GBU8M-M3/45

Overview

The GBU8M-M3/45 is a single-phase bridge rectifier from Vishay Semiconductors, utilizing glass passivation for cathode isolation. It features an 8 A average forward current rating and a 1000 V repetitive peak reverse voltage (Vrrm). The device employs a GBU surface-mount package with solder pad termination. Key electrical parameters include a maximum non-repetitive peak forward surge current of 200 A, a peak forward voltage of 1 V, and a maximum reverse current of 5 μA. It operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivation provides stable blocking voltage performance and low leakage current characteristics.

Applications

• General-purpose AC to DC power supply rectification
• Adapters and chargers requiring high-voltage isolation

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm compliance status and packaging details. Confirm that the M3 designation aligns with RoHS requirements. Ensure the GBU footprint matches the target PCB design before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for high-voltage applications up to 1000 V. The GBU package offers robust mechanical stability compared to smaller form factors. Verify thermal management capabilities for continuous 8 A operation in the intended enclosure environment.

Part Context

This part belongs to the GBU8 series of single-phase bridge rectifiers. The series includes variants with different voltage ratings, such as GBU8B (100 V), GBU8D (200 V), GBU8F (400 V), GBU8G (600 V), GBU8K (800 V), and GBU8M (1000 V). All share identical current and package specifications.

Replacement Considerations

GBU8M-E3/45 serves as a verified equivalent within the same product family. Both parts share identical electrical ratings and physical dimensions. Verify pinout compatibility during substitution.
