GBJ1004-G

Bridge Rectifier Overview

The GBJ1004-G is a bridge rectifier manufactured by Comchip Technology, designed for through-hole mounting in the GBJ-W package. It features a 10 A average forward rectified current rating and a maximum repetitive peak reverse voltage of 400 V. The device utilizes glass passivated chip junctions to ensure high reliability and low leakage current under reverse bias conditions. Electrical characteristics include a maximum non-repetitive peak forward surge current capability and a specified maximum RMS isolation voltage. The component operates within a standard temperature range suitable for general-purpose power supply applications.

Bridge Rectifier Feature Summary

• Glass passivated chip junction provides enhanced stability and reduced reverse leakage current compared to standard plastic-passivated alternatives.
• Molded plastic case construction meets UL flammability classification 94V-0 for improved safety in enclosed environments.
• Low forward voltage drop design contributes to higher overall conversion efficiency and reduced thermal dissipation requirements.

Bridge Rectifier Applications

• General purpose AC-to-DC rectification in printed circuit board assemblies.
• Power supply units requiring reliable half-wave or full-wave bridge configurations.
• Adapters and chargers utilizing standard GBJ footprint constraints.

Bridge Rectifier Procurement Notes

Verify the specific manufacturer source when sourcing this component, as distribution channels may list it under generic bridge rectifier categories. Confirm that the ordering suffix matches the exact electrical specifications required for your design, particularly regarding the 400 V reverse voltage rating. Ensure the package type aligns with your PCB layout requirements before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 10 A current capacity and 400 V blocking voltage are required in a compact through-hole format. Compare the thermal resistance and forward voltage drop against alternative packages like GBPC or GBU if space constraints differ. Verify that the operating temperature range covers the intended environmental conditions of the final assembly.

Bridge Rectifier Part Context

This part belongs to the GBJ series of bridge rectifiers from Comchip Technology, which offers various voltage ratings within the same physical footprint. The GBJ1004 variant specifically targets 400 V applications, distinguishing it from other members of the family such as the 50 V or 1000 V versions. This series is widely used in industrial and consumer electronics for its balance of performance and cost-effectiveness.

Bridge Rectifier Replacement Considerations

Compatible substitutes include the GBJ1004 from other manufacturers such as SECOS or ETC2, provided they match the 10 A/400 V specifications and GBJ package dimensions. Verify pinout compatibility and thermal characteristics before substituting to ensure equivalent performance in the target circuit.
