GBU3010-BP

Overview

The GBU3010-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It utilizes glass passivated chip junctions and operates within a temperature range of -55°C to +150°C. The device provides an average rectified forward current of 4.0 A at 25°C ambient temperature, or 30 A with a heatsink at 90°C case temperature. It supports a peak repetitive reverse voltage of 1000 V and withstands non-repetitive peak surge currents up to 700 A for half-sine waves. Electrical characteristics include a maximum reverse current of 5 uA at 25°C and a typical junction capacitance of 115 pF.

Feature Summary

• Glass passivated chip junctions ensure high reliability and stable performance under varying conditions.
• Epoxy casing meets UL 94 V-0 flammability ratings for enhanced safety in electronic assemblies.
• High surge forward current capability allows the component to handle transient electrical loads effectively.

Applications

• Power supply units requiring single-phase AC to DC conversion
• Battery charging circuits for automotive or industrial applications
• General-purpose rectification in consumer electronics

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with moisture sensitivity level requirements. Request traceability documentation upon receipt to maintain quality standards throughout the manufacturing process.

Selection Notes

Select this component when a 1000 V reverse voltage rating is required alongside moderate current handling capabilities. Evaluate thermal management needs carefully, as the rated current drops significantly without a heatsink. Compare junction-to-case thermal resistance against available cooling solutions to ensure operation remains within the specified temperature limits during continuous duty cycles.

Part Context

This part belongs to the GBU30005 through GBU3010 series of bridge rectifiers. The series offers various voltage ratings from 50 V to 1000 V while maintaining consistent physical dimensions and current capabilities. The GBU package style facilitates through-hole mounting on printed circuit boards, providing a standardized footprint for power electronics designs.

Replacement Considerations

Direct substitutes must match the 1000 V reverse voltage and 4.0 A/30 A current ratings. Verify that alternative components share the GBU-4 package dimensions and pinout configuration. Ensure replacement parts also feature glass passivation and meet equivalent thermal resistance specifications for reliable integration.
