KBU802G T0

Overview

The KBU802G T0 is a single-phase bridge rectifier from the Taiwan Semiconductor KBU8 series, rated for an average forward current of 8.0 A and a maximum repetitive peak reverse voltage of 200 V. It utilizes a glass-passivated junction within a molded plastic KBU case, featuring pure tin-plated leads for through-hole mounting. The device supports a peak non-repetitive forward surge current of 175 A and operates across a temperature range of -55°C to +150°C. With a typical reverse current below 0.1 µA and a peak forward voltage of 1 V, it offers high dielectric strength and compliance with UL standards.

Feature Summary

• Glass-passivated junction provides high reliability and stability under varying thermal conditions.
• Molded plastic case meets UL flammability classification 94V-0 for enhanced safety.
• Green compound variant ensures halogen-free composition in accordance with IEC 61249-2-21.

Applications

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

Procurement Notes

Verify the specific suffix 'T0' against manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure the 'G' prefix or packing code indicates the halogen-free green compound version if environmental compliance is mandatory. Cross-reference the date code and lot number to confirm production batch details prior to ordering.

Selection Notes

Select this component when an 8 A continuous current rating and 200 V blocking voltage are required in a through-hole KBU package. 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 and that PCB layout accommodates the KBU mechanical dimensions.

Part Context

This part belongs to the KBU8 series of single-phase bridge rectifiers from Taiwan Semiconductor. The series covers various voltage ratings from 20 V to 1000 V while maintaining a consistent 8.0 A current capacity and KBU form factor. The KBU802G specifically denotes the 200 V variant within this standardized lineup designed for general-purpose rectification.

Replacement Considerations

Compatible alternatives include the Vishay KBPC8005W-50L (8 A, 50 V) or other KBU-series rectifiers from different manufacturers with matching 8 A and 200 V ratings. Ensure substitute parts maintain the same KBU footprint and lead configuration for direct replacement without PCB modification.
