BR86

Bridge Rectifier Overview

The GeneSiC Semiconductor BR86 is a single-phase silicon bridge rectifier designed for general-purpose power conversion applications. It features a maximum average forward rectified current (IO) of 8.0 A and offers selectable repetitive peak reverse voltage (VRRM) ratings ranging from 600 V to 1000 V, with the specific BR86 variant rated at 600 V. The device exhibits a maximum instantaneous forward voltage drop (VF) of 1.1 V at 4.0 A and supports a peak forward surge current (IFSM) of 250 A under half-sine wave conditions. Operating junction temperature ranges from -65 °C to +125 °C, while storage temperatures extend up to +150 °C.

Bridge Rectifier Feature Summary

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

Bridge Rectifier Applications

• General-purpose power supply circuits
• AC-DC conversion systems
• Industrial rectification modules

Bridge Rectifier Procurement Notes

Verify the specific voltage suffix corresponding to the required reverse voltage rating, as the BR8 series spans multiple voltage options. Confirm package compatibility with mounting hardware, specifically #6 screw holes. Ensure thermal management aligns with the specified Tc = 50 °C derating curves for continuous operation.

Bridge Rectifier Selection Notes

Select the BR86 when a 600 V blocking capability is required alongside an 8 A continuous current rating. Consider the BR88 or higher variants if system voltages exceed 600 V. Evaluate thermal dissipation requirements based on the 1.1 V forward voltage drop and ambient operating conditions to ensure junction temperature limits are not exceeded.

Bridge Rectifier Part Context

The BR86 belongs to the BR8 series of single-phase silicon bridge rectifiers manufactured by GeneSiC Semiconductor. This series provides standardized BR-8 package solutions with current ratings of 8 A and voltage options from 600 V to 1000 V. The components are designed for through-hole mounting and robust industrial environments.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 8 A current rating, 600 V minimum reverse voltage, and BR-8 package dimensions. Verify forward voltage and leakage current specifications to ensure equivalent performance in the target circuit.
