BR31

Bridge Rectifier Overview

The GeneSiC Semiconductor BR31 is a single-phase silicon bridge rectifier housed in a BR-3 through-hole package. It features a repetitive peak reverse voltage of 100 V and supports a maximum forward rectified current of 3 A. The device exhibits a maximum forward voltage drop of 1.05 V at 1.5 A and a maximum reverse current of 10 µA at rated DC blocking voltage. It withstands a peak forward surge current of 60 A under half-sine wave conditions. Thermal resistance from junction to ambient is 18 °C/W, with an operating temperature range of -40 to 125 °C.

Bridge Rectifier Feature Summary

• Glass passivated silicon construction for reliability
• Low forward voltage drop characteristics
• High surge overload rating capability
• ESD insensitive design

Bridge Rectifier Applications

• Switching power supplies
• Industrial auto-equipments
• Home appliances
• Office devices

Bridge Rectifier Procurement Notes

Verify the specific manufacturer designation on the component marking against official GeneSiC Semiconductor documentation. Confirm that the BR-3 package dimensions and terminal configuration match the required PCB layout specifications before integration into the design.

Bridge Rectifier Selection Notes

Select this component when a 100 V reverse voltage rating and 3 A continuous current are required in a compact BR-3 package. Ensure the thermal management strategy accounts for the 18 °C/W junction-to-ambient thermal resistance to maintain operation within the specified temperature limits.

Bridge Rectifier Part Context

The BR31 belongs to the BR305 thru BR34 series of single-phase glass passivated silicon bridge rectifiers. This family offers various voltage ratings from 50 V to 400 V while maintaining a consistent 3 A current capacity and BR-3 package form factor for standardized mounting solutions.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other BR31 equivalents from different manufacturers offering identical 100 V, 3 A specifications in the BR-3 package. Verify pinout compatibility and thermal performance metrics before substitution.
