KBU807G

Overview

The KBU807G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor, designed for high-reliability applications. It features an 8A average forward current rating and supports a peak repetitive reverse voltage of 1000V. The device utilizes a KBU through-hole package with four pins, measuring 23.7mm in length and 19.3mm in height. It operates within a temperature range of -55°C to +150°C and withstands a non-repetitive peak forward surge current of 200A. Key electrical characteristics include a maximum forward voltage of 1V and a reverse current of 5μA.

Feature Summary

• Green compound construction indicated by the 'G' suffix for environmental compliance
• High case dielectric strength suitable for printed circuit board mounting
• Guaranteed high-temperature soldering capability at 260°C

Applications

• General purpose power supply circuits
• Industrial control systems requiring robust rectification
• Printed circuit board mounted AC-to-DC conversion

Procurement Notes

Verify component authenticity by checking for the specific 'G' prefix on the date code and suffix on the packing code, which denotes the green compound variant. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory adherence is critical for modern electronic assemblies. Ensure the ordering part number matches the exact voltage and current ratings required for the target application design.

Selection Notes

Select this component when a through-hole single-phase bridge rectifier with 1000V blocking capability and 8A continuous current is required. The KBU package offers mechanical stability for PCB mounting. Consider thermal management requirements given the 150°C maximum junction temperature limit. Verify that the 200A surge current rating meets the inrush specifications of the intended load circuit.

Part Context

This device belongs to the KBU8 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series covers various voltage ratings while maintaining consistent 8A current handling and KBU packaging dimensions. The KBU807G specifically addresses high-voltage applications within this lineup, providing a standardized solution for industrial and commercial power electronics designs requiring reliable silicon rectification.

Replacement Considerations

Cross-reference with other KBU807 variants from different manufacturers ensuring identical pinout and electrical parameters. Verify package compatibility before substitution.
