GBU4J-M3/45

Overview

The GBU4J-M3/45 is a glass passivated single-phase bridge rectifier from the Vishay GBU4 series, housed in a GBU through-hole package. It features a maximum repetitive peak reverse voltage of 600 V and supports a maximum average forward rectified output current of 4.0 A at a case temperature of 100 °C. The device withstands a peak forward surge current of 150 A and exhibits a maximum instantaneous forward voltage drop of 1.0 V at 4.0 A. Operating junction and storage temperatures range from -55 to +150 °C, with a typical thermal resistance of 22 °C/W.

Feature Summary

• Glass passivation provides mechanical strength and meets UL 94 V-0 flammability ratings for molding compound
• High surge current capability ensures robustness against transient electrical loads
• Terminals are matte tin plated and solderable per J-STD-002 standards
• Halogen-free construction compliant with RoHS directives

Applications

• AC/DC bridge full wave rectification in switching mode power supplies
• Adapter circuits for consumer electronics
• Monitor and TV internal power conversion stages
• Printer and home appliance power regulation

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 88614 and revision date. Confirm that the M3 suffix indicates halogen-free compliance and the /45 code specifies tube packaging containing twenty units. Ensure technical specifications align with the intended circuit requirements before finalizing orders.

Selection Notes

Select this component when a 600 V reverse voltage rating is required for single-phase rectification applications. The GBU package accommodates standard through-hole mounting processes. Evaluate thermal management needs based on the 22 °C/W junction-to-ambient thermal resistance characteristic under free-air conditions.

Part Context

This part belongs to the Vishay GBU4 family of glass passivated bridge rectifiers. The series includes variants with different voltage ratings ranging from 50 V to 1000 V, all sharing identical physical dimensions and current handling capabilities within the GBU footprint.

Replacement Considerations

GBU4J-E3/45 serves as a direct functional substitute within the same product line, differing only in material composition regarding halogen content.
