Overview
The GBU2508-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features glass passivated chip junctions and operates with a peak repetitive reverse voltage of 800 V. The device supports an average rectified forward current of 25 A at 25°C, or 3.5 A without a heatsink. It withstands a non-repetitive peak surge current of 600 A for a 1ms square wave. Electrical characteristics include a maximum forward voltage of 1.0 V at 12.5 A and a reverse leakage current of 5 µA at 25°C. The component operates within a junction temperature range of -55°C to 150°C.
Feature Summary
- Glass passivated chip junctions provide reliable operation and protection against voltage transients.
- Epoxy material meets UL 94 V-0 flammability ratings for safety compliance.
- Halogen-free 'Green' device construction adheres to environmental standards.
- Lead-free finish ensures RoHS compliance.
Applications
- Printed circuit board mounting for general power supply applications
- AC to DC conversion in industrial equipment
- Power adapters and chargers
Procurement Notes
Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm the BP suffix indicates RoHS compliance and bulk packaging. Ensure storage conditions align with manufacturer guidelines to maintain product integrity before assembly.
Selection Notes
Select this component when an 800 V blocking voltage and 25 A continuous current are required. Verify thermal management requirements, as current derating applies above 25°C ambient temperature. Ensure the GBU package dimensions fit the target PCB layout and mounting torque specifications.
Part Context
This part belongs to the GBU25005 through GBU2510 series of bridge rectifiers. All variants share identical physical dimensions and thermal characteristics but differ in their peak repetitive reverse voltage ratings, which range from 50 V to 1000 V across the series.
Replacement Considerations
Compatible substitutes include GBU2508-HF from Comchip Technology. Verify that alternative parts match the 800 V reverse voltage, 25 A forward current, and GBU package footprint before implementation.
FAQ
