KBU604G T0G

Overview

The KBU604G T0G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor. It features an average forward current rating of 6 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes a glass-passivated junction for enhanced reliability and is housed in a KBU-4 through-hole package with solder pin termination. Key electrical characteristics include a typical forward voltage of 1 V, a maximum surge current capability of 175 A, and a low reverse leakage current of less than 0.1 μA. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass-passivated junction construction ensures high reliability and stable performance under varying thermal conditions.
• High case dielectric strength provides robust insulation and protection against electrical stress.
• Designed specifically for efficient mounting on printed circuit boards using a through-hole configuration.

Applications

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

Procurement Notes

Verify the specific suffix 'T0G' against official manufacturer documentation to confirm packaging details and halogen-free status. Ensure compatibility with standard KBU-4 footprints during sourcing. Cross-reference datasheet revisions to confirm compliance with current RoHS directives and WEEE regulations before finalizing procurement orders.

Selection Notes

Select this component when a 6 A current rating and 400 V blocking voltage are required in a compact through-hole format. Consider the 175 A surge capability for applications with high inrush currents. Verify that the operating environment stays within the specified -55°C to +150°C range to maintain optimal forward voltage and leakage current performance.

Part Context

This part belongs to the KBU series of bridge rectifiers from Taiwan Semiconductor, designed for general-purpose applications. The KBU604G variant specifically offers a 400 V reverse voltage rating, distinguishing it from other ratings in the family such as the 200 V or 600 V options. The 'G' suffix typically indicates a green, halogen-free compound compliant with environmental standards.

Replacement Considerations

Direct replacements must match the 6 A current, 400 V voltage, and KBU-4 package dimensions. Verify pinout compatibility and thermal characteristics. Check if alternative manufacturers offer equivalent glass-passivated junctions with similar surge current ratings.
