BU2506-E3/45

Bridge Rectifier Overview

The BU2506-E3/45 is a single-phase bridge rectifier from Vishay General Semiconductor, utilizing enhanced isoCink+ technology. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified forward current of 25 A at a case temperature of 60 °C. The device has a non-repetitive peak forward surge current rating of 300 A. Typical junction capacitance is 125 pF. Maximum instantaneous forward voltage is 1.05 V at 12.5 A and 25 °C. Operating junction and storage temperature range spans from -55 °C to +150 °C. The component is housed in a thin single-in-line BU package with matte tin plated leads.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Suffixes such as /45 or /51 indicate different packaging formats like tubes or paper trays. Confirm RoHS compliance status based on the base part number designation (E3 or M3). Ensure that the selected variant matches the required delivery mode and unit weight specifications for your assembly process.

Bridge Rectifier Selection Notes

Select the BU2506 variant specifically when a 600 V reverse voltage rating is required, distinguishing it from the 800 V and 1000 V options within the same series. Consider the thermal resistance values when designing heatsinking solutions, as performance varies significantly between free air and mounted conditions. Validate the forward voltage drop characteristics against your efficiency requirements at the expected operating current levels.

Bridge Rectifier Part Context

This component belongs to the BU2506, BU2508, and BU2510 family of enhanced isoCink+ bridge rectifiers manufactured by Vishay General Semiconductor. All variants share identical physical dimensions and electrical characteristics except for the maximum repetitive peak reverse voltage ratings. The series is designed for general-purpose rectification in compact electronic assemblies requiring high current handling capabilities.

Bridge Rectifier Replacement Considerations

Direct substitutes within the Vishay lineup include the BU2508-E3/45 and BU2510-E3/45, which offer higher voltage ratings of 800 V and 1000 V respectively while maintaining the same current and package specifications.
