Summary

• High current capability with integrated heatsink in molded plastic encapsulation
• Low forward voltage drop and low reverse current characteristics
• High reliability with UL94V-0 flame retardant epoxy and solderable terminals

Bridge Rectifier Applications

• General purpose power supply rectification
• Industrial equipment requiring high surge current tolerance
• Battery charging circuits

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revision status and package dimensions match specific design requirements. Ensure proper thermal interface material application during installation to maintain specified thermal performance.

Bridge Rectifier Selection Notes

Select based on required reverse voltage rating exceeding circuit peak inverse voltage. Consider derating forward current by 20% for capacitive loads. Evaluate thermal management needs against the 1.5°C/W junction-to-case resistance specification for optimal heat dissipation.

Bridge Rectifier Part Context

This component belongs to the BR3500W series of silicon bridge rectifiers manufactured by EIC Semiconductor Inc. The series includes variants with different voltage ratings ranging from 50 V to 1000 V while maintaining consistent current handling capabilities and mechanical specifications across all models.

Bridge Rectifier Replacement Considerations

BR3506W offers higher voltage rating (600 V) with identical current and thermal characteristics. BR3502W provides lower voltage rating (200 V) suitable for reduced voltage applications. Verify pinout compatibility and thermal resistance values when substituting.
