GBU4GL-6420E3/51

Overview

The GBU4GL-6420E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 3 A. The device utilizes the GBU package for through-hole mounting. Key electrical parameters include a maximum RMS diode current of 4.5 A, a non-repetitive peak forward surge current of 100 A at 8.3 ms half-sine wave, and a maximum DC blocking leakage current of 5 µA at 400 V. The component operates within a junction temperature range of -55°C to +175°C.

Feature Summary

High thermal performance with extended operating junction temperature up to 175°C
Low forward voltage drop for improved efficiency
Compliant with RoHS standards and halogen-free construction

Applications

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

Procurement Notes

Verify that the specific suffix /51 corresponds to the required tube packaging configuration, as standard variants may differ. Confirm compliance with RoHS directives and halogen-free requirements if environmental regulations apply to your assembly process. Ensure the procurement channel provides valid traceability documentation for the Vishay manufacturing origin and lot codes.

Selection Notes

Select this component when a 400 V rating and 3 A continuous current capacity are required in a through-hole GBU package. Consider the 175°C junction temperature capability for high-thermal environments where standard 150°C devices would fail. Evaluate the low forward voltage characteristics against alternative bridge rectifiers to optimize system efficiency and reduce heat dissipation requirements.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Vishay. The series is designed for general-purpose applications requiring robust performance in compact through-hole packages. The GBU4GL variant specifically offers optimized electrical characteristics compared to standard GBU models, focusing on reduced forward voltage and enhanced thermal stability for reliable operation in demanding power conversion scenarios.
