GBU8K-LV-T

Overview

The GBU8K-LV-T is a single-phase silicon bridge rectifier from Diotec Semiconductor, housed in the GBU through-hole package. It features an average forward current of 8A and a maximum repetitive peak reverse voltage of 800V. The device supports a surge current of 180A and operates at a maximum junction temperature of 150°C. This low-variance variant is designed for high-reliability applications requiring stable performance under thermal stress.

Feature Summary

• Utilizes low-variance technology to ensure consistent electrical characteristics across production batches
• Constructed with silicon planar dielectric isolation for enhanced robustness
• Equipped with metal oxide varistor (MOV) protection against transient overvoltages

Applications

• Industrial power supply units
• Motor drive systems
• Battery chargers

Procurement Notes

Verify that the ordering suffix -T corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the low-variance designation aligns with strict tolerance requirements for the target application. Ensure compatibility with standard GBU footprint mounting constraints during integration.

Selection Notes

Select this component when high reliability and consistent performance are critical for long-term operation. The 800V rating provides adequate margin for industrial AC line voltages. Consider the 150°C operating limit for environments with elevated ambient temperatures or limited cooling options compared to standard 125°C rated alternatives.

Part Context

This part belongs to Diotec's GBU series of single-phase bridge rectifiers, which are widely used in general-purpose power conversion circuits. The GBU package offers a compact solution for medium-power applications, balancing current handling capabilities with board space efficiency in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 800V, 8A single-phase bridge rectifiers in the GBU package. Verify pinout compatibility and thermal resistance specifications before substitution. Alternative low-variance variants within the same manufacturer family may offer improved consistency.
