GBU6D

Overview

The onsemi GBU6D is a single-phase rectifier bridge from the GBU6K series, designed for general-purpose power conversion applications. It features a peak repetitive reverse voltage (Vrrm) of 800 V and an average forward rectified current (If) of 6 A. The device supports a peak non-repetitive forward surge current (Ifsm) of 175 A. Electrical characteristics include a maximum peak forward voltage (Vf) of 1 V and a peak reverse leakage current (Ir) of 500 μA. It operates within a temperature range of -55°C to +150°C. The component utilizes a GBU surface-mount package with four pins.

Feature Summary

• High thermal stability enabling operation up to 150°C junction temperature
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved efficiency in power circuits

Applications

• General-purpose AC-DC power supply rectification
• Battery charging circuit input stages
• Industrial power supply modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure the component matches the required voltage and current ratings for the target design. Cross-reference the part number with authorized distributors to confirm authenticity and traceability before procurement.

Selection Notes

Select this component when a 800 V reverse voltage rating and 6 A continuous current are required in a compact surface-mount form factor. Consider the GBU6K series for its balance of performance and size. Evaluate thermal management requirements given the 150°C operating limit and ensure the PCB layout supports adequate heat dissipation for the intended duty cycle.

Part Context

The GBU6D belongs to the GBU6K series of single-phase rectifier bridges manufactured by onsemi. This series is characterized by high reliability and low forward voltage drop. The GBU package provides a robust mechanical structure suitable for automated assembly processes in consumer and industrial electronics manufacturing lines.

Replacement Considerations

Direct substitutes must match the 800 V Vrrm, 6 A If, and GBU package footprint. Verify pinout compatibility and thermal resistance values. Consult the manufacturer's cross-reference guide for approved equivalent parts that meet identical electrical and mechanical specifications.
