GBU8A-E3/45

Overview

The GBU8A-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes glass passivated junction technology and is housed in a GBU surface-mount package. The device features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 8 A. Key electrical parameters include a maximum RMS diode current of 12 A, a peak non-repetitive surge current of 200 A at 60 Hz, and a maximum DC blocking voltage of 50 V. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junctions provide robust protection against voltage transients.
• Designed for high reliability with low leakage currents.
• Utilizes plastic material rated UL Flammability Rating 94V-0.

Applications

• General purpose rectification in AC-to-DC power supplies.
• Battery charging circuits.
• Low voltage DC power conversion systems.

Procurement Notes

Verify the specific suffix configuration against official Vishay documentation to ensure compatibility with required RoHS standards and packaging types. Confirm that the GBU package dimensions align with the target PCB footprint before integration into production designs.

Selection Notes

Select this component when a surface-mount solution is required for 8 A applications with a 50 V reverse voltage rating. Ensure the design accounts for thermal dissipation limits inherent to the GBU package geometry under continuous load conditions.

Part Context

This part belongs to the GBU8 series of single-phase bridge rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent current handling capabilities and package form factors, facilitating standardized design approaches across different power supply voltage requirements.

Replacement Considerations

Direct replacements must match the 8 A current rating, 50 V reverse voltage, and GBU surface-mount package. Verify pinout compatibility and thermal characteristics to ensure seamless substitution without redesigning the host circuit board.
