GBU4G-E3/51

Overview

The GBU4G-E3/51 is a single-phase rectifier bridge manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 400V and an average forward rectified current of 4A. The device utilizes the GBU through-hole package with four pins. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 150A, a peak forward voltage of 1V, and a peak reverse current of 5μA. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Single-phase rectification configuration
• Through-hole mounting for mechanical stability
• High thermal performance up to 150°C

Applications

• AC to DC power supply conversion
• Bridge rectifier circuits in general electronics
• Power adapter implementations

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm compliance status and packaging details. Ensure the component matches the required voltage and current ratings for the target circuit design before procurement.

Selection Notes

Select this component when a 400V rating and 4A continuous current are required in a compact through-hole form factor. Consider the thermal management requirements associated with the GBU package dimensions and operating temperature limits.

Part Context

This part belongs to the GBU4 series of single-phase rectifier bridges from Vishay. It shares the standard GBU footprint with other variants in the series that differ primarily in their voltage ratings, such as the GBU4B or GBU4M.

Replacement Considerations

Cross-reference with other GBU4 series parts like GBU4B-E3/51 or GBU4M-E3/51 if voltage ratings differ. Verify pinout compatibility and thermal characteristics when substituting.
