GBU8KL-5301M3/51

Overview

The GBU8KL-5301M3/51 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an 8 A average forward rectified current rating and an 800 V maximum repetitive peak reverse voltage. The device utilizes glass passivated junctions for enhanced stability and is housed in a GBU surface-mount package with solder pin terminations. Electrical characteristics include a maximum forward voltage of 1.1 V at 8 A, a surge current capability of 200 A, and a low reverse leakage current of 5 µA. The component operates within a temperature range of -55 °C to +150 °C junction temperature.

Feature Summary

• Glass passivated junction construction provides mechanical strength and stability against thermal cycling.
• Surface-mount GBU package design facilitates automated assembly and compact PCB layout.
• High surge current handling capability supports robust performance during transient load conditions.

Applications

• General-purpose AC-to-DC power supply circuits
• Battery charging systems requiring high reliability
• Industrial control equipment power stages

Procurement Notes

Verify the specific suffix configuration against official Vishay documentation to ensure correct electrical ratings and packaging details. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and traceability. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity issues before reflow soldering processes.

Selection Notes

Select this component when a surface-mount bridge rectifier with 8 A continuous current and 800 V blocking voltage is required. The GBU package offers a balance between current capacity and board space efficiency compared to through-hole alternatives. Consider the 1.1 V forward voltage drop for thermal management calculations in high-efficiency designs. Verify that the operating environment remains within the specified -55 °C to +150 °C junction temperature range for optimal longevity.

Part Context

This part belongs to the Vishay GBU series of single-phase bridge rectifiers, designed for surface-mount applications. The series provides various voltage ratings from 50 V to 1000 V while maintaining consistent 8 A current capabilities. The GBU8KL variant specifically targets high-voltage requirements within this current class, offering a standardized footprint compatible with existing GBU-series layouts.

Replacement Considerations

Direct substitutes must match the 8 A current, 800 V voltage, and GBU package dimensions. Verify equivalent forward voltage and reverse leakage specifications to ensure circuit compatibility. Check for identical mounting hole placements and terminal configurations to avoid PCB redesign requirements.
