GBU3510

Overview

The GBU3510 is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It utilizes glass passivated silicon die within a GBU-4 through-hole package. The device supports an average forward current of 17.5 A and withstands a peak repetitive reverse voltage of 1 kV. Key electrical parameters include a maximum forward voltage drop of 1.05 V at rated current, a non-repetitive peak surge current of 900 A, and a low reverse leakage current of 5 µA. It operates reliably across a temperature range from -55 °C to +150 °C.

Feature Summary

• Glass passivated chip junction for enhanced reliability and stability
• High surge current capability designed to handle transient loads
• Low forward voltage drop for improved power efficiency
• Suitable for automatic insertion into printed circuit boards

Applications

• AC to DC conversion in general-purpose power supplies
• Power stages in household appliances
• Industrial control systems requiring robust rectification
• Battery charging circuits

Procurement Notes

Verify the manufacturer designation as Micro Commercial Components (MCC) when sourcing this component. Confirm the specific suffix BP if required for compliance or packaging specifications. Ensure the GBU-4 package type matches your PCB footprint requirements. Cross-reference datasheets to validate the 17.5 A rating against similar 35 A series parts which may have different thermal characteristics.

Selection Notes

Select this component for applications requiring a compact through-hole bridge rectifier with high surge tolerance. The 1 kV rating suits standard mains voltage rectification. Compare the 17.5 A continuous current limit against load requirements; higher current variants like the GBJ3510 exist but differ in package style. Ensure thermal management aligns with the specified operating temperature range.

Part Context

This part belongs to the GBU3510 series of single-phase bridge rectifiers. It is distinct from the GBJ3510, which shares similar electrical ratings but uses a different surface-mount compatible lead frame design. The GBU series is characterized by its radial through-hole configuration, making it suitable for standard PCB mounting techniques.

Replacement Considerations

Direct substitutes include other manufacturers' GBU3510 equivalents. Verify pinout compatibility and thermal resistance values. Parts like the GBU3510-BP from MCC are identical. Check for alternative packages such as GBJ3510 if board space allows, noting the difference in mounting style.
