GBU8M-E3/51

Bridge Rectifier Overview

The GBU8M-E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes glass passivation for junction protection and is housed in a GBU surface-mount package with four pins. The device supports a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 8 A. 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 uA. It operates within a temperature range of -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivation provides stable leakage characteristics and robust mechanical strength for the junctions.
• Surface-mount GBU package design facilitates automated assembly and efficient PCB space utilization.

Bridge Rectifier Applications

• AC-DC power supply circuits
• Battery chargers
• General-purpose rectification in industrial equipment

Bridge Rectifier Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact rating variants. Ensure the component matches the required voltage and current specifications for the target application. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before procurement.

Bridge Rectifier Selection Notes

Select this component when a high-voltage (1000 V) surface-mount bridge rectifier is required. The 8 A current rating suits moderate power applications. Consider thermal management requirements due to the 1 V forward voltage drop at full load. Verify that the GBU footprint aligns with the PCB layout constraints.

Bridge Rectifier Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Vishay. The series offers various voltage ratings and current capacities in a standardized surface-mount package. The GBU8M variant specifically targets high-voltage applications requiring reliable performance in compact designs.

Bridge Rectifier Replacement Considerations

GBU8M-E3/45 is listed as an alias for this part number in distributor records. Verify pinout compatibility and identical electrical ratings before substitution. Other GBU series parts may serve as alternatives if voltage and current ratings are sufficient.
