GBU806G

Overview

The GBU806G is a single-phase bridge rectifier manufactured by SMC Diode Solutions. It features a maximum repetitive peak reverse voltage of 600 V and an average rectified output current of 8 A. The device utilizes standard technology and is housed in a GBU (4-ESIP) through-hole package. Key electrical characteristics include a forward voltage of 1.1 V at 8 A and a reverse leakage current of 5 µA at 600 V. It operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Provides reliable AC-to-DC conversion for single-phase applications
• Designed for robust performance in high-temperature environments up to 150°C
• Utilizes a compact GBU surface-mount compatible through-hole package

Applications

• General-purpose power supply circuits
• Battery charging systems
• DC power adapters

Procurement Notes

Verify the specific suffix 'G' against official manufacturer documentation, as standard listings typically reference 'GBU806'. Confirm RoHS3 compliance status directly with the supplier. Ensure the ordering part number matches the exact pinout and packaging requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when a 600 V rating and 8 A continuous current capacity are required. The GBU package offers a balance of current handling and board space efficiency compared to larger axial leads. Consider thermal management strategies given the 1.1 V forward voltage drop at full load to maintain junction temperatures within safe operating limits.

Part Context

The GBU806 belongs to SMC Diode Solutions' GBU series of single-phase bridge rectifiers. This family typically includes variants with different voltage ratings (e.g., 200V, 400V, 800V, 1000V) while maintaining the same 8 A current rating and physical footprint. The GBU806 specifically targets applications requiring 600 V isolation.

Replacement Considerations

Direct replacements from other manufacturers must match the 8 A current, 600 V voltage, and GBU/4-ESIP package dimensions. Verify pin configuration compatibility. Equivalent parts may include generic GBU806 components from other diode manufacturers, provided they meet the same electrical specifications.
