GBU1004-G

Overview

The Comchip Technology GBU1004-G is a glass passivated general purpose bridge rectifier designed for high reliability in power conversion applications. It features a robust GBU molded plastic case with an epoxy compound rated UL 94-V0 for flame retardancy. The device supports a continuous forward current of 10 Amperes and offers a maximum repetitive peak reverse voltage of 400 Volts. It exhibits a high surge overload rating of 220 Amperes, ensuring resilience against transient electrical stresses. The component operates within a junction temperature range of -55°C to +150°C and utilizes a standard pin configuration suitable for printed circuit board mounting.

Feature Summary

• Glass passivated chip junction provides excellent stability and low leakage current characteristics.
• High surge current capability ensures protection against transient overloads during operation.
• Molded plastic case meets UL 94-V0 flammability ratings for enhanced safety compliance.

Applications

• General purpose AC-DC power supply circuits
• Battery charging systems requiring high surge tolerance

Procurement Notes

Verify the specific manufacturer source when sourcing this component, as multiple distributors may list it under generic descriptions. Confirm that the ordering suffix matches the exact voltage and current specifications required for your design. Ensure the package type aligns with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 10A current rating and 400V reverse voltage are required in a compact GBU package. Consider its thermal dissipation capabilities relative to the expected ambient operating conditions. Evaluate the 220A surge rating against potential inrush currents in the target application to ensure adequate safety margins.

Part Context

This part belongs to Comchip Technology's line of glass passivated bridge rectifiers. These devices are engineered for general-purpose applications where reliability and compact size are critical. The GBU series is widely used in consumer electronics and industrial equipment due to its standardized form factor and proven performance characteristics.

Replacement Considerations

Direct substitutes must match the 10A current rating, 400V reverse voltage, and GBU package dimensions. Verify that alternative components offer comparable surge current ratings and thermal resistance values to maintain system reliability without redesigning the heat dissipation layout.
