GBU4D-M3/51

Overview

The GBU4D-M3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 4A and a repetitive peak reverse voltage of 200V. The device utilizes a Glass Passivated Chip configuration for enhanced reliability. It is housed in a GBU (GBL-1) package, designed for surface-mount applications. The component supports a maximum operating junction temperature of 150°C.

Feature Summary

• Glass passivated chip technology ensures stable electrical characteristics and long-term reliability under various operating conditions.

Applications

• General purpose full-wave rectification in AC to DC power supply circuits
• Battery charging systems requiring moderate current handling
• Industrial control equipment power stages

Procurement Notes

Verify the specific suffix /51 against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure that the glass passivated construction aligns with the thermal requirements of the target application environment. Cross-reference the GBU package dimensions with the PCB layout guidelines provided in the datasheet to guarantee proper solder joint integrity during assembly.

Selection Notes

Select this component when a 4A current rating and 200V reverse voltage capability are required for surface-mount designs. The GBU package offers a balance between current capacity and board space efficiency compared to larger through-hole alternatives. Consider the thermal dissipation characteristics of the GBL-1 footprint if high ambient temperatures are present in the system design.

Part Context

This part belongs to the GBU series of bridge rectifiers from Vishay, which are characterized by their inline mounting style and robust construction. The M3 suffix typically indicates lead-free compliance and halogen-free materials, adhering to modern environmental standards for electronic components used in global manufacturing supply chains.

Replacement Considerations

Direct replacements must match the 4A current rating, 200V reverse voltage, and GBU package outline. Verify that alternative manufacturers offer equivalent glass passivated chip technology to maintain similar reliability profiles in critical power conversion applications.
