GBU6K-T

Overview

The GBU6K-T is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for general-purpose power supply applications. It features a peak repetitive reverse voltage of 1000 V and an average forward rectified current of 6 A. The device utilizes glass passivated chip junctions to ensure high reliability and long-term stability under demanding conditions. It is housed in the GBU-4 through-hole package, which provides robust mechanical strength and efficient heat dissipation capabilities. The component supports a maximum surge current of 200 A and operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Glass passivated chip junctions provide enhanced reliability and protection against corrosion.
• High surge current capability ensures resilience during transient load events.
• Plastic package meets Underwriters Laboratory flammability classification 94V-0.
• Ideal for printed circuit board mounting with guaranteed high-temperature soldering performance.

Applications

• General purpose rectification in AC/DC power supplies
• Battery chargers and adapters
• Industrial control systems requiring robust diode bridges

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches Diotec Semiconductor's official documentation. Ensure the order quantity aligns with standard reel sizes if automated placement is required. Cross-reference the datasheet for exact thermal resistance values relevant to your PCB layout.

Selection Notes

Select this component when a 6 A current rating and 1000 V reverse voltage are required in a through-hole configuration. Compare thermal performance against surface-mount alternatives if space constraints exist. Verify that the operating environment temperature does not exceed the specified junction limits without adequate heatsinking. Check compatibility with existing PCB footprints for the GBU-4 package.

Part Context

The GBU series represents Diotec Semiconductor's line of high-current bridge rectifiers. The GBU6K-T belongs to the 6 A category within this family, offering a balance between current handling capacity and physical size. This series is widely used in consumer electronics and industrial equipment where reliable AC-to-DC conversion is essential.

Replacement Considerations

Direct substitutes include other 6 A, 1000 V bridge rectifiers in the GBU-4 package from manufacturers such as Littelfuse or Vishay. Ensure equivalent forward voltage drop and reverse leakage characteristics. Verify pinout compatibility and mechanical dimensions before substitution.
