BR1504

Bridge Rectifier Overview

The BR1504 is a silicon bridge rectifier from the EIC Semiconductor BR1500 series, designed for general-purpose power conversion. It features a maximum average forward current of 15 A at a case temperature of 55°C and supports a maximum repetitive peak reverse voltage of 400 V. The device exhibits a low forward voltage drop of 1.1 V at 7.5 A and handles a peak forward surge current of 300 A under JEDEC testing conditions. Electrical characteristics are maintained within an operating junction temperature range of -40°C to +150°C, with a typical thermal resistance of 1.9°C/W.

Bridge Rectifier Feature Summary

• High current capability with integrated metal heatsink for efficient thermal management
• Low reverse current and low forward voltage drop for improved efficiency
• Rated isolation voltage of 2000 V for enhanced safety
• Polarity symbols marked on the molded plastic case for easy identification

Bridge Rectifier Applications

• General purpose full-wave rectification in AC-DC power supplies
• Battery charging circuits requiring high surge current tolerance
• Industrial equipment power modules utilizing bolt-down mounting

Bridge Rectifier Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package dimensions and terminal plating details match the provided mechanical data. Ensure ordering suffixes align with specific environmental or packaging requirements defined by the supplier. Request test reports for critical electrical parameters if used in high-reliability applications.

Bridge Rectifier Selection Notes

Select the BR1504 when a 400 V reverse voltage rating is required alongside a 15 A continuous current capacity. Consider the 300 A surge capability for inductive loads or capacitive input filters. Evaluate the bolt-down mounting style and faston terminals for compatibility with existing heat sink infrastructure and PCB layouts.

Bridge Rectifier Part Context

The BR1504 belongs to the BR1500-BR1510 family of silicon bridge rectifiers manufactured by EIC Semiconductor. This series shares common mechanical and thermal characteristics, differing primarily in their maximum repetitive peak reverse voltage ratings. The BR1504 specifically provides a 400 V blocking voltage, positioning it between lower-voltage variants like the BR1502 and higher-voltage options such as the BR1506.

Bridge Rectifier Replacement Considerations

Direct substitutes include other 15 A, 400 V bridge rectifiers with compatible mounting styles and terminal configurations. Verify that alternative components meet the same surge current (IFSM) and thermal resistance (RθJC) specifications to ensure equivalent performance in the target application.
