GBU8A-M3/45

Overview

The GBU8A-M3/45 is a single-phase bridge rectifier manufactured by Vishay Semiconductors. It features an average forward rectified current of 8 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes glass passivation for the junctions, ensuring low leakage currents. It is housed in a GBU (D2PAK) package designed for through-hole mounting with solder pin termination. The component supports a maximum non-repetitive peak forward surge current of 200 A at 60 Hz. Operating temperatures range from -55 °C to +150 °C for the junction and storage conditions.

Feature Summary

• Glass passivated junctions provide stable electrical characteristics and protection against mechanical stress.

Applications

• AC-DC power supply circuits
• Battery chargers
• General purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix /45 indicates tube packaging when sourcing. Confirm RoHS compliance status via the manufacturer datasheet as manufacturing processes may evolve. Ensure the ordering part number matches the exact voltage rating required for the target circuit design before procurement.

Selection Notes

Select this component for applications requiring 8 A continuous current handling with a 400 V blocking capability. The GBU package offers robust thermal performance for through-hole PCB layouts. Verify that the 200 A surge rating meets the inrush current requirements of the specific load connected to the rectifier bridge.

Part Context

This part belongs to the Vishay GBU8 series of single-phase bridge rectifiers. The series provides various voltage ratings while maintaining consistent current handling and package dimensions. The M3 suffix typically denotes lead-free and halogen-free construction compliant with modern environmental standards.

Replacement Considerations

Direct replacements include other GBU8 series variants with identical current ratings but different voltage ratings, such as GBU8B or GBU8C, provided the circuit voltage allows. Cross-brand equivalents in the GBU package must be verified for matching pinout and thermal resistance specifications.
