KBU407G

Overview

The KBU407G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak average forward current of 4A and a maximum repetitive peak reverse voltage of 700V. The device utilizes glass passivation for the junctions and is housed in a KBU package designed for through-hole mounting. It has four pins and operates within a temperature range of -55°C to +150°C. The typical peak forward voltage is 1.1V, with a non-repetitive peak forward surge current rating of 150A.

Feature Summary

Glass passivated junctions provide high reliability and resistance to environmental variations.
High thermal performance supports operation up to +150°C junction temperature.
Robust surge current capability ensures protection against transient overloads.

Applications

AC-DC power supply circuits
Battery chargers
General-purpose rectification

Procurement Notes

Verify the manufacturer part number KBU407G specifically against official Taiwan Semiconductor documentation to confirm the 700V rating. Ensure the KBU through-hole package matches the target PCB footprint. Request the latest datasheet to validate electrical characteristics and mechanical dimensions before finalizing procurement specifications.

Selection Notes

Select this component when a 4A continuous current and 700V blocking voltage are required in a through-hole configuration. Compare the KBU package size against available board space. Consider the 150A surge rating for applications with significant inrush currents. Verify that the operating temperature range meets the system's thermal requirements.

Part Context

This component belongs to the KBU series of bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. The KBU407G specifically provides the 700V option within this lineup, suitable for standard mains voltage rectification applications.

Replacement Considerations

Check for direct substitutes with identical 4A/700V ratings and KBU package compatibility. Verify pinout alignment and thermal characteristics. Ensure any replacement maintains or exceeds the surge current and temperature specifications.
