GBU4A-E3/51

Overview

The GBU4A-E3/51 is a single-phase rectifier bridge manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage (Vrrm) of 50 V and an average forward current (If) of 4 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 150 A with a maximum forward voltage drop of 1 V. Designed for through-hole mounting, it utilizes the GBU package configuration with four pins. The component operates within a junction temperature range of -55°C to 150°C and exhibits a peak reverse current of 500 µA.

Applications

• General-purpose AC-to-DC power supply rectification
• Low-voltage DC power conversion circuits
• Industrial control system power inputs

Procurement Notes

Verify the specific suffix /51 against official Vishay documentation to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the required GBU through-hole package dimensions. Cross-reference the manufacturer date code and lot traceability requirements with the supplier's certificate of conformity prior to finalizing procurement orders.

Selection Notes

Select this component when a 50 V rating and 4 A continuous current capacity are sufficient for the application. The GBU package provides robust mechanical stability for through-hole assembly processes. Consider thermal management strategies given the 150°C maximum junction temperature limit. Verify that the 1 V forward voltage drop aligns with the efficiency requirements of the target circuit design.

Part Context

This rectifier belongs to the GBU4A series from Vishay, designed for general-purpose applications requiring reliable performance in compact through-hole layouts. The E3 designation indicates lead-free construction compliant with RoHS directives. The standard GBU footprint ensures compatibility with existing PCB designs utilizing this common bridge rectifier form factor.

Replacement Considerations

Direct replacements must match the 50 V, 4 A, GBU through-hole specification. Verify pinout compatibility and thermal characteristics before substitution.
