GBU20005-BP

Overview

The GBU20005-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 20 A average rectified forward current and a 50 V peak repetitive reverse voltage. The device utilizes glass passivated chip junctions for reliability and meets UL 94 V-0 flammability ratings with epoxy encapsulation. Electrical characteristics include a maximum forward voltage of 1.0 V at 10 A, a reverse leakage current of 5 uA at 25°C, and a non-repetitive peak surge current capability of 240 A. Thermal resistance from junction to case is 1 °C/W, supporting operation within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated chip junction construction ensures high reliability and stable performance under varying electrical loads.
• Epoxy casing complies with UL 94 V-0 flammability standards, providing robust physical protection and safety.
• High surge forward current capability allows the component to withstand transient overcurrent events without failure.

Applications

• General-purpose AC to DC power conversion in industrial equipment
• Battery charging circuits requiring moderate current handling
• DC power supply units for consumer electronics

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement channels due to industry counterfeiting risks. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with manufacturer guidelines to maintain material integrity prior to assembly.

Selection Notes

Select this component when a 20 A continuous current rating and 50 V blocking voltage are required. Evaluate thermal management needs based on the 25 °C/W junction-to-ambient resistance if heatsinking is not utilized. Verify that the 240 A surge capacity matches the circuit's inrush requirements.

Part Context

This part belongs to the GBU series of bridge rectifiers, which offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 20 A current capacity. The GBU package style facilitates through-hole mounting with specific terminal dimensions defined in the datasheet.

Replacement Considerations

Cross-reference with other GBU20005 variants from different manufacturers ensuring identical 20 A/50 V specifications. Verify pinout compatibility and mechanical dimensions before substitution to ensure proper PCB integration.
