KBU401G T0

Overview

The KBU401G T0 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features four internal silicon diodes arranged in a full-bridge configuration within a plastic encapsulated module. The device is rated for a repetitive peak reverse voltage of 400V and an average forward rectified current of 4A at a case temperature of 75°C. It utilizes a glass-passivated junction construction to ensure stability under harsh conditions. The component operates with a maximum non-repetitive surge current capability of 150A and maintains a low forward voltage drop, supporting efficient power conversion in various electronic circuits.

Feature Summary

• Glass-passivated junctions provide mechanical strength and immunity to most common chemical solvents.
• High thermal performance allows for reliable operation across extended temperature ranges.
• Plastic molding compound resists moisture and withstands soldering conditions required for automated assembly.

Applications

• Adapters and chargers
• Inverters
• Power supplies

Procurement Notes

Verify the specific suffix 'T0' against official datasheets to confirm tape-and-reel packaging or marking variations. Ensure the part number matches the exact electrical ratings required for the target circuit design before procurement.

Selection Notes

Select this component when a compact full-wave rectification solution is needed for currents up to 4A. Verify that the 400V reverse voltage rating exceeds the peak inverse voltage present in the application circuit to prevent breakdown.

Part Context

This component belongs to the KBU series of bridge rectifiers from Taiwan Semiconductor. The series offers various voltage and current combinations to suit different power supply requirements while maintaining a standard surface-mount compatible package footprint.

Replacement Considerations

Check for direct equivalents from other manufacturers offering identical 4A/400V specifications in similar packages. Ensure pinout compatibility and thermal characteristics match the original design constraints.
