GBU2004-BP

Overview

The GBU2004-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 20 A average rectified forward current and a 400 V peak repetitive reverse voltage. The device utilizes glass-passivated chip junctions for reliability and meets UL 94 V-0 flammability ratings. Electrical characteristics include a maximum forward voltage of 1.0 V at 10 A, a reverse leakage current of 5 µA at 25°C, and a non-repetitive peak surge current of 240 A. Thermal resistance from junction to case is 1 °C/W, with an operating temperature range spanning -55°C to +150°C.

Feature Summary

• Glass passivated chip junctions provide high surge overload capability and long-term stability.
• Epoxy casing meets UL 94 V-0 flammability classification for enhanced safety.
• Lead-free finish and RoHS compliance support environmentally conscious manufacturing.

Applications

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

Procurement Notes

Verify authenticity through authorized MCC distributors or direct channels to avoid counterfeit components. Confirm the BP suffix indicates RoHS compliance and lead-free construction. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.

Selection Notes

Select this component when a 20 A current rating and 400 V blocking voltage are required in a GBU surface-mount package. Evaluate thermal management requirements based on the specified junction-to-case resistance. Consider derating curves for ambient temperatures exceeding standard test conditions.

Part Context

This part belongs to the GBU2000 series, which covers voltages from 50 V to 1000 V within the same physical footprint. The GBU2004 variant specifically addresses applications requiring 400 V isolation while maintaining high current handling capabilities common in medium-power electronic designs.

Replacement Considerations

Cross-reference with other GBU2004 variants from different manufacturers ensuring identical pinout, current rating, and voltage specifications. Verify that substitute components meet the same thermal and mechanical mounting torque requirements.
