GBU8D-E3/51

Overview

The GBU8D-E3/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features glass passivation for environmental protection and is designed for through-hole mounting in the GBU package. The device supports a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 8 A. It exhibits a maximum forward voltage drop of 1 V at rated current and can withstand a non-repetitive peak surge current of 200 A. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated die provides improved stability and reliability under harsh environmental conditions.
• Utilizes plastic material classified as UL flammability rating 94V-0.
• Molded epoxy resins are halogen-free, ensuring compliance with specific environmental standards.

Applications

• General purpose rectification in AC-to-DC power supply circuits.
• Battery charging systems requiring robust diode performance.
• Industrial control equipment utilizing low-voltage DC power distribution.

Procurement Notes

Verify the manufacturer part number against official Vishay documentation to ensure authenticity. Confirm that the E3 suffix indicates lead-free composition and RoHS compliance. Check the /51 suffix specifically for tray packaging configuration if required by assembly processes. Validate the date code and lot traceability upon receipt to ensure component integrity and storage history alignment with specifications.

Selection Notes

Select this component when a through-hole single-phase bridge rectifier is required for 200 V applications. Ensure the circuit design accommodates the 8 A continuous current rating and the thermal management needs associated with the GBU package. Verify that the operating environment remains within the specified -55 °C to +150 °C temperature range. Consider the 200 A surge capability for inrush current protection requirements in the target application.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Vishay. The series is characterized by high current density and low forward voltage drop. The GBU8D variant specifically denotes an 8 A, 200 V rating. The E3 designation signifies that the product is compliant with RoHS directives and is free from halogenated flame retardants, aligning with modern electronic manufacturing environmental standards.

Replacement Considerations

The GBU8D-M3/51 is a confirmed equivalent part number within the same product line. Both variants share identical electrical ratings and mechanical dimensions. The M3 suffix also indicates lead-free and RoHS compliance. Verify pinout compatibility and thermal characteristics before substitution in existing designs.
