GBU6M-M3/51

Overview

The GBU6M-M3/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors, utilizing glass passivated junction technology for enhanced reliability. It features a GBU surface-mount package with solder pad termination, designed for automated assembly processes. The device supports a maximum average forward rectified current of 6.0 A and offers a peak repetitive reverse voltage rating of 1000 V. Key electrical parameters include a maximum forward voltage drop of 1.0 V at rated current, a non-repetitive peak surge current capacity of 175 A, and a low reverse leakage current of 5 µA. The component operates within a temperature range of -55 °C to +150 °C junction temperature.

Feature Summary

• Glass passivated junction construction provides mechanical stress resistance and improved long-term stability compared to passivationless alternatives.
• Surface mount GBU package design enables efficient PCB space utilization and compatibility with standard SMD reflow soldering profiles.
• High thermal performance allows operation up to 150 °C junction temperature, supporting robust performance in demanding environments.

Applications

• AC-DC power supply circuits requiring high-voltage isolation and compact form factors
• Industrial control systems utilizing surface-mounted bridge rectification
• Consumer electronics adapters needing reliable 1000 V blocking capability

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout orientation and compliance status. Ensure that the M3 designation aligns with required halogen-free specifications for your manufacturing process. Cross-reference the GBU package dimensions with your PCB footprint library to guarantee accurate placement during assembly.

Selection Notes

Select this component when a 1000 V reverse voltage rating is necessary for high-line applications. The 6 A current capacity suits moderate-power designs where surface-mount convenience is prioritized over through-hole robustness. Consider the 1.0 V forward voltage drop for efficiency calculations in low-voltage output stages.

Part Context

This part belongs to Vishay's SUPERECTIFIER family, which integrates standard recovery characteristics into surface-mount packages. The GBU series specifically targets applications replacing traditional through-hole bridges while maintaining similar electrical performance metrics. The M3 suffix indicates lead-free composition compliant with EU RoHS directives.

Replacement Considerations

Direct substitutes include the GBU6M-E3/51 variant, which shares identical electrical characteristics but may differ in specific environmental certification documentation. Verify pin compatibility before swapping between E3 and M3 suffixes as packaging consistency remains critical for existing footprints.
