GBU1005H

Overview

The GBU1005H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage of 50 V and an average forward rectified current of 15 A per leg. The device utilizes a GBU-4 through-hole package with solder pin termination. Key electrical characteristics include a maximum non-repetitive peak surge current of 300 A at 60 Hz, a typical forward voltage drop of 1.1 V at 15 A, and a maximum reverse leakage current of 5 µA at 50 V. The junction temperature range extends from -55°C to +150°C, and the component holds AEC-Q101 qualification for automotive applications.

Feature Summary

• High current capacity with 15 A average forward rectified current rating
• Automotive grade reliability certified under AEC-Q101 standards
• Robust surge handling capability supporting up to 300 A non-repetitive peak surge current
• Wide operating junction temperature range suitable for demanding thermal environments

Applications

• Automotive power supply circuits requiring high reliability
• General purpose AC to DC conversion in industrial equipment
• Battery charging systems for electric vehicles and auxiliary power units

Procurement Notes

Verify the specific suffix H against the manufacturer's latest datasheet to confirm package marking and internal die specifications. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure ordering quantities align with standard tube packaging configurations provided by Taiwan Semiconductor Corporation.

Selection Notes

Select this component when a 50 V blocking voltage and 15 A continuous current are required in a through-hole configuration. Compare forward voltage drop and thermal resistance values against alternative GBU series devices. Verify that the GBU-4 footprint matches the target PCB layout constraints and mounting requirements.

Part Context

This part belongs to the GBU series of bridge rectifiers from Taiwan Semiconductor Corporation. The series offers various voltage ratings and current capacities within the same GBU-4 package form factor. The GBU1005H specifically addresses low-voltage, high-current applications where compact through-hole mounting is preferred over surface mount alternatives.

Replacement Considerations

Cross-reference with other GBU10xxH variants from Taiwan Semiconductor for different voltage ratings. Check equivalent offerings from manufacturers such as Littelfuse or Vishay in the GBU package style. Ensure replacement parts maintain identical current ratings, thermal characteristics, and automotive qualification status.
