GBU803 D2G

Overview

The GBU803 D2G is a single-phase standard bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features an 8-ampere average forward rectified current rating and a maximum repetitive peak reverse voltage of 200 volts. The device utilizes the GBU surface-mount package, which provides robust mechanical stability for automated assembly processes. Key electrical characteristics include a non-repetitive peak forward surge current capacity and a low forward voltage drop to ensure efficient power conversion. The component is designed for general-purpose rectification applications in AC-to-DC power supplies.

Feature Summary

• Single-phase full-wave rectification capability
• Surface-mount GBU package for automated PCB assembly
• Halogen-free green molding compound construction

Applications

• AC-to-DC power supply circuits
• General-purpose rectification in consumer electronics
• Adapter and charger input stages

Procurement Notes

Verify the specific ordering suffix D2G to confirm halogen-free status and green compound packaging. Ensure compatibility with GBU footprint dimensions during procurement. Cross-reference manufacturer datasheets for thermal derating curves and surge current limits. Confirm authenticity through authorized distributors to avoid counterfeit components. Check lead times and minimum order quantities directly with suppliers before finalizing purchase orders.

Selection Notes

Select this component when an 8A current rating and 200V reverse voltage are required for space-constrained designs. The GBU package offers higher current density compared to through-hole alternatives. Consider thermal management requirements based on ambient temperature conditions. Evaluate forward voltage drop impacts on overall system efficiency. Ensure the selected variant matches the specific environmental and regulatory compliance needs of the target application.

Part Context

This part belongs to the GBU series of standard bridge rectifiers from Taiwan Semiconductor. The series includes various voltage ratings and current capacities within the same physical package. The GBU format is widely used in modern electronics manufacturing due to its compact size and reliability. This specific model represents a mid-range option within the family, balancing performance and cost for common industrial and consumer applications.

Replacement Considerations

Direct substitutes must match the 8A/200V specifications and GBU package outline. Verify pinout compatibility and thermal resistance values before substitution. Alternative manufacturers may offer equivalent parts with different suffixes indicating material variations. Ensure that any replacement meets the same UL and safety certification standards as the original component.
