GBU4M-G

Overview

The GBU4M-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the GBU-4 package. It features a silicon construction with a maximum average forward rectified current of 4 A and a peak repetitive reverse voltage rating of 400 V. The device exhibits a maximum forward voltage drop of 1.1 V at rated current and supports a maximum surge current of 150 A. Operating temperatures range from -55°C to +150°C junction temperature, with a typical reverse leakage current of 10 µA.

Feature Summary

• Single-phase bridge rectification topology
• Through-hole solder pin termination
• High thermal stability up to 150°C

Applications

• General purpose power supply circuits
• AC to DC conversion modules
• Battery charging systems

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure accuracy, as suffixes may indicate variations in packaging or testing criteria. Confirm RoHS compliance status directly from the datasheet before integration into regulated assemblies.

Selection Notes

Select this component when a 4 A continuous current rating and 400 V blocking voltage are required in a standard GBU-4 footprint. Ensure the application's thermal management can handle the dissipation associated with the specified forward voltage drop at the expected load conditions.

Part Context

This component belongs to the GBU series of bridge rectifiers from Comchip Technology, which offers various current and voltage ratings within the same mechanical housing. The GBU4M-G specifically targets applications requiring moderate current handling capabilities with robust reverse voltage protection in a compact through-hole form factor.

Replacement Considerations

Compatible substitutes include other 4 A, 400 V single-phase bridge rectifiers in the GBU-4 package, such as those from Vishay or Littelfuse, provided pinout compatibility and electrical parameters meet or exceed the original specifications.
