GBU6D-M3/45

Overview

The GBU6D-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 200 V. The device utilizes glass passivation for environmental protection and is housed in a GBU (GPP Bridge Unit) package designed for through-hole mounting. Key electrical parameters include a maximum RMS input voltage of 140 V, a maximum DC blocking voltage of 200 V, and a maximum non-repetitive surge peak forward current of 175 A at 8.3 ms half-sine wave. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated die provides high reliability and resistance to moisture and mechanical stress.
• High surge current capability supports robust performance during transient load conditions.
• Designed for efficient heat dissipation through the molded epoxy case and lead frame structure.

Applications

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

Procurement Notes

Verify the specific suffix /45 against the manufacturer's latest documentation to confirm packaging configuration, as suffixes often denote tube or reel variations. Ensure compliance with RoHS directives if required by the end application. Cross-reference the Mouser number 625-GBU6D-M3/45 or DigiKey identifier for accurate sourcing from authorized distributors.

Selection Notes

Select this component when a 6 A continuous current rating and 200 V reverse voltage are required for through-hole assembly. Compare the GBU package thermal characteristics against PCB layout constraints. Verify that the 175 A surge rating exceeds the expected inrush currents of the target circuit to prevent device failure during startup.

Part Context

This part belongs to the GBU series of single-phase bridge rectifiers from Vishay. The series offers various voltage ratings and current capacities within the same standardized footprint. The GBU6D variant specifically targets applications requiring moderate current handling with a 200 V blocking capability, fitting into the broader portfolio of general-purpose power rectification solutions.

Replacement Considerations

Compatible replacements include other GBU6x-M3 variants from Vishay with matching current ratings but different voltage codes (e.g., GBU6A, GBU6B, GBU6E). External manufacturers offering equivalent GBU-style packages with 6 A and 200 V specifications may also serve as substitutes, provided pinout and thermal parameters align.
