KBU1007G

Overview

The KBU1007G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 10 A. The device utilizes the KBU through-hole package with four pins. Key electrical parameters include a maximum non-repetitive peak forward surge current of 200 A, a peak forward voltage of 1.1 V at 10 A, and a peak reverse current of 5 µA at 1000 V. The operating junction temperature range spans from -55°C to +150°C.

Feature Summary

• High efficiency design with low forward voltage drop
• Glass passivated chip for improved stability
• Isolated case construction for mounting flexibility

Applications

• AC-DC power supply circuits
• Battery chargers
• Inverter circuits

Procurement Notes

Verify component authenticity against official Taiwan Semiconductor documentation. Confirm that the specific part number matches the required 1000 V rating and KBU package dimensions. Ensure compliance with relevant environmental standards such as RoHS and REACH before integration into final assemblies.

Selection Notes

Select this component when a 10 A continuous current rating and 1000 V blocking capability are required in a through-hole configuration. Compare thermal resistance values against the application's heat dissipation requirements. Verify that the 200 A surge current rating exceeds the expected inrush currents in the target circuit design.

Part Context

This component belongs to the KBU series of bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining a consistent 10 A current capacity and KBU package form factor. It serves as a standard solution for general-purpose rectification in industrial and consumer electronics applications requiring robust performance.

Replacement Considerations

Compatible substitutes include KBU1006G and KBU1008G from the same manufacturer, which share identical current and package specifications but differ in reverse voltage ratings. Cross-manufacturer replacements must match the 10 A current, 1000 V voltage, and KBU footprint.
