GBU8K-BP

Overview

The GBU8K-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features an 8 A average forward rectified current rating and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a glass-passivated silicon junction for reliable operation. Key electrical parameters include a maximum non-repetitive peak forward surge current of 200 A, a typical forward voltage drop of 1 V at rated current, and a low reverse leakage current of 5 µA. It operates within a temperature range of -55 °C to +150 °C junction temperature. The component is housed in a GBU surface-mount package with solder pad termination.

Feature Summary

• Glass-passivated silicon junction construction ensures high reliability and stable performance under varying thermal conditions.
• GBU surface-mount package design facilitates automated assembly and efficient printed circuit board layout.
• High surge overload capability allows the device to withstand transient current spikes during power-up or fault conditions.

Applications

• AC-DC power supply circuits requiring compact bridge rectification
• General-purpose rectification in industrial control systems
• Battery charging applications with moderate voltage requirements

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and material compliance. Ensure that the procurement source provides valid RoHS and REACH documentation as required by project specifications. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and authenticity before finalizing orders.

Selection Notes

Select this component when a surface-mount bridge rectifier with 800 V blocking voltage and 8 A continuous current capacity is required. Compare the GBU package dimensions against available PCB real estate to ensure mechanical fit. Evaluate the thermal management requirements based on the 150 °C maximum junction temperature rating and expected ambient operating conditions.

Part Context

The GBU8K-BP belongs to the GBU series of single-phase bridge rectifiers from Micro Commercial Components. This series offers various voltage ratings and current capacities within the same standardized GBU footprint. The 'BP' suffix typically denotes lead-free and halogen-free compliance, aligning with modern environmental regulations for electronic components.

Replacement Considerations

Direct replacements must match the 8 A current rating, 800 V reverse voltage, and GBU package outline. Verify equivalent forward voltage and surge current capabilities. Check for identical pin configuration to ensure compatibility without PCB redesign.
