GBU6M

Overview

The onsemi GBU6M is a single-phase bridge rectifier from the GBU6K series, designed for through-hole mounting in the GBU-4 package. It features a peak repetitive reverse voltage (Vrrm) of 800 V and supports a continuous forward current (If) of 6 A. The device withstands a peak non-repetitive forward surge current (Ifsm) of 175 A. Electrical characteristics include a maximum forward voltage drop (Vf) of 1 V at rated current and a low peak reverse leakage current (Ir) of 500 μA. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• High-voltage capability with an 800 V reverse voltage rating suitable for demanding power conversion applications.
• Robust surge handling capacity allowing it to manage high transient currents during startup or fault conditions.
• Wide thermal operating range ensuring reliable performance across extreme environmental temperatures.

Applications

• AC-DC power supply input stages
• Battery charging circuits
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to confirm exact electrical ratings and compliance status. Ensure the procurement channel provides valid traceability data. Confirm that the component meets required regulatory standards for the target market before finalizing orders.

Selection Notes

Select this component when an 800 V reverse voltage rating is required alongside a 6 A continuous current capacity. The GBU-4 through-hole package is appropriate for designs prioritizing mechanical stability and ease of assembly over compact surface-mount solutions. Evaluate thermal management requirements based on the specified power dissipation limits.

Part Context

The GBU6M belongs to the GBU6K series of bridge rectifiers manufactured by onsemi. This series is characterized by its robust construction and high reliability for general-purpose rectification tasks. The GBU6M specifically denotes the 800 V variant within this lineup, sharing common package dimensions and thermal characteristics with other members of the family.

Replacement Considerations

Cross-reference with other 800 V, 6 A bridge rectifiers in the GBU-4 package. Verify pinout compatibility and ensure equivalent surge current ratings are met by potential substitutes.
