GBU6M-E3/51

Overview

The GBU6M-E3/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features a glass passivated junction and utilizes the GBU surface mount package. The device supports a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 6.0 A. Key electrical parameters include a maximum forward voltage drop of 1 V, a reverse leakage current of 5 µA, and a non-repetitive peak forward surge current of 175 A. It operates within a temperature range of -55°C to +150°C TJ.

Feature Summary

• Glass passivated junction structure provides high reliability and resistance to voltage transients.
• Surface mount GBU package design facilitates automated assembly and compact PCB layout.
• High thermal performance allows operation at junction temperatures up to 150°C.

Applications

• General purpose rectification in power supply circuits.
• Inverter and converter input stages.
• Freewheeling diode applications in motor drives.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for specific suffix variations that may indicate different packaging formats. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Selection Notes

Select this component when a 1000 V rating is required for single-phase bridge rectification. The GBU package is suitable for surface mount technology applications requiring high current density. Compare forward voltage drop specifications against system efficiency targets. Verify lead-free solderability if environmental regulations mandate specific termination materials.

Part Context

This part belongs to the Vishay GBU6 series of single-phase bridge rectifiers. The series offers various voltage ratings from 50 V to 1000 V while maintaining consistent mechanical dimensions. The E3 suffix indicates lead-free terminals compliant with EU directives. The M variant specifically denotes the 1000 V blocking capability within the product line.

Replacement Considerations

Cross-reference with other Vishay GBU6xxx-E3/51 variants for different voltage ratings. Verify pinout compatibility with existing PCB footprints. Ensure thermal management solutions support the 150°C junction temperature limit of equivalent components.
