GBJ6K

Overview

The GeneSiC Semiconductor GBJ6K is a single-phase glass passivated silicon bridge rectifier designed for through-hole mounting. It features a compact GBJ package with a maximum average forward rectified current of 6 A and a repetitive peak reverse voltage rating of 800 V. The device exhibits a maximum forward voltage drop of 1.05 V at 3 A and a maximum reverse leakage current of 5 µA at its rated DC blocking voltage. It supports a maximum forward surge current of 500 A under standard test conditions and operates within an ambient temperature range of -50 °C to +150 °C.

Feature Summary

• Single in-line DIP package providing small size and high heat-conducting performance
• Compliant with RoHS provisions and epoxy resin material meeting UL 94V-0 flammability standards
• High surge current capability suitable for resistive and capacitive loads

Applications

• General-purpose AC to DC conversion circuits
• Power supply units requiring compact bridge rectification
• Industrial equipment utilizing through-hole PCB assembly

Procurement Notes

Verify the specific part number suffix against official datasheets to confirm the exact voltage rating, as the GBJ series spans multiple voltage classes. Confirm compliance requirements such as RoHS and UL 94V-0 flammability ratings prior to integration. Ensure thermal management strategies align with the specified thermal resistance values for both heatsink and non-heatsink configurations.

Selection Notes

Select the GBJ6K when an 800 V reverse voltage rating is required alongside a 6 A continuous current capacity. Consider the GBJ package dimensions for PCB layout constraints. Derate the forward current by 20% if the application involves capacitive loads to ensure reliable operation within the specified thermal limits.

Part Context

The GBJ6K belongs to the GBJ series of single-phase bridge rectifiers manufactured by GeneSiC Semiconductor. This series includes variants with different voltage ratings, specifically ranging from 600 V to 1000 V, sharing common physical dimensions and electrical characteristics except for the reverse voltage specifications.

Replacement Considerations

Compatible substitutes include other GBJ6K components from different manufacturers that match the 800 V, 6 A specification and GBJ package footprint. Verify pinout compatibility and thermal resistance values before substitution.
