GBU4K-5400M3/51

Overview

The GBU4K-5400M3/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an average forward rectified current of 4 A and a maximum repetitive peak reverse voltage of 1000 V. The device utilizes a GBU package with screw mounting terminals, measuring 28.8 mm in length and width, with a height of 16.7 mm. It operates within a temperature range of -55 °C to +150 °C, with a non-repetitive peak surge current capacity of 150 A.

Feature Summary

• High thermal stability enabling operation at elevated junction temperatures up to 150 °C
• Robust mechanical construction designed for high-vibration environments via screw mount configuration
• Low forward voltage drop characteristics optimized for efficient power conversion

Applications

• Industrial power supply units requiring reliable AC-to-DC conversion
• General-purpose rectification in equipment subject to mechanical stress
• Battery charging circuits operating under demanding thermal conditions

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm terminal plating and packaging details. Confirm RoHS compliance status directly with the supplier as environmental declarations may vary by production batch. Ensure the requested quantity matches available factory pack sizes to avoid partial reel issues.

Selection Notes

Select this component when a 4 A continuous current rating and 1000 V blocking voltage are required in a screw-mount topology. Evaluate the 150 A surge capability against potential inrush currents in the target circuit. Compare the physical dimensions against available board space or chassis mounting points before finalizing the design.

Part Context

This part belongs to the GBU series of bridge rectifiers from Vishay, which provides various current and voltage ratings in a standardized screw-mount package. The series is commonly used in industrial applications where robust mechanical connections and high thermal performance are prioritized over surface-mount solutions.

Replacement Considerations

Direct substitutes include other 4 A, 1000 V screw-mount bridge rectifiers such as the GBPC4005 or similar Vishay variants like the GBU4K-E4/51. Verify pinout compatibility and mounting hole spacing before substitution.
