GBU3006-BP

Overview

The GBU3006-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a 30 A average rectified forward current and a 600 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, a reverse leakage current of 5 µA at 25°C, and a non-repetitive peak surge current capability of 700 A under an 8.3 ms half-sine wave condition. 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 thermal conditions.
• Epoxy body meets UL 94 V-0 flammability rating, providing enhanced safety in enclosed electronic assemblies.
• High surge forward current capability allows the component to withstand transient electrical loads without failure.

Applications

• AC-to-DC power supply circuits requiring robust rectification at moderate currents.
• Battery charging systems utilizing standard bridge configurations.
• General-purpose DC power conversion modules operating within specified thermal limits.

Procurement Notes

Verify authenticity through authorized MCC distributors due to industry counterfeiting risks. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with manufacturer guidelines to maintain lead integrity. Request traceability documentation upon receipt to validate genuine sourcing and quality standards.

Selection Notes

Select this component for applications demanding 30 A continuous current handling with 600 V blocking capability. Evaluate thermal management requirements, as derating curves indicate reduced current capacity at elevated ambient temperatures. Verify footprint compatibility with the GBU package dimensions before integration into printed circuit board designs.

Part Context

This part belongs to the GBU3000 series, which offers standardized voltage ratings ranging from 50 V to 1000 V. The series maintains consistent mechanical and thermal profiles across variants, allowing designers to swap voltage ratings while retaining the same PCB layout and heatsinking infrastructure for different power supply specifications.

Replacement Considerations

Cross-reference with other GBU-series bridge rectifiers from different manufacturers that match the 30 A current and 600 V voltage ratings. Verify pinout compatibility and physical dimensions to ensure direct replacement without modifying the host circuit board or mounting hardware.
