GBU6G

Overview

The onsemi GBU6G is a single-phase bridge rectifier designed for through-hole mounting in the GBU-4 package. It features a peak average forward current (If) of 6 A and a maximum repetitive peak reverse voltage (Vrrm) of 400 V. The device supports a non-repetitive peak forward surge current (Ifsm) of 175 A at 60 Hz. Electrical characteristics include a maximum DC forward voltage drop (Vf) of 1 V at rated current and a maximum RMS reverse current (Ir) of 500 µA at 25 °C. The component operates within a junction temperature range of -55 °C to +150 °C, with physical dimensions of 22.3 mm in length and 18.8 mm in height.

Feature Summary

• Utilizes high-efficiency silicon planar technology for reliable rectification.
• Designed for high thermal stability with an extended operating temperature range up to 150 °C.
• Features low forward voltage drop to minimize power dissipation during operation.

Applications

• AC-to-DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and compliance status. Ensure the procurement channel provides valid traceability documentation. Confirm that the received components match the GBU-4 package specifications and pinout configuration before integration into the design.

Selection Notes

Select this component when a 6 A continuous current rating and 400 V blocking voltage are required for through-hole applications. Consider the 175 A surge capability for inrush current handling. Evaluate thermal management requirements based on the 1 V forward voltage drop at full load to ensure the junction temperature remains within the specified 150 °C limit.

Part Context

The GBU6G belongs to the GBU series of bridge rectifiers from onsemi, which are characterized by their robust plastic encapsulation and high current density. This series is engineered for general-purpose power conversion tasks, offering a balance between performance and cost-effectiveness for standard AC rectification needs in consumer and industrial electronics.

Replacement Considerations

Direct substitutes must maintain the 6 A current rating, 400 V reverse voltage, and GBU-4 package footprint. Verify compatibility with existing PCB layouts and thermal constraints. Cross-reference with other manufacturers' GBU-series equivalents to ensure identical pinout and mechanical dimensions.
