GBU6G-E3/51

Overview

The GBU6G-E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage (Vrrm) of 400 V and an average forward rectified current (Io) of 6 A. The device utilizes a glass-passivated junction for enhanced stability and is housed in a GBU through-hole package with four pins. Key electrical parameters include a maximum non-repetitive peak forward surge current (Ifsm) of 150 A, a peak forward voltage (Vf) of 1 V at 6 A, and a maximum reverse leakage current (Ir) of 5 µA at 400 V. The operating temperature range spans from -55°C to +150°C.

Feature Summary

• Glass-passivated junction construction ensures high reliability and stable performance under varying thermal conditions.
• High surge current capability allows the component to withstand transient overloads during startup or fault conditions.
• Through-hole GBU package design facilitates robust mechanical mounting and efficient heat dissipation for power applications.

Applications

• AC-DC power supply circuits requiring 400 V isolation
• Battery chargers and adapters
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix E3/51 against the manufacturer's latest datasheet to confirm compliance with RoHS directives and packaging specifications. Ensure that the procurement channel provides authentic Vishay components to avoid counterfeit risks. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times before finalizing orders.

Selection Notes

Select this component when a 6 A continuous current rating and 400 V reverse voltage are required in a through-hole configuration. Compare the 1 V forward voltage drop against system efficiency requirements. Consider the GBU package dimensions for PCB layout constraints. Verify that the 150 A surge rating exceeds the expected inrush currents of the target application circuit.

Part Context

This part belongs to the Vishay GBU series of single-phase bridge rectifiers, designed for general-purpose power conversion. The GBU series is widely used in various electronic devices due to its balance of current handling capacity and compact through-hole packaging. The GBU6G variant specifically targets applications needing 400 V blocking capability within the 6 A current class.

Replacement Considerations

Check for direct substitutes such as GBU6J-E3/51 if higher voltage ratings are acceptable. Verify pinout compatibility and thermal characteristics before replacing with other manufacturers' GBU-style bridges. Ensure any alternative meets the same 6 A and 400 V specifications.
