GBU8K-T

Overview

The GBU8K-T is a glass-passivated single-phase bridge rectifier manufactured by Diotec Semiconductor. It features an 800 V maximum repetitive peak reverse voltage and an average forward rectified current of 8.0 A at 45°C ambient temperature. The device utilizes a molded plastic case with Underwriters Laboratory Flammability Classification 94V-O. Electrical characteristics include a maximum RMS input voltage of 560 V, a maximum DC blocking voltage of 800 V, and a peak forward surge current rating of 200 A for half-sine waves under specified conditions.

Feature Summary

• Glass passivation provides stable electrical performance and protects against mechanical stress.
• Molded plastic construction ensures reliable low-cost assembly on printed circuit boards.
• High thermal stability supports soldering at elevated temperatures without damage.

Applications

• AC to DC power supply circuits
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific ordering suffix to confirm tape-and-reel packaging versus bulk quantities. Confirm RoHS compliance status and REACH SVHC declarations directly from the manufacturer's latest documentation before procurement. Ensure the component matches the required flammability classification for your assembly process.

Selection Notes

Select this component when an 8 A current rating and 800 V reverse voltage are required in a standard bridge configuration. Verify that the PCB layout accommodates the GBU package dimensions and lead spacing. Consider derating the forward current if the ambient operating temperature exceeds 45°C or if capacitive loads are present.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers produced by Diotec Semiconductor. The series offers various voltage ratings ranging from 50 V to 800 V while maintaining a consistent 8.0 A current capacity. The GBU8K-T specifically denotes the 800 V variant within this standardized product line.

Replacement Considerations

Compatible substitutes include the GBU8K from other manufacturers such as Panjit, provided the pinout, package dimensions, and electrical ratings match exactly. Verify that alternative sources also offer glass passivation and equivalent surge current capabilities.
