GBU6K-M3/45

Overview

The GBU6K-M3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an average forward rectified current of 6 A and a maximum repetitive peak reverse voltage of 600 V. The device utilizes glass passivation for junction protection and is housed in a GBU (D2PAK) package designed for through-hole mounting. Key electrical characteristics include a maximum RMS diode voltage of 420 V, a peak forward surge current capability of 175 A, and a maximum DC blocking voltage of 560 V. The component operates within a temperature range from -55 °C to +150 °C.

Feature Summary

• Glass passivated junctions provide robust environmental protection and long-term reliability under varying thermal conditions.
• High surge current capability allows the device to withstand transient overloads during power-up or fault conditions.
• Designed for high-reliability applications with low leakage current characteristics typical of silicon bridge rectifiers.

Applications

• AC-DC power supply circuits requiring 600 V isolation
• General-purpose rectification in industrial equipment
• Battery charging systems

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm compliance status and packaging details. Ensure that the ordering information matches the exact electrical ratings required for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and authenticity before finalizing procurement plans.

Selection Notes

Select this component when a 6 A current rating and 600 V reverse voltage are required in a through-hole GBU package. Compare the forward voltage drop and leakage current specifications against alternative bridge rectifiers to ensure compatibility with thermal management constraints. Verify that the operating temperature range meets the environmental requirements of the intended application.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Vishay. The series offers various current and voltage combinations in a standardized surface-mount compatible footprint adapted for through-hole assembly. The GBU6K variant specifically addresses mid-power rectification needs with a balance of current handling and voltage blocking capabilities.

Replacement Considerations

Check for direct substitutes such as the GBU6K-E3/45 variant which may differ only in compliance marking. Verify pinout compatibility and thermal resistance values when considering alternatives from other manufacturers to ensure seamless integration into existing PCB layouts.
