GBU10G

Overview

The GBU10G is a single-phase bridge rectifier manufactured by Diotec Semiconductor, designed for general-purpose power conversion applications. It features an average forward current rating of 10 A and a repetitive peak reverse voltage of 400 V. The device utilizes a GBU-4 through-hole package with solder pin termination. Key electrical characteristics include a maximum forward voltage of 1.1 V at 10 A, a non-repetitive peak forward surge current of 220 A (at 60 Hz), and a maximum reverse leakage current of 5 µA. It operates within a junction temperature range of -50°C to +150°C.

Feature Summary

• Single-phase bridge configuration integrating four diodes in one compact unit
• High thermal stability supporting operation up to 150°C junction temperature
• Robust surge current handling capability for transient protection
• Low forward voltage drop for improved energy efficiency

Applications

• AC-to-DC power supply circuits
• General-purpose rectification in industrial electronics
• Battery charging systems
• Adapters and converters

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure correct voltage and current ratings. Confirm RoHS compliance status and packaging details directly with authorized distributors or the manufacturer before ordering. Cross-reference datasheet specifications with design requirements to validate suitability for the intended application environment.

Selection Notes

Select this component based on the required 10 A current capacity and 400 V reverse voltage rating. Ensure the PCB layout accommodates the GBU-4 package dimensions and provides adequate thermal dissipation for the case temperature. Consider the mounting torque specifications and verify that the circuit design limits surge currents within the 220 A rating.

Part Context

This component belongs to the GBU series of single-phase bridge rectifiers from Diotec Semiconductor. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 10 A current rating and standardized GBU-4 package footprint. This allows for flexible design options across different voltage requirements without changing the physical board layout.

Replacement Considerations

Compatible substitutes include other 10 A, 400 V single-phase bridge rectifiers in the GBU-4 package. Verify equivalent electrical parameters such as forward voltage, reverse leakage, and surge current ratings. Ensure mechanical compatibility regarding lead spacing and mounting hole dimensions before substitution.
