GBU805H

Overview

The GBU805H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It utilizes silicon technology and features an inline bridge rectifier configuration housed in a GBU-4 package for through-hole mounting. The device is rated for a peak reverse voltage of 500 V and supports a continuous forward current of 8 A. Key electrical characteristics include a maximum forward voltage drop of 1.1 V and a surge current capability of 200 A. It operates within a temperature range from -55 °C to +150 °C.

Feature Summary

• High surge current capability for robust transient protection
• Low forward voltage drop for improved efficiency
• Wide operating junction temperature range

Applications

• General purpose power supply circuits
• Battery chargers
• DC-DC converters

Procurement Notes

Verify the specific manufacturer datasheet for the GBU805H to confirm exact pinout, thermal resistance values, and mechanical dimensions. Ensure the component meets required RoHS compliance standards for your target market. Cross-reference with official distributor catalogs to validate part authenticity and availability status before procurement.

Selection Notes

Select this component when a high-current 8 A bridge rectifier with a 500 V reverse voltage rating is required. Consider the GBU-4 package size constraints for PCB layout. Evaluate thermal management requirements based on the 1.1 V forward voltage drop at full load to ensure reliable operation within the specified temperature limits.
