GBU8M-E3/45

Overview

The GBU8M-E3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 8 A. The device supports a peak non-repetitive forward surge current of 200 A at a single half-sine wave. Electrical characteristics include a maximum forward voltage drop of 1 V and a reverse leakage current of 5 μA. It operates within a junction temperature range of -55°C to +150°C. The component utilizes a glass-passivated silicon construction housed in a GBU surface-mount package with dimensions of 22.3 mm length, 18.8 mm height, and 3.56 mm width.

Feature Summary

• Glass-passivated silicon die provides protection against mechanical stress and ensures stable electrical performance under varying thermal conditions.
• Surface-mount GBU package design facilitates automated assembly processes and efficient PCB space utilization for high-current applications.

Applications

• General-purpose AC-to-DC power supply conversion circuits
• Battery charging systems requiring high reverse voltage tolerance

Procurement Notes

Verify the specific suffix designation during procurement to ensure correct packaging configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure storage conditions align with moisture sensitivity level requirements to maintain device reliability throughout the manufacturing process.

Selection Notes

Select this component when circuit designs demand a 1000 V reverse voltage rating combined with an 8 A continuous current capacity in a surface-mount format. Evaluate thermal management requirements based on the specified junction temperature limits and forward voltage characteristics. Compare physical footprint constraints against available PCB real estate to confirm compatibility with the GBU package dimensions.
