Overview
The GBU3008-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features glass passivated chip junctions and epoxy meeting UL 94 V-0 flammability ratings. The device supports an average rectified forward current of 30 A at 25°C without a heatsink, with a peak repetitive reverse voltage of 800 V. Maximum surge forward current capability reaches 350 A for an 8.3 ms half-sine wave. Electrical characteristics include a maximum forward voltage of 1.0 V and a reverse current of 5 uA at 25°C. Thermal resistance from junction to case is 1 °C/W, while junction to ambient is 22 °C/W without a heatsink.
Feature Summary
- Glass passivated chip junction construction
- High surge forward current capability
- Epoxy meets UL 94 V-0 flammability rating
Applications
- General purpose AC to DC power supply conversion
- Industrial rectification circuits
- Power adapter applications
Procurement Notes
Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm RoHS compliance via the "BP" suffix designation. Ensure storage conditions align with manufacturer guidelines to maintain component integrity prior to assembly.
Selection Notes
Select this model for applications requiring 800 V blocking voltage and 30 A continuous current. Consider thermal management strategies if operating near the 30 A limit without a heatsink. Verify package dimensions against PCB layout requirements before finalizing the design.
Part Context
This component belongs to the GBU3000 series of bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 30 A current capacity. The GBU3008-BP specifically addresses high-voltage single-phase rectification needs within this lineup.
Replacement Considerations
Compatible substitutes include other GBU30xx series variants with matching voltage ratings, such as GBU3006-BP or GBU3010-BP. Cross-brand replacements must match the 30 A current rating, 800 V reverse voltage, and GBU package footprint.
