GBU806H

Overview

The GBU806H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor, designed for through-hole mounting in the GBU-4 package. It features an average forward current of 8 A and a peak repetitive reverse voltage of 800 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and supports a maximum surge current of 200 A. Operating temperatures range from -55°C to +150°C junction temperature. The component has dimensions of 22.3 mm in length, 18.8 mm in height, and 3.56 mm in width. It carries AEC-Q101 qualification and utilizes silicon technology with a reverse leakage current of 5 µA.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High thermal stability with operation up to +150°C
• Robust surge overload capability handling 200 A peak current

Applications

• Automotive power supply circuits
• Industrial AC-to-DC conversion systems
• General-purpose bridge rectification in high-reliability environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and packaging format. Ensure the procurement channel provides traceable documentation confirming AEC-Q101 compliance status. Cross-reference the part number with the latest Taiwan Semiconductor release notes to validate manufacturing origin and RoHS status before finalizing orders.

Selection Notes

Select this component when an 800 V blocking voltage and 8 A continuous current are required in a through-hole configuration. The GBU-4 package offers a compact footprint suitable for PCB mounting where space is constrained but high current capacity is necessary. 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 covers various voltage ratings from 50 V to 1000 V while maintaining consistent mechanical dimensions and thermal characteristics. The GBU806H specifically addresses applications requiring higher voltage isolation compared to lower-rated variants within the same physical package family.

Replacement Considerations

Direct substitutes include the GBU806HD2 variant from the same manufacturer, which shares identical electrical specifications but differs in reel packaging. Verify pinout compatibility and thermal resistance parameters when considering cross-manufacturer alternatives to ensure circuit performance remains unaffected.
