BR82

Bridge Rectifier Overview

The GeneSiC Semiconductor BR82 is a single-phase silicon bridge rectifier housed in the BR-8 package. It supports a repetitive peak reverse voltage (VRRM) of 200 V, with corresponding RMS and DC blocking voltages of 140 V and 200 V, respectively. The device delivers a maximum average forward rectified current (IO) of 8.0 A at a case temperature of 50 °C. It withstands a peak forward surge current (IFSM) of 250 A under half-sine wave conditions. Key electrical parameters include a maximum instantaneous forward voltage drop (VF) of 1.1 V per bridge element at 4.0 A, and a maximum DC reverse current (IR) of 10 μA at rated voltage and 25 °C.

Bridge Rectifier Feature Summary

• Low forward voltage drop for improved efficiency
• Low leakage current characteristics
• Not ESD sensitive

Bridge Rectifier Applications

• Printed circuit board mounting applications
• General purpose AC to DC conversion
• Power supply input stages

Bridge Rectifier Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm exact ratings and package dimensions. Ensure compatibility with existing thermal management solutions, as the 8.0 A rating is specified at a case temperature of 50 °C. Confirm that the BR-8 package mounting style aligns with the mechanical design requirements of the target assembly.

Bridge Rectifier Selection Notes

Select this component when a 200 V reverse voltage rating and 8 A continuous current capability are required in a through-hole configuration. Consider the 1.1 V forward voltage drop for power loss calculations at the expected operating current. Verify that the 250 A surge current rating meets the inrush requirements of the specific circuit application.

Bridge Rectifier Part Context

The BR82 belongs to the BR805 thru BR84 series of single-phase silicon bridge rectifiers from GeneSiC Semiconductor. This family utilizes the BR-8 molded plastic package designed for through-hole mounting via #6 screw holes. The series covers voltage ratings from 50 V to 400 V while maintaining an 8.0 A current capacity across all variants.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 200 V VRRM, 8.0 A IO, and BR-8 package footprint. Verify pinout compatibility and thermal resistance characteristics before substitution.
