BR3500

Bridge Rectifier Overview

The EIC Semiconductor BR3500 is a single-phase silicon bridge rectifier rated for 35 Amperes average forward current and 50 Volts maximum repetitive peak reverse voltage. It features a molded plastic case with an integrated metal heatsink, utilizing plated .25-inch Faston terminals for through-hole mounting. The device supports a junction temperature range of -40 to +150 °C and offers a typical thermal resistance from junction to case of 1.5 °C/W. Electrical characteristics include a maximum forward voltage of 1.1 V at 17.5 A and a peak forward surge current capability of 400 A.

Bridge Rectifier Feature Summary

• Integrated metal heatsink within the encapsulation for efficient thermal dissipation
• Rated isolation voltage of 2000 V for enhanced safety
• Lead-free and RoHS compliant construction

Bridge Rectifier Applications

• General purpose AC to DC power supply rectification
• Industrial equipment requiring high surge current handling
• Battery charging circuits

Bridge Rectifier Procurement Notes

Verify the specific part number suffix against the manufacturer's datasheet to confirm the exact voltage rating, as the BR3500 series spans multiple voltage options. Confirm that the procurement documentation explicitly states compliance with RoHS standards and lead-free material requirements. Ensure the package type matches the GBPC or equivalent flange-mount specification with Faston terminals for proper integration into the target circuit board design.

Bridge Rectifier Selection Notes

Select this component when a 35 A continuous current rating and 50 V blocking voltage are required in a robust, heatsink-integrated package. Consider the 1.5 °C/W junction-to-case thermal resistance for heat sink sizing calculations. Verify that the application load is resistive or inductive; if capacitive loads are present, derate the forward current by 20% to ensure reliable operation within the specified thermal limits.

Bridge Rectifier Part Context

The BR3500 belongs to the BR3500-BR3512 family of silicon bridge rectifiers manufactured by EIC Semiconductor. This series provides standardized current ratings of 35 Amperes across various voltage options ranging from 50 V to 1200 V. The components share identical mechanical dimensions and thermal characteristics, differing primarily in their peak reverse voltage capabilities to suit diverse power supply designs.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers' 35 A bridge rectifiers featuring integrated heatsinks and Faston terminals. Verify that substitute parts match the 50 V VRRM rating, 1.1 V VF maximum, and 400 A IFSM surge current specifications. Ensure the replacement package maintains the same mounting hole spacing and terminal configuration for direct PCB compatibility.
