GBU3510-BP

Overview

The GBU3510-BP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a glass passivated chip junction and operates with a peak repetitive reverse voltage of 1000 V. The device supports an average rectified forward current of 35 A at a case temperature of 115°C, or 4 A without a heatsink at 25°C. Electrical characteristics include a maximum forward voltage of 1.05 V at 17.5 A and a reverse leakage current of 5 µA at 25°C. It withstands a non-repetitive peak surge current of 900 A for a 1 ms square wave. The component utilizes a GBU-4 through-hole package.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• High surge forward current capability
• Epoxy material meets UL 94 V-0 flammability rating
• Halogen-free "Green" device construction

Applications

• Printed circuit board mounting in power supply circuits
• General purpose AC to DC conversion
• Industrial equipment requiring high reliability rectification

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm the "BP" suffix indicates RoHS compliance and lead-free finish. Ensure ordering quantities match bulk packaging specifications of 20 pieces per tube. Validate that the specific lot meets required quality standards for handling and storage conditions.

Selection Notes

Select this component when a 1000 V blocking voltage and 35 A continuous current are required in a GBU package. Consider thermal management if operating near the 115°C case temperature limit. Verify that the 1.05 V forward voltage drop aligns with efficiency requirements. Ensure the PCB layout accommodates the radial through-hole pin configuration and recommended mounting torque.

Part Context

This part belongs to the GBU series of bridge rectifiers from Micro Commercial Components. The series offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 35 A current capacity. The GBU3510 specifically targets applications needing high voltage isolation within a standard through-hole footprint compatible with automated assembly processes.

Replacement Considerations

Cross-reference with other manufacturers offering GBU-4 packaged 35 A / 1000 V bridge rectifiers. Verify identical pinout configurations and mechanical dimensions before substitution. Ensure equivalent thermal resistance and surge current capabilities match the original design requirements.
