KBU805G T0G

Overview

The KBU805G T0G is a single-phase bridge rectifier from the Taiwan Semiconductor KBU series, rated for a maximum repetitive peak reverse voltage of 600 V and a maximum average forward rectified current of 8 A. It features a glass passivated junction with a typical instantaneous forward voltage of 1.0 V at 4 A and 1.1 V at 8 A. The device supports a peak forward surge current of 200 A and operates within a junction temperature range of -55°C to +150°C. Packaged in a molded plastic case weighing approximately 7.2 g, it utilizes matte tin plated leads compliant with JESD22-B102 solderability standards.

Feature Summary

• Glass passivated junction construction providing high case dielectric strength
• Halogen-free molding compound meeting UL flammability classification rating 94V-0
• Compliant with RoHS Directive 2011/65/EU and WEEE 2002/96/EC standards

Applications

• Printed circuit board mounting for general-purpose rectification
• Power supply units requiring high surge current capability
• Industrial equipment operating under high temperature conditions

Procurement Notes

Verify the specific ordering suffix 'T0G' against the manufacturer's packing code documentation to confirm the inclusion of green halogen-free compound. Ensure that procurement specifications align with the required voltage ratings and thermal management requirements for the intended application environment.

Selection Notes

Select this component when a 600 V blocking voltage and 8 A continuous current are required in a compact through-hole package. Consider the thermal resistance values and derating curves for ambient temperatures exceeding 25°C. Verify compatibility with PCB layout dimensions and mounting torque limits specified in the mechanical data section.

Part Context

This part belongs to the KBU80xG family of glass passivated bridge rectifiers manufactured by Taiwan Semiconductor. The series offers various voltage ratings from 50 V to 1000 V, sharing identical mechanical footprints and electrical characteristics except for the reverse voltage parameters. The 'G' suffix indicates compliance with halogen-free material definitions.

Replacement Considerations

Direct replacements must match the 8 A current rating, 600 V reverse voltage, and KBU package outline. Verify lead spacing and terminal plating compatibility. Cross-reference with other manufacturers offering equivalent glass-passivated bridge rectifiers in the same form factor.
