GBU4A-E3/45

Overview

The GBU4A-E3/45 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 4 A per diode. The device utilizes the GBU surface-mount package with four pins. Key electrical characteristics include a maximum non-repetitive peak forward surge current (Ifsm) of 150 A, a typical forward voltage drop (Vf) of 1 V at rated current, and a maximum reverse leakage current of 5 µA at 400 V. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Utilizes isoCINK+ technology for enhanced thermal performance and reliability in high-power applications.
• Designed for surface-mount assembly using the standardized GBU footprint to facilitate automated PCB placement.
• Complies with RoHS 3 directives and is free from halogenated flame retardants.

Applications

• General-purpose AC-to-DC conversion in power supply units.
• Battery charging circuits for consumer electronics.
• DC power supplies for industrial control systems.

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm compliance requirements. Confirm that the GBU package dimensions match the target PCB layout. Check for recent Product Change Notices regarding manufacturing location or material updates. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering.

Selection Notes

Select this component when a 400 V rating is required for mains-derived voltages. The 4 A current capacity suits moderate power applications. Compare Vf specifications against alternative brands to estimate conduction losses. Verify that the surface-mount GBU package fits within the mechanical constraints of the enclosure design.
