GBU804H

Overview

The GBU804H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features an 8 A average forward current rating and a 400 V maximum repetitive peak reverse voltage. The device utilizes a GBU-4 through-hole package with solder pin termination. Key electrical parameters include a 1.1 V maximum forward voltage drop, a 5 uA maximum reverse leakage current, and a 200 A non-repetitive peak forward surge current capability. It operates within a temperature range of -55 °C to +150 °C junction temperature and holds AEC-Q101 qualification.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High thermal stability supporting operation up to 150 °C
• Robust surge current handling capacity

Applications

• Automotive power supply circuits
• General-purpose AC to DC conversion
• Battery charging systems

Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm packaging details and RoHS compliance status. Ensure the selected component matches the required GBU-4 footprint dimensions and pin configuration for your PCB layout. Cross-reference the AEC-Q101 certification requirements with your system's automotive grade specifications before finalizing procurement.

Selection Notes

Select this component when an 8 A current rating and 400 V blocking voltage are required in a standard through-hole bridge configuration. The GBU-4 package offers a balance of current capacity and board space efficiency. Consider the 1.1 V forward voltage drop for thermal management calculations in high-efficiency designs requiring low conduction losses.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Taiwan Semiconductor. The series provides various voltage ratings for different applications. The 'H' suffix typically denotes specific packaging or environmental compliance variations within the product line, distinguishing it from standard GBU variants.

Replacement Considerations

Direct substitutes must match the 8 A / 400 V specification and GBU-4 package. Verify equivalent parts like GBU804 or GBU806 only if voltage/current ratings exceed requirements and pinouts are identical.
