GBU8J

Overview

The onsemi GBU8J is a single-phase silicon bridge rectifier designed for general-purpose power supply applications. It features a peak repetitive reverse voltage (Vrrm) of 600 V and an average forward rectified current (If) of 8 A at 100°C. The device supports a peak non-repetitive forward surge current (Ifsm) of 200 A under specified conditions. Key electrical parameters include a maximum peak forward voltage (Vf) of 1 V and a peak reverse current (Ir) of 5 μA. The component operates within a junction temperature range of -55°C to +150°C and utilizes a GBU through-hole package with dimensions of 22.3 mm in length, 18.8 mm in width, and 3.56 mm in height.

Feature Summary

• Glass passivated junction technology provides reliable operation and protection against corrosion.

Applications

• General purpose rectification in AC-DC power supplies
• Battery charging circuits
• Inverter freewheeling diodes

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct voltage rating and packaging configuration. Confirm that the component meets required safety certifications such as UL or equivalent standards for the intended application region. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a 600 V reverse voltage rating is required for single-phase rectification. Ensure the thermal management design accommodates the 8 A continuous current capability and the 150°C maximum junction temperature limit. Verify that the GBU through-hole footprint matches the PCB layout constraints and mechanical mounting requirements of the target system.

Part Context

The GBU8J belongs to the GBU series of single-phase bridge rectifiers manufactured by onsemi. This series is characterized by its glass passivated chip junctions and high surge current capability. The GBU package offers a compact solution for board-mounted applications, providing a balance between current handling capacity and physical size for standard power conversion designs.

Replacement Considerations

Compatible substitutes include other 600 V, 8 A single-phase bridge rectifiers in the GBU package, such as the GBU8K (800 V) or GBU8M (1000 V), provided the voltage margin allows. Ensure any replacement maintains identical pinout, thermal characteristics, and package dimensions to fit existing footprints without redesign.
