GBU8K-7001M3/45

Overview

The GBU8K-7001M3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an 8 A average forward current rating and an 800 V maximum repetitive peak reverse voltage. The device utilizes glass passivated junctions for enhanced stability and reliability under various operating conditions. It is housed in a GBU plastic package designed for through-hole mounting on printed circuit boards. Key electrical specifications include a maximum RMS input voltage of 560 V, a peak inverse voltage of 800 V, and a surge current capability of 200 A. The component operates within a temperature range from -55 °C to +150 °C.

Feature Summary

• Glass passivated junction construction ensures high reliability and stable performance across wide temperature ranges.
• High surge current capability allows the device to withstand transient overloads during power-up or fault conditions.
• Low forward voltage drop contributes to improved system efficiency and reduced thermal dissipation requirements.

Applications

• AC-to-DC conversion circuits in general-purpose power supplies
• Battery charging systems requiring robust rectification
• Inverter and converter topologies in industrial equipment

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact packaging and compliance status. Ensure that the ordering code matches the required RoHS and REACH directives for your region. Confirm lead times and availability directly with authorized distributors as supply levels fluctuate. Validate that the procurement channel is an authorized partner to guarantee component authenticity and traceability.

Selection Notes

Select this component when an 8 A current rating and 800 V blocking voltage are required for through-hole applications. Compare the GBU package dimensions against available PCB space constraints before finalizing the design. Consider the thermal management requirements based on the expected forward current and ambient operating temperatures. Verify compatibility with the intended soldering process and reflow profile specifications provided in the datasheet.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Vishay Semiconductors. The series offers various voltage ratings and current capacities to suit different power electronics needs. The M3 suffix typically indicates lead-free and halogen-free compliance, aligning with modern environmental standards. This specific variant targets applications needing reliable rectification at moderate power levels.

Replacement Considerations

Direct replacements must match the 8 A current, 800 V voltage, and GBU package footprint. Verify pinout compatibility and thermal characteristics before substitution. Consult Vishay's cross-reference tools for approved alternative part numbers within the same product family.
