BR1506

Bridge Rectifier Overview

The EIC Semiconductor BR1506 is a single-phase silicon bridge rectifier designed for high current applications. It features a maximum average forward rectified output current of 15 A at a case temperature of 55°C and a maximum recurrent peak reverse voltage of 600 V. The device exhibits a typical thermal resistance from junction to case of 1.9 °C/W, supporting efficient heat dissipation when mounted on an aluminum finned plate. Electrical characteristics include a maximum forward voltage of 1.1 V per diode at 7.5 A and a peak forward surge current capability of 300 A under JEDEC testing conditions.

Bridge Rectifier Feature Summary

• High current and surge current capabilities suitable for demanding power conversion loads
• Low forward voltage drop and low reverse leakage current for improved efficiency
• Robust mechanical construction with UL94V-0 rated flame retardant epoxy encapsulation
• Integrated metal heatsink design allowing direct bolt-down mounting for thermal management

Bridge Rectifier Applications

• General purpose AC to DC rectification in industrial power supplies
• Battery charging circuits requiring high surge tolerance
• DC motor drive systems utilizing resistive or inductive loads

Bridge Rectifier Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm that the terminal plating matches the .25-inch Faston requirement and ensure the package integrity remains intact without physical damage to the molded plastic housing before integration into the assembly process.

Bridge Rectifier Selection Notes

Select this component when a 600 V blocking voltage is required alongside a continuous 15 A load capacity. Ensure the application environment allows for adequate airflow or heatsinking to maintain the case temperature below 55°C for full current rating. Consider derating requirements if the load involves significant capacitive elements.

Bridge Rectifier Part Context

This part belongs to the BR1500 series, which includes variants ranging from 50 V to 1000 V reverse voltage ratings while maintaining a consistent 15 A current capability. The series shares identical mechanical dimensions and thermal characteristics, allowing for pin-compatible upgrades within the same family based solely on voltage requirements.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers' BR1506 equivalents such as those from SynSemi or New Jersey Semi-Conductor. Verify that substitute parts match the 15 A current rating, 600 V reverse voltage, and compatible terminal spacing to ensure seamless integration.
