GBU805

Overview

The GBU805 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features an 8A average forward rectified current rating and a maximum repetitive peak reverse voltage of 600V. The device utilizes glass passivation for the junction, ensuring high reliability and stability under various operating conditions. It is designed for through-hole mounting in the GBU-4 package, which provides high case dielectric strength. The component supports a wide operating temperature range from -55°C to +150°C junction temperature. Key electrical characteristics include a low typical reverse leakage current of less than 0.1µA and a high surge current capability, making it suitable for general-purpose power supply applications.

Feature Summary

• Glass passivated junctions provide stable performance and high reliability
• High case dielectric strength ensures robust insulation properties
• Low typical reverse leakage current minimizes power loss
• High surge current capability protects against transient overloads

Applications

• General purpose AC to DC power conversion circuits
• Printed circuit board mounted power supplies
• Battery charging systems requiring high surge tolerance

Procurement Notes

Verify the specific suffix (e.g., K) when ordering, as it may indicate packaging or compliance variations. Confirm RoHS status and halogen-free requirements with the manufacturer's latest documentation before finalizing procurement plans. Ensure compatibility with existing PCB footprints and thermal management strategies during the sourcing phase.

Selection Notes

Select this component for applications requiring an 8A current rating with 600V blocking voltage in a through-hole configuration. Consider the GBU-4 package dimensions for board space constraints. Evaluate the thermal dissipation requirements based on the ambient temperature and load conditions to ensure operation within the specified junction temperature limits.

Part Context

The GBU805 belongs to the GBU series of single-phase bridge rectifiers from Taiwan Semiconductor. This series covers voltage ratings from 50V to 1000V while maintaining a consistent 8A current rating. The GBU series is characterized by its molded plastic body, pure tin-plated terminals, and UL recognition, offering a standardized solution for various industrial and consumer electronics power stages.

Replacement Considerations

Direct pin-compatible replacements must match the 8A current rating and 600V reverse voltage specifications. Verify that alternative components offer similar surge current capabilities and operate within the same temperature range. Check for equivalent package dimensions to ensure mechanical fit without modifying the PCB layout.
