GBU406H

Overview

The GBU406H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage of 600V and an average forward rectified current of 4A. The device utilizes a GBU surface-mount package with four pins. Key electrical parameters include a maximum non-repetitive peak forward surge current of 150A, a maximum DC blocking voltage of 600V, and a maximum RMS voltage of 420V. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• High thermal efficiency through direct PCB mounting for effective heat dissipation
• Robust mechanical construction designed to withstand high surge currents
• Compliance with environmental standards including halogen-free and RoHS requirements

Applications

• General-purpose AC-to-DC power supply circuits
• Battery charging systems
• Industrial control equipment power stages

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's datasheet to confirm halogen-free status or tape-and-reel packaging variations. Ensure the supplier provides official traceability documents matching the Taiwan Semiconductor part number. Confirm that the delivered components match the specified GBU package dimensions and pin configuration before integration into production lines.

Selection Notes

Select this component when a 600V rating and 4A continuous current capacity are required in a surface-mount form factor. Compare the GBU406H against through-hole alternatives if board space constraints dictate a different footprint. Verify that the operating ambient temperature remains within the specified -55°C to +150°C junction range to ensure reliable long-term performance in the target application environment.

Part Context

This component belongs to the GBU series of bridge rectifiers from Taiwan Semiconductor Corporation. The series offers various voltage and current ratings within a standardized surface-mount package. The GBU406H specifically addresses applications requiring 600V isolation and 4A current handling in compact electronic designs.

Replacement Considerations

Cross-reference with other manufacturers offering GBU-4 packages rated at 600V and 4A. Verify pinout compatibility and physical dimensions before substitution. Ensure equivalent surge current ratings and thermal characteristics are met to maintain circuit integrity.
