KBU1003G T0G

Overview

The KBU1003G T0G is a single-phase silicon bridge rectifier from the KBU100 series by Taiwan Semiconductor. It features a 10 A average forward current and a 200 V repetitive peak reverse voltage. The device utilizes a glass-passivated chip junction within a KBU through-hole package, supporting a maximum junction temperature of 150 °C. Electrical characteristics include a typical forward voltage of 1.1 V at 10 A and a reverse leakage current of 5 µA at rated voltage. The component handles a 200 A non-repetitive surge current and operates across a temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High case dielectric strength suitable for PCB mounting
• Compliant with UL recognition standards

Applications

• Switching mode power supplies (SMPS)
• Power adapters
• Lighting applications

Procurement Notes

Verify the specific ordering code against manufacturer documentation to ensure correct voltage rating and packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure storage conditions align with the specified temperature limits to maintain component integrity.

Selection Notes

Select this component for circuits requiring a 10 A current capacity and 200 V blocking voltage in a standard through-hole form factor. Evaluate thermal management requirements based on the 25 °C/W junction-to-ambient resistance. Ensure the application environment remains within the -55 °C to +150 °C operating range for optimal performance.

Part Context

This part belongs to the KBU1001G–KBU1007G series, which offers standardized 10 A bridge rectifiers with varying reverse voltage ratings from 50 V to 1000 V. All variants share identical mechanical dimensions, thermal characteristics, and package types, differing primarily in their peak reverse voltage specifications.

Replacement Considerations

Compatible substitutes include other 10 A, 200 V single-phase bridge rectifiers in the KBU package. Verify pinout compatibility and thermal resistance values when considering alternatives from different manufacturers.
