GBU407

Overview

The Taiwan Semiconductor GBU407 is a single-phase bridge rectifier designed for through-hole mounting in the GBU package. It features a peak repetitive reverse voltage (Vrrm) of 1000 V and an average forward rectified current (If) of 4 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 280 A. Electrical characteristics include a maximum forward voltage (Vf) of 1.1 V and a peak reverse current (Ir) of 500 μA. It operates within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

• High voltage capability with 1000 V reverse blocking rating
• Robust surge handling with 280 A peak non-repetitive forward current support
• Extended thermal operation up to 150°C junction temperature
• Automotive grade qualification compliant with AEC-Q101 standards

Applications

• AC-DC power supply circuits requiring high voltage isolation
• Industrial motor drive rectification stages
• Automotive electronics systems meeting AEC-Q101 requirements

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package type is GBU and pin configuration matches standard single-phase bridge layouts. Ensure ordering suffixes align with specific packaging or tape-and-reel requirements if applicable, as these do not alter electrical function but affect logistics.

Selection Notes

Select this component when designing circuits requiring 1000 V reverse voltage blocking and 4 A continuous current in a through-hole GBU footprint. Consider the 1.1 V forward voltage drop for thermal management calculations. Verify that the 280 A surge rating meets transient protection needs in the target application environment.

Part Context

This part belongs to the GBU4 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent 4 A current capacity and GBU package dimensions. It serves as a standard solution for general-purpose rectification in industrial and automotive applications where reliability and high voltage tolerance are critical.

Replacement Considerations

Direct substitutes must match 1000 V Vrrm, 4 A If, and GBU package. Check equivalent parts from other manufacturers for identical electrical parameters and pinout compatibility. Verify AEC-Q101 qualification if automotive usage is required.
